Our Corporate Information

Chembio Diagnostic Systems Inc. was formed in 1985. Since inception we have been involved in developing, manufacturing, selling and distributing medical diagnostic tests, including rapid tests that detect a number of infectious diseases. On May 5, 2004, Chembio Diagnostic Systems Inc. completed a merger through which it became a wholly-owned subsidiary of Chembio Diagnostics, Inc., formerly known as Trading Solutions.com, Inc. As a result of this transaction, the management and business of Chembio Diagnostic Systems Inc. became the management and business of the Company. Our principal executive offices are located at 3661 Horseblock Road, Medford, New York 11763. Our telephone number is (631) 924-1135. Our website address is www.chembio.com.

Our Business

Chembio Diagnostics, Inc. (referred to collectively with its subsidiaries as the “Company”) and its subsidiaries develop, manufacture and market rapid diagnostic tests that detect infectious diseases. The Company’s main products presently commercially available are three rapid tests for the detection of HIV antibodies in whole blood, serum and plasma samples, all of which employ lateral flow technology and two of which were approved by the FDA in 2006 and a fourth rapid HIV test, developed on our patented Dual Path Platform (DPP®) technology, for the detection of antibodies to HIV in oral fluid samples, as well as whole blood, serum and plasma samples. The products which employ lateral flow technology are manufactured and sold under a non-exclusive license we have from Inverness Medical Innovations, Inc. (“Inverness”), which is also our exclusive marketing partner for the FDA-approved products in the United States (as well as Europe and Asia for one of these two known as the “barrel” format product) under its Clearview® brand. Inverness launched its marketing of these products in the United States in February 2007. Chembio’s two HIV STAT-PAK® rapid HIV tests (in cassette and dipstick formats) are marketed outside the United States through different partners and channels under our license from Inverness.

We have a history of losses, and we continue to incur operating and net losses. We have non-exclusive licenses to lateral flow patents held by Inverness and to reagents including those that are used in our HIV rapid tests. These licenses do not necessarily insulate us from patent challenges by other patent holders.

RISK FACTORS

You should carefully consider each of the following risk factors and all of the other information provided in this Annual Report. The risks described below are those we currently believe may materially affect us. An investment in our Common Stock involves a high degree of risk, and should be considered only by persons who can afford the loss of their entire investment.

Risks related to our industry, business and strategy

Because we may not be able to obtain necessary regulatory approvals for some of our products, we may not generate revenues in the amounts we expect, or in the amounts necessary to continue our business.

All of our proposed and existing products are subject to regulation in the U.S. by the U.S. Food and Drug Administration, the U.S. Department of Agriculture and/or other domestic and international governmental, public health agencies, regulatory bodies or non-governmental organizations. In particular, we are subject to strict governmental controls on the development, manufacture, labeling, distribution and marketing of our products. The process of obtaining required approvals or clearances varies according to the nature of, and uses for, a specific product. These processes can involve lengthy and detailed laboratory testing, human or animal clinical trials, sampling activities, and other costly, time-consuming procedures. The submission of an application to a regulatory authority does not guarantee that the authority will grant an approval or clearance for product. Each authority may impose its own requirements and can delay or refuse to grant approval or clearance, even though a product has been approved in another country.

The time taken to obtain approval or clearance varies depending on the nature of the application and may result in the passage of a significant period of time from the date of submission of the application. Delays in the approval or clearance processes increase the risk that we will not succeed in introducing or selling the subject products, and we may determine to devote our resources to different products.

Changes in government regulations could increase our costs and could require us to undergo additional trials or procedures, or could make it impractical or impossible for us to market our products for certain uses, in certain markets, or at all.

Changes in government regulations may adversely affect our financial condition and results of operations because we may have to incur additional expenses if we are required to change or implement new testing, manufacturing and control procedures. If we are required to devote resources to develop such new procedures, we may not have sufficient resources to devote to research and development, marketing, or other activities that are critical to our business.

For example, the European Union and other jurisdictions have a requirement that diagnostic medical devices used to test human biological specimens must receive regulatory approval known as a CE mark, or be registered under the ISO 13.485 medical device directive. The letters “CE” are the abbreviation of the French phrase “Conforme Européene,” which means “European conformity.” ISO (“International Organization for Standardization”) is the world’s largest developer of standards with 148 member countries. As such, export to the European and other jurisdictions without the CE or ISO 13.485 mark is not possible. In 2007, we received ISO 13.485 certification, in 2008, we received a CE registration for our Chagas test, and during 2009 we expect to receive CE registration for our two FDA approved HIV tests. However, there are no assurances that we will be able to secure this certification although we are not aware of any material reason why such approval will not be granted. However, if for any reason a CE registration is not granted, our ability to export our products could be adversely impacted.

We can manufacture and sell our products only if we comply with regulations of government agencies such as the FDA and the USDA. We have implemented a quality system that is intended to comply with applicable regulations. Although FDA approval is not required for the export of our products, there are export regulations promulgated by the FDA that specifically relate to the export of our products. Although we believe that we meet the regulatory standards required for the export of our products, these regulations could change in a manner that could adversely impact our ability to export our products.

Our products may not be able to compete with new diagnostic products or existing products developed by well-established competitors, which would negatively affect our business.

The diagnostic industry is focused on the testing of biological specimens in a laboratory or at the point-of-care and is highly competitive and rapidly changing. Our principal competitors often have considerably greater financial, technical and marketing resources than we do. Several companies produce diagnostic tests that compete directly with our testing product line, including but not limited to, Orasure Technologies, Inverness Medical and Trinity Biotech. As new products enter the market, our products may become obsolete or a competitor’s products may be more effective or more effectively marketed and sold than ours. Although we have no specific knowledge of any competitor’s product that will render our products obsolete, if we fail to maintain and enhance our competitive position or fail to introduce new products and product features, our customers may decide to use products developed by our competitors, which could result in a loss of revenues and cash flow.

We are developing an oral fluid rapid HIV test as well as other applications utilizing our Dual Path Platform technology, which we believe could enhance our competitive position in HIV rapid testing and other fields. During 2008 we completed development of our initial DPP® products for the detection of antibodies to HIV 1 & 2 in oral fluid as well as blood samples, and a product for the detection of canine leishmaniasis. However we still have technical, manufacturing, regulatory and marketing challenges to meet before we will know whether we can successfully commercialize products incorporating this technology. There can be no assurance that we will overcome these challenges.

We have granted Inverness exclusive rights to market our SURE CHECK® HIV 1/2 in the United States, Europe and Asia and our HIV 1/2 STAT PAK® in the U.S. Inverness has no rapid HIV tests that are approved for marketing in the U.S., we are not aware of any rapid HIV products that Inverness is even contemplating for the U.S., and Inverness is obligated to inform us of any such products as soon as it is able to do so. Inverness does have rapid HIV tests manufactured by certain of its subsidiaries outside the U.S. that are being actively marketed outside the U.S., primarily in developing countries. Our HIV 1/2 STAT PAK cassette and dipstick products compete against these Inverness products, and we specifically acknowledge in our agreements with Inverness the existence of such other products. Moreover, except for a product in the HIV barrel field as defined in our agreement with Inverness, Inverness is permitted under our agreements to market certain types of permitted competing rapid HIV tests in the U.S. Under these conditions, we could choose to terminate the applicable agreement with Inverness or change the agreement to a non-exclusive agreement, and Inverness would expand the lateral flow license granted to the Company to allow the Company to market the product independently or through other marketing partners. While we believe that Inverness is committed to successfully marketing our products particularly in the U.S. and other developed countries where our products are or become approved for marketing, Inverness may choose to develop or acquire competing products for marketing in the U.S. as well as other markets where they are marketing our SURE CHECK® HIV 1/2 product, and such an action could have at least a temporary material adverse effect on the marketing of these products until such time as alternative marketing arrangements could be implemented. While we also believe that the expansion of our license to the Inverness lateral flow patents substantially facilitates our ability to make alternative marketing arrangements, there can be no assurance that the modification of marketing arrangements and the possible corresponding delays or suspension of sales would not have a material adverse effect on our business.

In addition, the point-of-care diagnostics industry is undergoing rapid technological changes, with frequent introductions of new technology-driven products and services. As new technologies become introduced into the point-of-care diagnostic testing market, we may be required to commit considerable additional efforts, time and resources to enhance our current product portfolio or develop new products. We may not have the available time and resources to accomplish this and many of our competitors have substantially greater financial and other resources to invest in technological improvements. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers, which would materially harm our operating results.

We own no issued patents covering lateral flow technology, and the field of lateral flow technology is complex and characterized by a substantial amount of litigation, so the risk of potential patent challenges is ongoing for us in spite of our pending patent applications.

Although we have been granted non-exclusive licenses to the lateral flow patents owned by Inverness Medical Innovations, Inc. , there is no assurance that their lateral flow patents will not be challenged or that licenses from other parties may not be required, if available at all. In the event that it is determined that a license is required and it is not possible to negotiate a license agreement under a necessary patent, we may be able to modify our HIV rapid test products and other products such that a license would not be necessary. However, this alternative could delay or limit our ability to sell these products in the U.S. and other markets, which would adversely affect our results of operations, cash flows and business.

During 2008 Inverness and Church & Dwight commenced a patent infringement suit against Orasure Technologies, Inc. based on Orasure’s alleged infringement of one of Church & Dwight’s and Inverness’ (the parties have joint rights to this patent) main patents covering lateral flow technology. Orasure has alleged that it does not infringe such patent and that such patent is invalid. A judgment adverse to Inverness stating that Orasure’s product does not infringe the Inverness patent or invalidating the Inverness patent, which patent Inverness has successfully used to restrict competition in selected product areas core to Inverness’ business, could potentially open up the US rapid HIV test market to other competitors, and thereby have a material and adverse effect on our business. A settlement by Inverness with Orasure, depending on its terms, could also have a material effect on our business, which effect could be beneficial or detrimental.

On March 13, 2007, our Dual Path Platform Immunoassay Device patent application was issued as United States patent no. 7,189,522. Additional protection for this intellectual property is pending worldwide. This platform has shown improved sensitivity as compared with conventional platforms in a number of preliminary studies using well characterized samples. We believe that this new platform is outside of the scope of currently issued patents in the field of lateral flow technology, thereby offering the possibility of a greater freedom to operate. However there can be no assurance that our patents or our products incorporating the patent claims will not be challenged at some time in the future.

New developments in health treatments or new non-diagnostic products may reduce or eliminate the demand for our products.

The development and commercialization of products outside of the diagnostics industry could adversely affect sales of our products. For example, the development of a safe and effective vaccine to HIV or treatments for other diseases or conditions that our products are designed to detect, could reduce, or eventually eliminate, the demand for our HIV or other diagnostic products and result in a loss of revenues.

We may not have sufficient resources to effectively introduce and market our products, which could materially harm our operating results.

Introducing and achieving market acceptance for our rapid HIV tests and other new products will require substantial marketing efforts and will require us or our contract partners, sales agents, or distributors to make significant expenditures of time and money. In some instances we will be significantly or totally reliant on the marketing efforts and expenditures of our contract partners, sales agents, distributors. If they do not have or commit the expertise and resources to effectively market the products that we manufacture, our operating results will be materially harmed.

The success of our business depends, in addition to the market success of our products, on our ability to raise additional capital through the sale of debt or equity or through borrowing, and we may not be able to raise capital or borrow funds in amounts necessary to continue our business, or at all.

Our revenues and gross margins have increased significantly in recent periods, and our operating and net losses have decreased significantly in recent periods. Nevertheless we have sustained significant operating losses in 2008, 2007 and 2006. At December 31, 2008, we had a stockholders’ equity of $2.58 million and a working capital surplus of $1.66 million. The Company estimates that its resources are sufficient to fund its needs through the end of 2009 and beyond or that, in the alternative, it could raise additional capital although the terms under which that capital could be raised would likely be very dilutive to current shareholders. The Company’s liquidity and cash requirements will depend on several factors. These factors include (1) the level of revenues (the Company received $340,000 in 2009 for license fees for which we need to meet certain milestones to earn); (2) the extent to which, if any, that revenue level improves operating cash flows; (3) the Company’s investments in research and development, facilities, marketing, regulatory approvals, and other investments it may determine to make; and (4) the investment in capital equipment (including production equipment of $323,500 that the Company has contracted for) and the extent to which it improves cash flow through operating efficiencies. There are no assurances that the Company will become profitable or generate positive cash flow by the end of 2009 or, in the alternative, be successful in raising sufficient capital to fund its needs through 2009.

Our objective of increasing international sales is critical to our business plan and if we fail to meet this objective, we may not generate revenues in the amounts we expect, or in amounts necessary to continue our business.

We intend to attempt to increase international sales of our products. A number of factors can slow or prevent international sales, or substantially increase the cost of international sales, including:

·	regulatory requirements and customs regulations;

·	cultural and political differences;

·	foreign exchange rates, currency fluctuations and tariffs;

·	dependence on and difficulties in managing international distributors or representatives;

·	the creditworthiness of foreign entities;

·	difficulties in foreign accounts receivable collection; and

·	economic conditions and the absence of available funding sources.

If we are unable to increase our revenues from international sales, our operating results will be materially harmed.

We rely on trade secret laws and agreements with our key employees and other third parties to protect our proprietary rights, and we cannot be sure that these laws or agreements adequately protect our rights.

We believe that factors such as the technological and creative skills of our personnel, strategic relationships, new product developments, frequent product enhancements and name recognition are essential to our success. All our management personnel are bound by non-disclosure agreements. If personnel leave our employment, in some cases we would be required to protect our intellectual property rights pursuant to common law theories which may be less protective than provisions of employment, non-competition or non-disclosure agreements.

We seek to protect our proprietary products under trade secret and copyright laws, enter into license agreements for various materials and methods employed in our products, and enter into strategic relationships for distribution of the products. These strategies afford only limited protection. We currently have no foreign patents, though we are seeking patent protection in several foreign jurisdictions for our DPP® technology. We have licenses to reagents (antigens and peptides) used in several of our products and products under development We also have a license to manufacture, use and sell products used to screen for antibodies to HIV-2. In addition, our SURE CHECK®, DPP® and STAT-PAK® trademarks have been registered in the U.S. Despite our efforts to protect our proprietary assets, and respect the intellectual property rights of others, we participate in several markets where intellectual property rights protections are of little or no value. This can place our products and our company at a competitive disadvantage.

During 2008 and in the first quarter of 2009 we terminated a number of employees who have had access to proprietary and confidential information. In connection with the termination of several of these employees whose positions were terminated, individuals executed severance agreements that include strong covenants by these former employees to keep our proprietary information confidential. Despite these and other efforts we make to protect our confidential information, unauthorized parties may attempt to copy aspects of our products or to obtain information that we regard as proprietary. We may be required to expend substantial resources in asserting or protecting our intellectual property rights, or in defending suits related to intellectual property rights. Disputes regarding intellectual property rights could substantially delay product development or commercialization activities because some of our available funds would be diverted away from our business activities. Disputes regarding intellectual property rights might include state, federal or foreign court litigation as well as patent interference, patent reexamination, patent reissue, or trademark opposition proceedings in the U.S. Patent and Trademark Office.

To facilitate development and commercialization of a proprietary technology base, we may need to obtain additional licenses to patents or other proprietary rights from other parties. Obtaining and maintaining these licenses, which may not be available, may require the payment of up-front fees and royalties. In addition, if we are unable to obtain these types of licenses, our product development and commercialization efforts may be delayed or precluded.

Our continued growth depends on retaining our current key employees and attracting additional qualified personnel, and we may not be able to do so.

Our success will depend to a large extent upon the skills and experience of our executive officers, management and sales, marketing, operations and scientific staff. We may not be able to attract or retain qualified employees in the future due to the intense competition for qualified personnel among medical products businesses, geographic considerations, our ability to offer competitive compensation , relocation packages, benefits, and/or other reasons.

If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will adversely affect our ability to effectively manufacture, sell and market our products to meet the demands of our strategic partners in a timely fashion, or to support internal research and development programs. Although we believe we will be successful in attracting and retaining qualified personnel, competition for experienced scientists and other personnel from numerous companies and academic and other research institutions may limit our ability to do so on acceptable terms.

We have entered into employment contracts with our President, Lawrence Siebert, and our Senior Vice President of Research and Development, Javan Esfandiari. Due to the specific knowledge and experience of these executives regarding the industry, technology and market, the loss of the services of either one of them would likely have a material adverse effect on the Company. The contract with Mr. Siebert had a term of two years ending May 2008, which the board of directors extended for one year, and the contract with Mr. Esfandiari has a term of three years ending March 2010. We have obtained a key man insurance policy for Mr. Esfandiari.

We believe our success depends on our ability to participate in large government programs in the U.S. and worldwide and we may not be able to do so.

We believe it to be in our best interests to meaningfully participate in the PEPFAR Program, UN Global Fund initiatives and other programs funded by large donors. We have initiated several strategies to participate in these programs. Participation in these programs requires alignment and engagement with the many other participants in these programs including the World Health Organization, U.S. Center for Disease Control, U.S. Agency for International Development, foreign governments and their agencies, non-governmental organizations, and HIV service organizations. If we are unsuccessful in our efforts to participate in these programs, our operating results could be materially harmed.

We have a history of incurring net losses and we cannot be certain that we will be able to achieve profitability.

Since the inception of Chembio Diagnostic Systems, Inc. in 1985 and through the period ended December 31, 2008, we have incurred net losses. As of December 31, 2008, we have an accumulated deficit of $37 million. We incurred net losses of $1.9 million and $2.6 million in 2008 and 2007, respectively.

We expect to continue to make substantial expenditures for sales and marketing, regulatory submissions, product development and other purposes, though within reasonable limitations that we believe are necessary in order to continue our making progress toward profitability without requiring additional capital. Our ability to achieve profitability in the future will primarily depend on our ability to increase sales of our products, reduce production and other costs and successfully introduce new products and enhanced versions of our existing products into the marketplace. If we are unable to increase our revenues at a rate that is sufficient to achieve profitability, or adequately control and reduce our operating costs, our operating results would be materially harmed.

To the extent that we are unable to obtain sufficient product liability insurance or that we incur product liability exposure that is not covered by our product liability insurance, our operating results could be materially harmed.

We may be held liable if any of our products, or any product which is made with the use or incorporation of any of the technologies belonging to us, causes injury of any type or is found otherwise unsuitable during product testing, manufacturing, marketing, sale or usage. We have obtained product liability insurance, we have never received a product liability claim, and have generally not seen product liability claims for screening tests that are accompanied by appropriate disclaimers. Nevertheless, in the event there is a claim, this insurance may not fully cover our potential liabilities. In addition, as we attempt to bring new products to market, we may need to increase our product liability coverage which would be a significant additional expense that we may not be able to afford. If we are unable to obtain sufficient insurance coverage at an acceptable cost to protect us, we may be forced to abandon efforts to commercialize our products or those of our strategic partners, which would reduce our revenues.

Risks related to our Common Stock

In the past, our Common Stock has been classified as penny stock, and it continues to be extremely illiquid, so investors may not be able to sell as much stock as they want at prevailing market prices.

In the past, our Common Stock has been classified as penny stock. Penny stocks generally are equity securities with a price of less than $5.00 and trade on the over-the-counter market. As a result, an investor may find it more difficult to dispose of or obtain accurate quotations as to the price of the securities that are classified as penny stocks. The “penny stock” rules adopted by the Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), subject the sale of the shares of penny stock issuers to regulations that impose sales practice requirements on broker-dealers, causing many broker-dealers to not trade penny stocks or to only offer the stocks to sophisticated investors that meet specified net worth or net income criteria identified by the Commission. These regulations contribute to the lack of liquidity of penny stocks.

At the present time, transactions in our Common Stock are not subject to the “penny stock” rules because our average revenue for 2006, 2007 and 2008 exceeded $6 million per year. However, there can be no assurance that transactions in our Common Stock will not be subject to the “penny stock” rules in the future.

The average daily trading volume of our Common Stock on the over-the-counter market was less than 16,000 shares per day over the three months ended March 16, 2009. If limited trading in our stock continues, it may be difficult for investors to sell their shares in the public market at any given time at prevailing prices.

Sales of a substantial number of shares of our Common Stock into the public market by the selling stockholders may result in significant downward pressure on the price of our Common Stock and could affect the ability of our stockholders to realize the current trading price of our Common Stock.

At the time that this post-effective amendment to the registration statement is declared effective by the SEC, a significant number of shares of our Common Stock will be eligible to be immediately sold in the market.

As of March 18, 2009, our Common Stock was trading at $0.08 cents per share. If a large number of selling stockholders sell in large amounts after the post-effective amendment to the registration statement is declared effective, significant downward pressure could be placed on our stock price.

You will experience substantial dilution upon the exercise warrants underlying common stock that we are currently registering.

There are 8,099,680 shares of common stock underlying warrants registered in this registration statement, and 2,949,197 shares of common stock underlying warrants and options registered in another registration statement. As of March 19, 2008, we have approximately 13 million warrants and options outstanding. As a result, the exercise of the outstanding warrants and options will result in substantial dilution to the holders of our Common Stock.

Our management and larger stockholders exercise significant control over our Company and may approve or take actions that may be adverse to your interests.

As of March 17, 2009, our named executive officers, directors and 5% stockholders beneficially owned approximately 63.7% of our voting power. For the foreseeable future, to the extent that our current stockholders vote similarly, they will be able to exercise control over many matters requiring approval by the board of directors or our stockholders. As a result, they will be able to:

·	control the composition of our board of directors;

·	control our management and policies;

·	determine the outcome of significant corporate transactions, including changes in control that may be beneficial to stockholders; and

·	act in each of their own interests, which may conflict with, or be different from, the interests of each other or the interests of the other stockholders.

USE OF PROCEEDS

We will not receive proceeds from the sale of shares under this prospectus by the selling security holders.

DETERMINATION OF OFFERING PRICE

We are not selling any common stock in this offering. We anticipate that the Selling Stockholders will offer the Shares for sale at prevailing market prices on the OTC Bulletin Board on the date of such sale. We will not receive any proceeds from these sales.

DILUTION

We currently file reports with the SEC, and we are not selling any common stock in this offering. The selling security holders are the current stockholders of the Company.

SELLING SECURITY HOLDERS

The securities are being offered by the named selling security holders below. The selling security holders hold one or more of the following securities which are described in section “Description of Securities”: common stock and warrants to purchase common stock exercisable at prices ranging from $0.40 per share to $4.00 per share. However, the table below assumes the immediate exercise of all warrants to purchase common stock, without regard to other factors which may determine whether such rights of conversion or purchase are exercised. These factors include but are not limited to terms of these agreements, and the specific exercise price of the securities held by such selling security holder and its relation to the market price. The selling security holders may from time to time offer and sell pursuant to this prospectus up to an aggregate of 1,053,940 shares of our common stock now owned by them, up to an aggregate of 7,045,740 shares of common stock issuable pursuant to the exercise of warrants, and additional shares of common stock which Selling Stockholders may receive at a later date pursuant to the anti-dilution provisions of certain warrants. The selling security holders may, from time to time, offer and sell any or all of the shares that are registered under this prospectus, although they are not obligated to do so.

The following table sets forth, to the Company’s best knowledge and belief, with respect to the selling security holders:

·	the number of shares of common stock beneficially owned as of March 18, 2009 and prior to the offering contemplated hereby;

·	the number of shares of common stock eligible for resale and to be offered by each selling security holder pursuant to this prospectus;

PLAN OF DISTRIBUTION

The Shares covered by this Prospectus are being registered by us for the account of the Selling Stockholders.

The Shares offered by this Prospectus may be sold from time to time directly by or on behalf of the Selling Stockholders in one or more transactions on the OTC Bulletin Board or on any stock exchange on which the Common Stock may be listed at the time of sale, in privately negotiated transactions, or through a combination of these methods. The Selling Stockholders may sell Shares through one or more agents, brokers or dealers or directly to purchasers. These brokers or dealers may receive compensation in the form of commissions, discounts or concessions from the Selling Stockholders and/or purchasers of the Shares, or both. Compensation as to a particular broker or dealer may be in excess of customary commissions. The Selling Stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale or non-sale related transfer. If a Selling Stockholder is an employee, officer or director of the Company, he or she will be subject to our policies concerning trading and other transactions in the Company’s securities.

Each Selling Stockholder of the Shares and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their Shares on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling the Shares:

·	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

·	block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

·	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

·	an exchange distribution in accordance with the rules of the applicable exchange;

·	privately negotiated transactions;

·	settlement of short sales entered into after the date of this Prospectus;

·	broker-dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share;

·	a combination of any such methods of sale;

·	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; or

·	any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this Prospectus. There is no assurance that the Selling Stockholders will sell all or a portion of the stock being offered hereby.

In connection with the sale of Shares, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Shares in the course of hedging the positions they assume. The Selling Stockholders may also sell the Shares short and deliver these Shares to close out short positions, or loan or pledge the Shares to broker- dealers or other financial institutions that in turn may sell these Shares. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions that require the delivery to the broker-dealer or other financial institution of the Shares, which the broker-dealer or other financial institution may resell pursuant to this Prospectus, or enter into transactions in which a broker-dealer makes purchases as a principal for resale for its own account or through other types of transactions.

In connection with the sales, a Selling Stockholder and any participating broker or dealer may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions they receive and the proceeds of any sale of Shares may be deemed to be underwriting discounts or commissions under the Securities Act. A Selling Stockholder who is deemed to be an “underwriter” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act. The Selling Stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M. Regulation M may limit the timing of purchases and sales of shares of our Common Stock by the Selling Stockholders and any other person. Furthermore, Regulation M may restrict, for a period of up to five business days prior to the commencement of the distribution, the ability of any person engaged in a distribution of shares of our Common Stock to engage in market-making activities with respect to these shares. All of the foregoing may affect the marketability of shares of our Common Stock and the ability of any person or entity to engage in market-making activities with respect to shares of our Common Stock.

To the extent required, the Shares to be sold, the names of the persons selling the Shares, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this Prospectus is a part.

We are bearing all of the fees and expenses relating to the registration of the Shares. Any underwriting discounts, commissions or other fees payable to broker-dealers or agents in connection with any sale of the Shares will be borne by the Selling Stockholders. In order to comply with certain states’ securities laws, if applicable, the Shares may be sold in such jurisdictions only through registered or licensed brokers or dealers. In certain states, the Shares may not be sold unless the Shares have been registered or qualified for sale in such state, or unless an exemption from registration or qualification is available and is obtained and complied with. Sales of the Shares must also be made by the Selling Stockholders in compliance with all other applicable state securities laws and regulations.

The Selling Stockholders may agree to indemnify any broker-dealer or agent that participates in transactions involving sales of the Shares against certain liabilities in connection with the offering of the Shares arising under the Securities Act.

We have notified the Selling Stockholders of the need to deliver a copy of this Prospectus in connection with any sale of the Shares.

LEGAL PROCEEDINGS

From time to time, we may be involved in litigation relating to claims arising out of our operations in the normal course of business. We know of no material, existing or pending legal proceedings against us, nor are we involved as a plaintiff in any material proceeding or pending litigation. There are no proceedings in which any of our directors, officers or affiliates, or any registered or beneficial shareholder, is an adverse party or has a material interest that is adverse to our interest.

Beneficial ownership is determined in accordance with the Rule 13d-3(a) of the Securities Exchange Act of 1934, as amended, and generally includes voting or investment power with respect to securities. Except as subject to community property laws, where applicable, the person named above has sole voting and investment power with respect to all shares of our common stock shown as beneficially owned by him.

The beneficial ownership percent in the table is calculated with respect to the number of outstanding shares (61,944,901) of the Company's common stock outstanding as of March 17, 2009.

The term “named executive officer” refers to our principal executive officer, our two most highly compensated executive officers other than the principal executive officer who were serving as executive officers at the end of 2008, and two additional individuals for whom disclosure would have been provided but for the fact that the individuals were not serving as executive officers of the Company at the end of 2008.

DESCRIPTION OF SECURITIES

Pursuant to our articles of incorporation, as amended, we are authorized to issue 100,000,000 shares of common stock, par value $0.01 per share and 10,000,000 shares of preferred stock, par value $0.01 per share. Below is a description of our common stock, shares of which are being offered in this prospectus.

Common stock

Holders of the common stock are entitled to one vote for each share held by them of record on our books in all matters to be voted on by the stockholders. Holders of common stock are entitled to receive dividends as may be legally declared from time to time by the board of directors, and in the event of our liquidation, dissolution or winding up, to share ratably in all assets remaining after payment of liabilities. Declaration of dividends on common stock is subject to the discretion of the board of directors and will depend upon a number of factors, including our future earnings, capital requirements and financial condition. We have not declared dividends on our common stock in the past and we currently anticipate that retained earnings, if any, in the future will be applied to our expansion and development rather than the payment of dividends.

The holders of common stock have no preemptive or conversion rights and are not subject to further calls or assessments. There are no redemption or sinking fund provisions applicable to the common stock. Our articles of incorporation require the approval of the holders of a majority of our outstanding common stock for the election of directors and for other fundamental corporate actions, such as mergers and sales of substantial assets, or for an amendment to our articles of incorporation. There exists no provision in our articles of incorporation or our bylaws that would delay, defer or prevent a change in control of the Company.

DISCLOSURE OF COMMISSION POSITION OF

INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Our directors and officers are indemnified by our bylaws against amounts actually and necessarily incurred by them in connection with the defense of any action, suit or proceeding in which they are a party by reason of being or having been directors or officers of Chembio Diagnostics, Inc. or of our subsidiary. Our articles of incorporation provide that none of our directors or officers shall be personally liable for damages for breach of any fiduciary duty as a director or officer involving any act or omission of any such director or officer. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to such directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

In the event that a claim for indemnification against such liabilities, other than the payment by Chembio Diagnostics, Inc. of expenses incurred or paid by such director, officer or controlling person in the successful defense of any action, suit or proceeding, is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

TRANSACTIONS WITH RELATED PERSONS, PROMOTERS AND CERTAIN CONTROL PERSONS

Lawrence A. Siebert, the president and chairman of the board of directors of Chembio Diagnostics, Inc. (the “Company”) beginning at the time of and after the merger, and the president and chairman of Chembio Diagnostic Systems Inc. since May 2002, held two promissory notes issued by Chembio Diagnostic Systems Inc. One note was issued on August 1, 1999 in the original principal amount of $338,125, bearing interest at a rate of 11 % per annum. The other was issued on April 25, 2001 in the original principal amount of $795,937, bearing interest at a rate of 12% per annum. On May 5, 2004, Mr. Siebert converted the entire outstanding principal amount of the 11% note and $561,875 principal amount of the 12% note into 30 shares of the Company’s Series A Preferred Stock, together with warrants to acquire 1,800,000 shares of common stock at $0.90 per share, pursuant to the Company’s private placement of its Series A Preferred Stock on May 5, 2004. Pursuant to the terms of the original Series A Preferred Stock, the shares of Series A Preferred Stock held by Mr. Siebert were convertible into 1,547,100 shares of the Company’s common stock at $0.60 per share. The remaining debt of $234,062 held by Mr. Siebert was exchanged on May 5, 2004 into 7.80208 shares of the Company’s Series A Preferred Stock, together with warrants to acquire 468,125 shares of common stock at $0.90 per share, pursuant to the terms of the Company’s private placement of its Series A Preferred Stock on May 5, 2004. As of December 31, 2006, $65,287.39 of accrued interest on the debt was also due to Mr. Siebert, but was not accruing interest. As of December 31, 2007, the accrued interest had been repaid. Mr. Siebert also invested $50,000 in the Company’s Series B Preferred Stock private placement pursuant to which he received 1 share of Series B Preferred Stock, which was originally convertible into 81,967 shares of common stock at $0.80 per share, together with a warrant to purchase 77,868 shares of common stock at an exercise price of $0.61 per share.

Mr. Siebert invested $18,700 in Chembio Diagnostic Systems Inc. pursuant to a private placement of convertible notes on March 22, 2004. Mr. Siebert converted the entire principal amount of the note that he received, together with accrued interest thereon, into .942 shares of the Company’s Series A Preferred Stock, together with warrants to acquire 56,520 shares of common stock at $0.90 per share, pursuant to the Company’s private placement of its Series A Preferred Stock on May 5, 2004.

Mr. Siebert prior to March 22, 2004 had either advanced funds to Chembio Diagnostic Systems, Inc. or paid vendors directly on Chembio Diagnostic Systems, Inc.’s behalf. The total amount so paid or advanced totaled $182,181 and was repaid in the fourth quarter of 2006. In addition as of December 31, 2007, all of the accrued interest on the debt due to Mr. Siebert had been paid.

On February 15, 2008, the Compensation Committee approved the reduction of the exercise price to $0.48 per share of each employee stock option award issued under the 1999 Equity Incentive Plan for which the exercise price was greater than $0.48 per share. As a result of this price reduction, the following number of employee stock options awarded to the Company’s officers and directors under the 1999 Equity Incentive Plan qualified for this price reduction: (i) Mr. Siebert: 170,000 options; (ii) Mr. Larkin: 87,500 options; (iii) Mr. Esfandiari: 532,500 options; (iv) Mr. Aromando: 100,000 options; (v) Mr. Ippolito: 15,000 options; (vi) Mr. Bruce: 90,000 options; (vii) Mr. Carus: 252,000 options; (viii) Dr. Meller: 252,000 options; and (ix) Ms. Davis: 180,000 options.

In addition, on February 15, 2008 the Compensation Committee granted, to certain of the Company’s officers, options to purchase the Company’s common stock under the 1999 Equity Incentive Plan as follows: (i) Mr. Siebert received 75,000 options; (ii) Mr. Larkin received 75,000 options; (iii) Mr. Esfandiari received 60,000 options; (iv) Mr. Bruce received 50,000 options; (v) Mr. Ippolito received 50,000 options; and (vi) Mr. Aromando received 25,000 options. The exercise price for each of these options is $0.22 per share, which was the closing market price for the Company’s common stock on February 15, 2008. The options vest on the date of the grant, and each option granted will expire and terminate, if not exercised sooner, upon the earlier to occur of (a) 30 days after termination of the employee’s employment with the Company or (b) the fifth anniversary of the date of grant.

Avi Pelossof, the Company’s Vice President of Sales and Marketing from May 5, 2004 to January 31, 2007, exercised 100,000 options in December 2006 at $0.60 per share, and another 50,000 options in January 2007 at $0.75 per share.

Robert Aromando, the Company’s Executive Vice President of Commercial Operations was hired in May of 2007. In June 2007 in connection with his joining the Company, he was granted options to purchase 100,000 shares of common stock at an exercise price of $0.62 per share. These options will become exercisable one year from the date of grant. As discussed above, on February 15, 2008, the exercise price for these options was reduced to $0.48.

Dr. Gary Meller, a non-employee director of the Company, currently serves as a limited partner and a member of the Advisory Board of Crestview Capital Master LLC, referred to herein as Crestview, which was the lead investor, investing $3 million, in our Series B Preferred Stock private placement in January 2005, and which subsequently invested an additional $1 million in our Series B Preferred Stock private placement in March 2006. Crestview also invested $2 million in our Series C Preferred Stock private placement in September 2006. Details of these transactions are set forth below. Crestview currently is the largest stockholder of the Company.

As referred to above, in January 2005, for a purchase price of $3 million, Crestview acquired 60 shares of our Series B Preferred Stock, and warrants to purchase 4,672,130 shares of our common stock at a warrant exercise price of $0.61 per share.

In March 2006, for a purchase price of $1 million, Crestview acquired 20 shares of Series B Preferred Stock with warrants to purchase 1,557,377 shares of common stock at a warrant exercise price of $0.61 per share. These shares were issued in connection with the Company’s January 2005 private placement as described herein. In September 2006, for a purchase price of $2 million, we issued 40 shares of Series C Preferred Stock to Crestview together with warrants to purchase 625,000 shares of common stock at an exercise price of $1.00 per share.

In January 2007, because of comments from the staff of the SEC concerning the Company’s registration statement No. 333-138266 (the “Prospectus”), Crestview agreed to reduce the number of its shares of common stock covered by the Prospectus to 2,000,000. Crestview also agreed to waive any penalties that the Company would otherwise owe Crestview because of the failure to register all of Crestview’s shares in the Prospectus. In consideration for this waiver, the Company agreed that, upon request by Crestview, the Company will file one or more registration statements with the SEC in order to register the resale of other shares beneficially owned by Crestview. The cost of any such registration statements shall be borne by the Company.

In addition to Crestview’s $2,000,000 investment in the Company’s September 2006 private placement of Series C Preferred Stock, the Company also received an investment of $2,000,000 on that date from Inverness Medical Innovations, Inc. (“Inverness”). At that time, a Certificate of Designation for the Series C Preferred Stock was filed with the Secretary of State of Nevada reflecting the agreed upon conversion price of $0.85 per share of common stock. This private placement of Series C Preferred Stock was completed on October 5, 2006, and it raised an aggregate of $8,150,000 (including the $2,000,000 invested by each of Crestview and Inverness). During the period between September 29, 2006 and October 5, 2006, we requested the assistance of Crestview and others in identifying prospective investors for us. On October 3, 2006, a Crestview representative informed Mr. Siebert of a conversation he had earlier that day with a fund manager who indicated that his fund would be interested in investing a substantial amount in the offering, but only at a conversion price of no more than $0.80.

At a board of directors meeting on October 4, 2006, Mr. Siebert expressed his recommendation that the board approve lowering the conversion price to $0.80 in order to be able to obtain the additional funds. The board discussed the $1,300,000 promissory note bridge financing which had been completed in June 2006, the noteholders who expected to convert their notes into Series C Preferred Stock, and the restrictions on future equity sales by the Company in the bridge financing purchase agreement that necessitated finalizing promptly the Series C Preferred Stock offering. After discussion to approve the funding, the motion was approved unanimously, with the exception of Gerald Eppner who abstained. Mr. Eppner stated that he understood the benefits of the economics of the transaction and the Company’s need to proceed so quickly, but that he did not wish to vote in favor.

At a board meeting held on October 11, 2006, the board members discussed the Series C Preferred Stock private placement. Mr. Eppner indicated that in his view it would be desirable to review the sequence of events in this transaction to assure proper guidelines for corporate governance and to determine if disclosure or other issues needed to be considered. At a board meeting held on October 26, 2006, it was discussed that a subcommittee of the audit committee, whose members would be Mr. Eppner and Alan Carus, would review certain issues related to the Series C Preferred Stock private placement.

The first meeting of the audit committee to review the Series C Preferred Stock offering was held on October 27, 2006. The audit committee decided it would review the role of Crestview in the Series C Preferred Stock offering, Crestview’s status as a possible control person, the role of Dr. Gary Meller in the offering and his relationship with Crestview, and whether the audit committee should recommend new corporate governance procedures to be implemented or any action to be taken by the Board. The audit committee utilized legal counsel to assist in its review. The audit committee held seven meetings during the period from October 27, 2006 to January 10, 2007. Messrs. Carus and Eppner attended all of the meetings. Mr. Carus concluded that: (i) he was satisfied with the review, and (ii) although with fewer time constraints, there could have been more deliberation regarding the change in the conversion price, he believed there was no inappropriate conduct, that the Company had not suffered any damage and that the matter should be closed. Mr. Eppner stated his concerns that: (i) Crestview is an affiliate of the Company, (ii) there was no participation by the Company in the reduction in the conversion price from $0.85 to $0.80, (iii) although he agreed with Mr. Carus that the $0.80 price may have been acceptable to the Company, it was not as good as a higher price, (iv) Mr. Siebert should not have allowed this to happen, and that because he did, it was evidence of control by Crestview, and (v) disclosure of the review of the audit committee should be made in a registration statement that was to be filed shortly thereafter.

On January 30, 2007, Gerald Eppner resigned from his position as a director of the Company, effective immediately. At the time of his resignation, as additional consideration of his time and efforts as a member of the board of directors, the Company granted Mr. Eppner $20,000, and caused his outstanding unvested stock options to become vested immediately. In his resignation letter, Mr. Eppner stated that he did not resign due to any disagreement with the Company, or because of any matter relating to the Company's operations, policies or practices.

On December 19, 2007 (the “Closing Date”), amendments to the governing documents for the Company’s Series A, Series B and Series C Convertible Preferred Stock (collectively, the “Preferred Stock”) and for certain warrants and options (collectively, the “Non-Employee Warrants”), not including options or warrants issued to employees or directors in their capacity as such (these actions collectively, the “Plan”), were approved by the Company and the requisite percentages of the holders of the Preferred Stock and of the Non-Employee Warrants. Subsequent to these amendments, all shares of Preferred Stock were converted to common stock and certain of the Non-Employee Warrants were exercised, including the following: Mr. Siebert’s 38.74442 shares of Series A Preferred Stock were converted into 2,421,526 shares of common stock at $0.48 per share, his 1.08545 shares of Series B Preferred Stock were converted into 113,067 shares of common stock at $0.48 per share, and Mr. Siebert purchased 337,500 shares of common stock through the exercise of warrants at an exercise price of $0.40 per share, for a total of $135,000 in cash; Mr. Larkin on December 19, 2007 pursuant to the Plan converted .50392 shares of his Series A Preferred Stock into 37,794 shares of common stock at $.40 per share, in addition he received 369 shares of common stock as payment of dividends on the series A preferred. He also received 3,050 shares of common stock in the exercise of warrants pursuant to the Plan at $.40 per share, or a total of $1,220 in cash, Inverness’ 40 shares of Series C Preferred Stock were converted into 4,166,666 shares of common stock, and Inverness exercised all of its Series C Warrants to purchase a total of 625,000 shares of common stock for an aggregate purchase price of $250,000 and Crestview’s 82.32274 shares of Series B Preferred Stock were converted into 10,290,342 shares of the Company’s common stock, Crestview’s 40 shares of Series C Preferred Stock were converted into 4,166,666 shares of common stock, Crestview exercised a portion of its Series B Warrants to purchase a total of 60,451 shares of common stock for an aggregate purchase price of $24,180.40, and Crestview exercised all of its Series C Warrants to purchase a total of 625,000 shares of common stock for an aggregate purchase price of $250,000.

In June 2008, pursuant to the Plan (see above), Mr. Siebert, exercised 2,205,731 warrants, on a cashless basis, into 332,940 shares of common stock, Mr. Larkin exercised 27,436 warrants, on a cashless basis, into 4,141 shares of common stock, and Crestview exercised 6,169,055 warrants, on a cashless basis, into 931,177 shares of common stock.

During the quarter ended December 31, 2008, Inverness notified the Company that Inverness had entered into a contract with Bio-Rad Laboratories, Inc. (“Bio-Rad”) for royalties on Bio-Rad’s patent for the detection of HIV-2 antibodies. The agreement also provided for Inverness to pay past royalties. The agreements between the Company and Inverness provide that the Company is to share in this expense and as such Inverness requested it be reimbursed for the Company’s share of past royalties. The Company negotiated with Inverness that this liability is to be paid from future revenues over approximately the next 18 months. In addition Inverness agreed to allow Chembio to pay its royalty obligation to Inverness on Chembio’s sales to third parties in the same way and over the same period.

General

Chembio Diagnostics, Inc. (referred to collectively with its subsidiaries as the “Company”) and its subsidiaries develop, manufacture and market rapid diagnostic tests that detect infectious diseases. The Company’s main products presently commercially available are three rapid tests for the detection of HIV antibodies in whole blood, serum and plasma samples, all of which employ lateral flow technology, and two of which were approved by the FDA in 2006. In addition, we have a fourth rapid HIV test, developed on our patented Dual Path Platform (DPP®) technology, for the detection of antibodies to HIV in oral fluid samples, as well as whole blood, serum and plasma samples. The products which employ lateral flow technology are manufactured and sold under a non-exclusive license we have from Inverness Medical Innovations, Inc. (“Inverness”), which is also our exclusive marketing partner for the FDA-approved products in the United States (as well as Europe and Asia for the product that is known as the “barrel” format product) under its Clearview® brand. Inverness launched its marketing of these products in the United States in February 2007. Chembio’s two HIV STAT-PAK® rapid HIV tests (in cassette and dipstick formats) are marketed outside the United States through different partners and channels under our license from Inverness.

On March 13, 2007, we were issued United States patent #7,189,522 for our Dual Path Platform (DPP®) rapid test system. Additional patent protection for DPP® is pending worldwide. DPP® enables Chembio to participate in the growing point–of-care diagnostics market with a patent-protected point-of-care platform technology. DPP® devices enable the development of products whose performance we believe exceeds that of comparable tests developed with lateral flow technology. As stated above we have completed development of an oral fluid HIV test on this new platform and are currently pursuing the commercialization of this product in several markets. We have also developed and/or are developing several other products on DPP®. We believe that DPP® provides significant advantages as a point-of-care platform particularly where challenging sample matrices, such as oral fluid, are involved, or where multiplexing is desired. We are developing all of our new products using this platform. Our strategy for the development of this platform technology is also dual; we have entered and are seeking to enter exclusive collaborations with large marketing partners for whom we will develop and manufacture products on the DPP® and we are developing our own products that we may choose to market through selected distribution partners either under a Chembio, DPP® or other brand.

Our products are sold to medical laboratories and hospitals, governmental and public health entities, non-governmental organizations, and medical professionals. Our products are sold either under our DPP®, STAT-PAK® or SURE CHECK® registered trademarks and/or the private labels of our marketing partners, such as is the case with the Inverness Clearview® label for our rapid HIV tests in the United States.

Rapid HIV Tests

The major component of our revenue growth in 2008 was increased sales of our rapid HIV tests and related components. A large percentage of individuals that are HIV positive worldwide are unaware of their status. Part of the reason for this is that even those that do get tested in public health settings will often not return or call back for their test results if samples have to be sent out to a laboratory which can take at least several days to process. The increased availability, greater efficacy and reduced costs for anti-retroviral treatments (ARVs) for HIV is also having a tremendous impact on the demand for testing, as the stigma associated with the disease is lessened, and the ability to resume normal activities is substantially improved, providing a positive message to those potentially infected. All four of our rapid HIV tests are qualitative “yes/no” tests for the detection of antibodies to HIV 1 & 2 with results available within approximately 15 minutes. The tests differ principally only in the method of sample collection and test procedure, flexibility with different sample types, and cost of manufacture. Prior to our agreement with Inverness, our rapid HIV tests had been marketed under either our SURE CHECK® or STAT-PAK® trademarks. Pursuant to our agreement with Inverness Medical Innovations, Inc., the SURE CHECK® product (which incorporates a proprietary barrel format) is now being marketed by Inverness as Clearview® Complete HIV 1/2 and the cassette format of our HIV 1/2 STAT-PAK (we also have a third product known as HIV 1/2 STAT-PAK dipstick) is now being marketed by Inverness in the United States as Clearview® HIV 1/2 STAT-PAK®. We continue to market our STAT-PAK® cassette and dipstick outside the United States through other marketing channels. In addition, in 2008 we amended the agreement with Inverness, which previously had global exclusivity for the barrel format product, to a non-exclusive in Africa and Latin America. We will begin to market our DPP® oral fluid test globally (including in the United States) as we establish required regulatory clearances and authorizations, which we expect to receive during this year for certain markets in the developing world, though there is no assurance that this will occur.

Regulatory Status:

Rapid HIV Tests

The FDA approved our Pre-Market Applications (hereinafter “PMA”; see “Governmental Regulations” and Glossary) for our SURE CHECK HIV 1/2 (and also now Inverness’ Clearview® Complete HIV 1/2 ) and HIV 1/2 STAT-PAK (now Inverness’ Clearview® HIV 1/2 STAT-PAK in the United States only) products on May 25, 2006. A Clinical Laboratory Improvement Act (“CLIA”) waiver was granted by the FDA for the HIV 1/2 STAT-PAK on November 20, 2006. Labeling changes to the Inverness Clearview® brands for both products were approved during the first quarter of 2007. CLIA waiver for the Clearview® Complete HIV 1/2 was granted on October 22, 2007. CLIA waiver is required in order to market the products for use in hospital emergency rooms, public health clinics and physicians’ offices, where the level of training is traditionally less than the training at clinical laboratories and laboratories in hospitals. These settings constitute the largest portion of the available market for our products. Our third lateral flow rapid HIV test, HIV 1/2 STAT-PAK Dipstick and our DPP® oral fluid HIV test, though not FDA approved, qualify under FDA export regulations to sell, subject to any required approval by the importing country, to customers outside the United States. The dipstick product is our most competitively priced version of our three rapid HIV tests, and was designed primarily for resource-constrained, donor-funded markets that have large test volume needs. Although we have received approval from a number of potential importing countries for three of our lateral flow HIV tests, Brazil, Mexico, Nigeria, Ethiopia and Uganda are the countries in which we have realized significant sales. As a result of favorable evaluations of our HIV 1/2 STAT-PAK and HIV 1/2 STAT-PAK Dipstick products by the World Health Organization (the “WHO”), these products are qualified for procurement by programs funded by the United Nations and their partners’ programs. All three of our lateral flow HIV tests have qualified for procurement under the President’s Emergency Plan for AIDS Relief (“PEPFAR”). During the first quarter of 2009 we submitted our oral fluid DPP® HIV 1/2 test, to these same agencies for inclusion in these programs. We also have other evaluations ongoing for this new product and anticipate commencement of clinical trials in the United States in support of a PMA during this year.

Partners Involved in Marketing Our Products

On September 29, 2006 we executed marketing and license agreements with Inverness. These agreements provide for the marketing of our rapid HIV tests in the United States; the agreements also grant us a license to Inverness’ lateral flow patents that may be applicable to certain of our other products, including those that we had under development at the time of the grant. As part of these agreements we also settled litigation that had been ongoing with another company, StatSure Diagnostics, Inc., relating to the proprietary barrel device that is incorporated into our Sure Check® HIV 1/2 product, which is also marketed exclusively as Inverness Clearview® Complete HIV 1/2 in the United States, Europe and Asia.

We have appointed distributors internationally so that we are positioned to service those markets. Our focus is on those countries that have received or will receive funding commitments for HIV prevention and treatment, of which rapid HIV testing is an essential part. The most significant program globally that funds HIV testing is the United States PEPFAR program, which primarily is focused in 15 countries in sub-Saharan Africa that are at the epicenter of the disease. During 2008 we shipped approximately 2.4 million test kits to Nigeria, 1.6 million test kits to Uganda, and approximately 600,000 test kits to Ethiopia, or a total of approximately 4.6 million tests, mostly through the PEPFAR procurement agency known as the Partnership for Supply Chain Management (“PSCM”). Lesser volumes were shipped to several other countries in Asia, and Latin America. We also shipped HIV test kit components to the Oswaldo Cruz Foundation for the manufacture of tests in Brazil pursuant to our 2004 technology transfer agreement.

Effective in January 2009, Nigeria changed from a parallel testing algorithm to a serial algorithm, and in this change our test’s designation in two of their new protocols was changed to that of a confirmatory test and a tie-breaker test in the third protocol. This designation has resulted in a dramatic reduction of sales to this country which decrease we anticipate will likely continue for at least several months. During 2008, the implementation of our HIV 1/2 STAT-PAK® as the confirmatory test in Ethiopia’s serial testing algorithm resulted in significantly increased sales to that country, which increases we anticipate may continue during 2009. We do not presently anticipate however that the increased sales in Ethiopia will in any case fully offset the decrease in Nigeria.

We are pursuing new opportunities for distribution of our existing lateral flow HIV tests and new DPP® oral fluid HIV test in a number of markets globally. As stated earlier, during 2008 we amended our agreement with Inverness so that we may now market the barrel product under Chembio’s trademark, SURE CHECK® HIV 1/2 directly throughout South America and Africa, subject to the payment of royalties to Inverness in accordance with our license to their lateral flow patents.

OTHER RAPID TESTS

We also have commercially available lateral flow tests for Chagas Disease and also a line of tests for the detection of tuberculosis in humans and certain animal species. However, these products represented less than 4% of our product revenues during 2008 and are not part of the central focus of our current business and growth strategy.

Our Rapid Test Technologies

All of our commercially available current products employ either in-licensed lateral flow technology or our own patented Dual Path Platform (DPP®) technology.

Lateral flow technology involves a sample flowing from the point of application on a test strip to provide a test result, indicated with a labeling reagent that allows the result to be visually or otherwise detected, on a portion of a strip downstream from either the point of application of the sample. Lateral flow technology is well established and widely applied in the development of rapid diagnostic tests. The functionality of our lateral flow tests is based on the ability of an antibody to bind with a specific antigen (or vice versa) and for the binding to become visible through the use of the colloidal gold and/or colored latex that we use in our products. The colloidal gold or the colored latex produces a colored line if the binding has occurred (the test line), in which case it means there has been a reactive or positive result. In any case, a separate line (the control line) will appear to confirm that the test has been validly run in accordance with the instructions for use.

On March 13, 2007, we were issued United States patent number #7,189,522 describing a Dual Path Immunoassay system which we believe provides several advantages over lateral flow technology for certain applications (See “Intellectual Property”). The Dual Path Platform technology, or DPP®, uniquely provides for the sample application and migration toward the test zone area to be from an independent strip. This system enables improved sample control, multiplexing and certain other advantages. DPP® is providing the Company with significant new product development and licensing opportunities, and we are devoting all of our research and development efforts toward these programs.

The sensitivity of a test indicates how strong the sample must be before it can be detected by the test. The specificity of a test measures the ability of the test to analyze, isolate, and detect only the matters targeted by the test. The sensitivity and specificity of our rapid HIV tests during our clinical trials undertaken in connection with our FDA PMAs were 99.7% and 99.9%, respectively. Both lateral flow technology and DPP® allow the development of accurate, low cost, easy-to-perform, single-use diagnostic tests for rapid, visual detection of specific antigen-antibody complexes on a test strip. This format provides a test that is simple (requires neither electricity nor expensive equipment for test execution or reading, nor skilled personnel for test interpretation), rapid (turnaround time approximately 15 minutes), safe (minimizes handling of potentially infected specimens), non-invasive (requires 5-20 micro liters of whole blood easily obtained with a finger prick, or alternatively, serum or plasma), stable (24 months at room temperature storage in the case of our HIV tests), and highly reproducible.

Our HIV tests are qualitative (reactive/non-reactive) tests. We have developed proprietary techniques that enable us to achieve high levels of sensitivity and specificity [see definition above] in our diagnostic tests using our proprietary colloidal gold conjugates and buffer systems. These techniques include the methods we employ in manufacturing and fusing the reagents with the colored latex, or colloidal gold, blocking procedures used to reduce false positives, and methods used in treating the materials used in our tests to obtain maximum stability and resulting longer shelf life. We also have extensive experience with a variety of lateral flow devices, including the sample collection device used in our SURE CHECK rapid HIV test which eliminates the need for transferring finger-stick whole blood samples from the fingertip onto a test device, because the collection of the sample is performed within a tubular test chamber that contains the lateral flow test strip. The whole blood sample is absorbed directly onto the test strip through a small opening in one end of the test chamber and an absorbent pad positioned just inside this same end of the test chamber.

During 2007 and 2008 we entered collaborations with companies that have developed hand held and desktop readers that can objectively measure, quantify, record and report test results. Certain of the products we have and/or are developing for our customer in Brazil, the Oswaldo Cruz Foundation, will incorporate some of these readers, and we are developing other products that may be used with or will require use of a reader.

Target Market

Rapid HIV Tests

The marketing of our FDA-approved and CLIA-waived rapid HIV tests in the United States was launched by Inverness during the first quarter of 2007, and we estimate to have approximately a 10% share of the U.S. rapid HIV test market. In the United States, the need for rapid HIV tests has been developing first in the public health and hospital emergency room segments, and also in the physicians’ office laboratories. Of the estimated 25-30 million HIV tests performed in clinical settings in the United States, rapid HIV tests now account for approximately 20-25% of this market, or approximately 5-6 million tests of this total. We believe that the total number of HIV tests will continue to grow, and that the share available to rapid HIV tests will also grow.

The pace of the implementation of recommendations that were made in late 2006 by the United States Centers for Disease Control (“CDC”) for routine HIV testing of all individuals between the ages of 13 and 64 will be a major factor in the rate of growth of the rapid HIV testing market in the United States. Endorsement of these recommendations by opinion leaders in the professional medical community are gradually helping to increase the demand for HIV testing in the United States. In addition, the revelation in a study disclosed in 2008 by CDC that annual new HIV cases in the US, which disproportionately impact African-Americans, had been under-reported for years by approximately 40%, underscored the need for improved prevention efforts in the United States. Although the most recent efforts to increase federal funding for STD prevention in the federal stimulus package were unsuccessful, we still believe that there is a good prospect that the current Congress and Administration will seek to increase these programs through other legislative appropriations.

In the international market, PEPFAR, the large United States funded international AIDS relief program focused on fifteen countries, was reauthorized last year for up to $48 billion for FY2009-2012 (up from $15 billion in 2004-2008); the appropriation for 2009 is approximately $5.5 billion, of which approximately 12% or $900 million is allocated to the Global Fund, the other large international program created in 2001 to combat HIV/AIDS, TB and Malaria. PEPFAR, The Global Fund and other global initiatives have succeeded in making life-saving treatments available now to well in excess of one million individuals. We believe that this is likely to have the effect of further encouraging more people to get tested, because with the availability of treatment, there is a clear reason to be tested. Other programs such as UNAIDS are significant participants in the global effort to prevent further transmission and save the lives of those already infected, as well as care for their families that are impacted.

Marketing Strategy

Our marketing strategy is to:

Support, review and assess the marketing and distribution efforts of our rapid HIV tests by Inverness Medical Innovations, Inc. Inverness, which is a leading marketer of point-of-care diagnostic products, has significantly expanded its distribution footprint since we signed our agreement with Inverness, and we believe that this will enhance opportunities for Inverness to market our rapid HIV tests. In particular, Inverness has been very active in acquiring point-of-care product lines serving hospital emergency rooms and physicians’ offices.

·	Leverage our DPP® intellectual property and regulated product development and manufacturing experience to create new collaborations where Chembio can be the exclusive development and manufacturing partner with world class marketing partners.

·	Develop a small number of Chembio or DPP® branded products that capitalize on the advantages of this newly patented point-of-care technology and select distribution partners for such products.

Competition

The diagnostics industry is a multi-billion dollar international industry and is intensely competitive. Many of our competitors are substantially larger and have greater financial, research, manufacturing and marketing resources.

Industry competition in general is based on the following:

·	Scientific and technological capability;

·	Proprietary know-how;

·	The ability to develop and market products and processes;

·	The ability to obtain FDA or other required regulatory approvals;

·	The ability to manufacture products that meet applicable FDA requirements, (i.e. FDA’s Quality System Regulations) (see Governmental Regulation section);

·	The ability to manufacture products cost-effectively;

·	Access to adequate capital;

·	The ability to attract and retain qualified personnel; and

·	The availability of patent protection.

We believe our scientific and technological capabilities and our proprietary know-how relating to our in-licensed lateral flow technology rapid tests and to our proprietary know-how related to our patented dual path platform technology, particularly for the development and manufacture of tests for the detection of antibodies to infectious diseases such as HIV, are very strong.

Our ability to develop and market other products is in large measure dependent on our having additional resources and/or collaborative relationships. Some of our product development efforts have been funded on a project or milestone basis. We believe that our proprietary know-how in lateral flow technology and in our dual path platform technology has been instrumental in our obtaining the collaborations we have and that we continue to pursue. We believe that the patent protection that we have with our Dual Path Platform enhances our ability to develop more profitable collaborative relationships and to license out the technology.

We believe our regulatory certifications are also a strong asset for developing new products and collaborations. There are only two companies besides Chembio that have approved PMA’s for lateral flow rapid tests, all HIV tests: Trinity Biotech (Ireland) and Orasure Technologies, Inc. (PA). We believe that this is a significant competitive advantage when considering new products and collaborations. During 2006 and 2007 we obtained CLIA waivers for each of our FDA PMA approved HIV tests. These products therefore represent two of the four CLIA-waived rapid HIV tests. During 2007 and 2008 we received facility and product licenses from the USDA, became certified under ISO 13.485, and received our initial CE mark (for our Chagas product). We anticipate receiving CE marks for our HIV products during the first half of 2009.

Our access to capital is much less than that of several of our competitors, and to the extent we would need to access large amounts of capital, this is a competitive disadvantage. We believe however that our access to capital is likely to increase if we continue our trend of improved operating results, and in the meantime we are focused on minimizing our capital requirements. Establishment of strategic collaborations for our DPP® technology also may provide us with access to funding that is potentially less dilutive or non-dilutive. The simplification of our capital structure that was completed in December 2007 should also improve our access to capital (See Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview).

To date, we believe we have been competitive in the industry in attracting and retaining qualified personnel. Because of the greater financial resources of many of our competitors, we may not be able to compete effectively for the same individuals to the extent that a competitor uses its substantial resources to attract any such individuals. Also, in order to control costs and conserve resources, we have implemented layoffs and salary reductions that larger companies with greater resources may not need to implement.

We have been able to obtain patent protection by entering into licensing arrangements for reagents and lateral flow technologies. The March 2007 issuance by the United States Patent & Trademark Office of our Dual Path Platform™ patent gives us our first patent protection for our own rapid test platform, which we believe enhances our competitive position. Additional protection of this intellectual property is pending worldwide.

Competitive factors specifically related to our HIV tests are product quality, delivery, sensitivity, specificity, ease-of-use, shelf life and price. Other factors can be sample size required, the presence of a true IgG control, and time to result. During the last few years, the competitive features of certain products produced by some international competitors have improved. Most of these companies, whose products are not and in most cases probably could not be FDA approved, typically have substantially lower costs of labor, regulatory approval and compliance, and intellectual property (if any) as compared with Chembio. Price has become an increasingly important factor since U.S. procurement rules still operate under a waiver of Buy America provisions, described below. Also, as described below, in most of the donor-funded markets in the developing world technical committees controlled by host governments are empowered to make final decisions as to which products will be used in screening programs. The leading competitors in the international rapid HIV test market are Trinity Biotech (Ireland), Inverness (U.S.) and Standard Diagnostics (Korea). Uni-Gold® HIV, marketed by Trinity Biotech of Ireland and Determine®, marketed by Inverness Medical, are the market leaders in the developing world, particularly sub-Saharan Africa, which is where most of the funding for rapid HIV tests is being allocated from donor funded programs such as PEPFAR. Neither the Trinity or Inverness products are FDA-approved, although Trinity does manufacture in Ireland an FDA-approved rapid HIV test, Uni-Gold Recombigen, for marketing in the United States. Inverness’ Orgenics subsidiary in Israel also has a rapid HIV test, Double-Check Gold, as does its subsidiary in China, ABON; neither of these products is FDA-approved. As such, while Inverness is our exclusive marketing partner in the United States, it is also a principal competitor to our rapid HIV tests outside the United States. Furthermore, in 2006 Trinity Biotech settled litigation with Inverness, and as part of that settlement it committed to have ABON, an Inverness subsidiary, to manufacture all of Trinity’s Uni-Gold® HIV products primarily for the African market. Standard Diagnostics of Korea also has a low-cost product that is very competitive against each of the other competitors in the developing world. There are a number of additional competitors, including several based in China and India of varying quality, that produce competitive rapid HIV tests.

Under a now long-established waiver of Buy America provisions, products procured with US taxpayer funds need not be FDA approved or even made in the US so long as they meet reduced quality standards as compared to what would be required for an FDA approved product. Under the waiver guidelines, all manufacturers are invited by PEPFAR to be considered for procurement with United States taxpayer funds. The waiver, which was initially made available because of a dearth of suitable US-made or FDA approved products when PEPFAR was originally authorized, has continued even though there are now several products, including Chembio’s, that are FDA approved. Also, in addition to competing against approximately thirty non-FDA approved, non-US made products that can be purchased under U.S. procurement rules, in order to realize sales in the markets where the donor (mostly U.S.) funds are allocated, the product must additionally be selected by a country’s ministry of health or their designees to be part of a national testing protocol or “algorithm”. The algorithms typically use multiple rapid tests in sequence or in parallel to screen and confirm patients at the point-of-care and are increasingly allowing for multiple tests to be qualified in these algorithms. Chembio’s sales in Africa and certain other markets are therefore based on the fact that its test has been one of those selected. A product’s designation in a donor-funded country’s algorithm is largely followed by most of the implementing agencies and organizations, resulting in the selection process being critical to participation in donor funded procurements in such market, and limiting the impact of marketing activities once these selections have been made. The selection process in each of these countries is not predictable and is based upon a number of factors, including but not limited to product performance, price, and supply chain.

In the developed world, particularly the United States and Europe, the competitive landscape and market dynamics are quite different. Due to the costs of and quality system requirements associated with US FDA regulatory approval, there are currently only two companies besides Chembio that have products that are both FDA PMA-approved and also CLIA-waived: Orasure Technologies (Bethlehem, PA) with OraQuick®, and Trinity Biotech Ltd. (Ireland) with Uni-Gold® Recombigen. The regulatory costs for FDA approval and fewer number of products in turn results in very different (higher) pricing in the US market as compared with the developing world, with prices in the US averaging $8-12 per test to end user. This compares to approximately $1.00 per test in the developing world. As the requirements for the PMA and CLIA waiver are difficult, costly, risky and time-consuming, particularly relative to the size of the market, and because such approval is not required for participation in PEPFAR under the above-described waiver guidelines, we do not anticipate that Inverness has any plan to submit any of its products produced outside the U.S. to the FDA. Further, our agreements with Inverness provide that in the event one of those submissions is made (or if Inverness acquires a competitive product in the United States), we have the right to terminate our agreement with Inverness or make Inverness’ marketing rights non-exclusive. In either case, we would retain a license under the Inverness lateral flow patents to market the products under a Chembio brand and/or through third party distribution partners.

Orasure has an estimated market share in the U.S. of approximately 70% with its Oraquick ® product. This product’s main advantages are that it was the first test to market and also that, at least for certain market segments (primarily public health), it can be performed with oral fluid samples, as compared with only blood samples, which is the case for our products as well as Trinity’s. The main disadvantage of the Orasure product is its relatively higher price. Also, Orasure’s claimed sensitivity with oral fluid samples is lower than with blood samples, and combined with some limited reports of performance (false positive) problems on oral fluid samples, this has created some opportunities for Inverness with our product, as well as for Trinity.

Orasure markets its products directly through its own sales organization to the public health market, has made a significant investment in that market, and has nearly 100% of the three largest states in this market (New York, California and Florida) that together constitute the majority of public health HIV testing in the US. For the hospital market segment Orasure had an exclusive marketing arrangement with Abbott Diagnostics, but as of January 2009 they terminated this agreement and are expanding their direct sales organization to market directly to the hospital market segment as well. Trinity also relies on its own sales force to market its product, and does not have any other rapid tests to sell to distributors. The Uni-Gold product that is marketed by Trinity accounts for an estimated 10% of the market. This product does not detect HIV-2, while our products and Orasure’s both do. Though HIV-2 is a rare strain of HIV, it is an advantage to be able to detect, though there is a cost of 15% of Net Sales to the license for this claim. Trinity’s product also requires a much larger sample size, and does not have a true IgG control. This means that a control line, which is intended to confirm that the test procedure has been performed correctly, will appear on their product so long as any liquid material is applied to its sampling area; Chembio’s (and Orasure’s) control line will appear only if a biological sample is applied. The shelf life of our HIV products is 24 months, which is twice that of both the Uni-Gold and Orasure products.

We believe that Inverness, as a leading marketer of a broad range of point-of-care tests sold into all U.S. market segments, has a superior marketing organization as compared to either of our U.S. market competitors who are much smaller than Inverness. Inverness has made a significant investment in its launch of our products, in the training of a large marketing organization in the US, and in the acquisition of complementary product lines and sales organizations. For example, Inverness has significantly augmented its access to emergency room departments in hospitals through its acquisition of Bio-Site, which was the leading company in point-of-care tests for cardiac monitoring, and whose sales force can now add our product to its product portfolio for this important market segment. We believe that this is an example of the distribution advantages of our marketing partner.

Chembio’s HIV Tests

One of our two product formats, the “barrel” format now marketed by Inverness as Clearview® Complete HIV 1-2, is a unique product format inasmuch as it is a unitized product, meaning that all components necessary to perform a single test are contained in a single pouch. This “barrel” format provides for a proprietary method of collecting finger-stick whole blood samples that eliminates the need for the step that all other devices require of transferring the sample from the fingertip to the sample well of the test. Also, the buffer solution in the barrel format is in a unitized vial that is pierced by the barrel tip to initiate the sample migration up the test strip contained inside the “barrel”, and thereby creates a closed system that helps to minimize possible exposure to potentially infectious samples.

Our other FDA PMA approved rapid HIV test, marketed by Inverness as Clearview® HIV 1-2 STAT PAK®, is a rectangular-shaped lateral flow plastic cassette format test wherein the sample is transferred from the sample source (finger tip in the case of finger-stick whole blood samples) to the sample port in the cassette by means of a transfer loop. Though this step is not required in the barrel format, the cassette is less costly to manufacture, is a more familiar format to customers that have performed other standard design lateral flow tests, and is a more flexible format that utilizes the same procedure for all approved sample matrices (venous whole blood, finger-stick whole blood, serum and plasma). To date this format has accounted for almost all of the sales we have had through Inverness. However this is in part due to the fact that the barrel format was not CLIA waived until October 2007, approximately a year later than the cassette product, and we anticipate more sales of this product in the future, though still less than the cassette.

Research and Development

During 2008 and 2007, $2.6 million and $1.9 million, respectively, were spent on research and development activities. Substantially all of our new product development activities involve employment of our Dual Path Platform (DPP®) technology for which we were awarded a U.S patent in 2007. We believe that this platform enables us to pursue many new product development and licensing opportunities. The DPP® technology can provide improved features on certain tests developed with it that include higher sensitivity, earlier detection, improved performance with more challenging sample types (such as oral fluid), and the improved ability to detect multiple analytes (multiplexing) in one test device.

During 2008 we made substantial progress in developing a portfolio of products based on the DPP® technology. These activities include completing development of certain products and making significant progress toward the development of additional products. These activities are further explained in Part II Item 7.

Regulatory Activities

We continue to make progress on obtaining a Community European (CE) marking for our products to indicate conformity with European Union health, safety and environmental requirements. We have submitted the HIV 1/2 STAT-PAK® technical file to our notified body and should complete all required steps for CE Marking of this product during the second quarter of 2009. Under our agreement with Inverness we are to obtain a CE Marking for the Clearview® Complete HIV 1/2. We are prepared to submit the technical file for this product on behalf of Inverness once we received final proposed labeling from Inverness.

We are also pursuing registrations of our lateral flow and DPP® HIV products in a number of other jurisdictions, and also pursing registrations with the USDA of additional claims for our veterinary tuberculosis products.

During 2008 we received FDA approval for the lowering of the age limits that the tests are approved for from 18 years to 13 years of age. This lowering of the lower age limit put our approved product claims in line with the 2006 CDC recommendations for routine test of all individuals between the ages of 13 and 64, and we believe that this additional marketing claim for the product will assist Inverness in certain market opportunities with our products.

Employees

At December 31, 2008, we employed 114 people, including 110 full-time employees. Effective May 2006, we entered into an employment agreement with Lawrence Siebert, President and Chairman. Effective March 2007, we entered into an employment agreement with Javan Esfandiari, Executive Vice-President of Research and Development.

Governmental Regulation

The manufacturing and marketing of the Company’s existing and proposed diagnostic products are regulated by the United States Food and Drug Administration (“FDA”), United States Department of Agriculture (“USDA”), certain state and local agencies, and/or comparable regulatory bodies in other countries. These regulations govern almost all aspects of development, production and marketing, including product testing, authorizations to market, labeling, promotion, manufacturing and record keeping. The Company’s FDA and USDA regulated products require some form of action by each agency before they can be marketed in the United States, and, after approval or clearance, the Company must continue to comply with other FDA requirements applicable to marketed products, e.g. Quality Systems (for medical devices). Failure to comply with the FDA’s requirements can lead to significant penalties, both before and after approval or clearance.

Most point-of-care diagnostic products are regulated as medical devices by the FDA Centers of Device and Radiological Health, though some are regulated by the FDA Center of Biologics Evaluation and Research. There are two review procedures by which medical devices can receive FDA clearance or approval. Some products may qualify for clearance under Section 510(k) of the Federal Food, Drug and Cosmetic Act, in which the manufacturer provides a pre-market notification that it intends to begin marketing the product, and shows that the product is substantially equivalent to another legally marketed product (i.e., that it has the same intended use and is as safe and effective as a legally marketed device and does not raise different questions of safety and effectiveness). In some cases, the submission must include data from human clinical studies. Marketing may commence when the FDA issues a clearance letter finding such substantial equivalence. An applicant must submit a 510(k) application at least 90 days before marketing of the affected product commences. Although FDA clearance may be granted within that 90-day period, in some cases as much as a year or more may be required before clearance is obtained, if at all.

If the medical device does not qualify for the 510(k) procedure (either because it is not substantially equivalent to a legally marketed device or because it is required by statute and the FDA’s implementing regulations to have an approved application), the FDA must approve PMA application before marketing can begin. PMA’s must demonstrate, among other matters, that the medical device provides a reasonable assurance of safety and effectiveness. A PMA application is typically a complex submission, including the results of non-clinical and clinical studies. Preparing a PMA application is a much more expensive, detailed and time-consuming process as compared with a 510(K) pre-market notification. Once a PMA has been submitted, the FDA is required to review the submission within a statutory period of time. However, the FDA’s review may be, and often is, much longer, often requiring one year or more, and may include requests for additional data. The Company has approved PMAs for the two rapid HIV tests now marketed by Inverness Medical as Clearview® Complete HIV 1-2 and Clearview® HIV 1-2 STAT PAK®.

Every company that manufactures medical devices distributed in the United States must comply with the FDA’s Quality System Regulations. These regulations govern the manufacturing process, including design, manufacture, testing, release, packaging, distribution, documentation and purchasing. Compliance with the Quality System Regulations is required before the FDA will approve an application, and these requirements also apply to marketed products. Companies are also subject to other post-market and general requirements, including compliance with restrictions imposed on marketed products, compliance with promotional standards, record keeping and reporting of certain adverse reactions or events. The FDA regularly inspects companies to determine compliance with the Quality System Regulations and other post-approval requirements. Failure to comply with statutory requirements and the FDA’s regulations can lead to substantial penalties, including monetary penalties, injunctions, product recalls, seizure of products, and criminal prosecution.

The Clinical Laboratory Improvement Act of 1988 (“CLIA”) prohibits laboratories from performing in vitro tests for the purpose of providing information for the diagnosis, prevention or treatment of any disease or impairment of, or the assessment of, the health of human beings unless there is in effect for such laboratories a certificate issued by the United States Department of Health and Human Services (via the FDA) applicable to the category of examination or procedure performed. Although a certificate is not required for the Company, it considers the applicability of the requirements of CLIA in the design and development of its products. The statutory definition of “laboratory” is very broad, and many of our customers are considered labs. A CLIA waiver will remove certain quality control and other requirements that must be met for certain customers to use the Company’s products and this is in fact critical to the marketability of a product into the point-of-care diagnostics market. The Company has received a CLIA waiver for each of the two rapid HIV tests now marketed by Inverness Medical as Clearview® Complete HIV 1/2 and Clearview® HIV 1/2 STAT PAK®. The CLIA waiver was granted by the FDA for HIV 1/2 STAT-PAK on November 20, 2006 and for the Clearview® Complete HIV 1/2 on October 22, 2007.

In addition, the FDA regulates the export of medical devices that have not been approved for marketing in the United States. The Federal Food, Drug and Cosmetic Act contains general requirements for any medical device that may not be sold in the United States and is intended for export. Specifically, a medical device intended for export is not deemed to be adulterated or misbranded if the product: (1) complies with the specifications of the foreign purchaser; (2) is not in conflict with the laws of the country to which it is intended for export; (3) is prominently labeled on the outside of the shipping package that it is intended for export; and (4) is not sold or offered for sale in the United States. Some medical devices face additional statutory requirements before they can be exported. If an unapproved device does not comply with an applicable performance standard or PMA requirement, is exempt from either such requirement because it is an investigational device, or is a banned device, the device may be deemed to be adulterated or misbranded unless the FDA has determined that exportation of the device is not contrary to the public health and safety and has the approval of the country to which it is intended for export. However, the Federal Food, Drug and Cosmetic Act does permit the export of devices to any country in the world, if the device complies with the laws of the importing country and has valid marketing authorization in one of several “listed” countries under the theory that these listed countries have sophisticated mechanisms for the review of medical devices for safety and effectiveness.

The Company is also subject to regulations in foreign countries governing products, human clinical trials and marketing, and may need to obtain approval or evaluations by international public health agencies, such as the World Health Organization, in order to sell diagnostic products in certain countries. Approval processes vary from country to country, and the length of time required for approval or to obtain other clearances may in some cases be longer than that required for United States governmental approvals. On the other hand, the fact that our HIV diagnostic tests are of value in the AIDS epidemic may lead to some government process being expedited. The extent of potentially adverse governmental regulation affecting Chembio that might arise from future legislative or administrative action cannot be predicted.

One or more of the Company’s rapid HIV tests are also approved or pending approval for marketing in several foreign jurisdictions, including but not limited to Brazil, Mexico, and India, as well as a number of other nations in the developing world.

Environmental Laws

To date, we have not encountered any costs relating to compliance with any environmental laws.

Intellectual Property

Intellectual Property Strategy

Our intellectual property strategy is to: (1) build our owned intellectual property portfolio around our Dual Path Platform technology; (2) pursue licenses, trade secrets and know-how within the area of lateral flow technology and DPP®; and (3) develop and acquire proprietary positions to reagents and new hardware platforms for the development and manufacture of rapid diagnostic tests.

Trade Secrets and Know-How

We believe that we have developed a substantial body of trade secrets and know-how relating to the development of lateral flow and DPP® based diagnostic tests, including but not limited to the sourcing and optimization of materials for such tests, and how to maximize sensitivity, speed-to-result, specificity, stability and reproducibility. The Company possesses proprietary know-how to develop tests for multiple conditions using colored latex. Our buffer formulations enable extremely long shelf lives of our rapid HIV tests and we believe that this provides us with an important competitive advantage.

Lateral Flow Technology and Reagent Licenses

As part of our agreements in 2006 with Inverness for the marketing of our HIV tests, we were granted non-exclusive licenses to their lateral flow technology for certain products manufactured and marketed by Chembio including but not limited to our HIV tests. Although we believe our DPP® is outside of the scope of lateral flow patents, we consult with patent counsel, and seek licenses and/or redesigns of products that we believe to be in the best interests of the Company and our stockholders. Because of the costs and other negative consequences of time-consuming patent litigation, we often attempt to obtain a license on reasonable terms. Nevertheless there is no assurance that Inverness’ lateral flow patents will not be challenged or that other patents containing claims relevant to the Company’s products will be not be granted and that licenses to such patents, if any, will be available on reasonable terms, if any. Inverness has aggressively enforced its lateral flow intellectual property, and in 2008 brought a patent infringement lawsuit against Orasure. Orasure has claimed that their Oraquick product does not infringe the Inverness patent and that the Inverness patent is invalid. The lawsuit is in the discovery phase.

In the event that it is determined that a license to any patent is required and it is not possible to negotiate a license agreement under a necessary patent, we may be able to modify the applicable product such that a license would not be necessary. However, this alternative could delay or limit our ability to sell these products in the United States and/or other markets, and/or increase penalties, all of which would adversely affect our results of operations, cash flows and business.

The DPP® technology provides us with our own intellectual property and we believe it also enables tests to be developed with improved sensitivity as compared with comparable tests on lateral flow platforms. The Company has signed and anticipates signing new development projects based upon the DPP® technology that will provide new manufacturing and marketing opportunities. We have several other patents issued or pending related to other point-of-care technologies or applications thereof. The DPP® patent protection is being prosecuted in many foreign jurisdictions as well.

The peptides used in our rapid HIV tests are patented by Adaltis Inc. and are licensed to us under a 10-year non-exclusive license agreement dated August 30, 2002, which was recently amended to reduce the royalty rate. We also have licensed the antigens used in other tests including our Chagas, Tuberculosis and Leishmaniasis tests. In prior years we concluded license agreements related to intellectual property rights owned by the United States associated with HIV- 1, and during the first quarter of 2008 we entered into a sub-license agreement for HIV-2 with Bio-Rad Laboratories N.A., the exclusive licensee of the Pasteur Institute’s HIV-2 intellectual property estate.

Corporate History

On May 5, 2004, we completed a merger with Chembio Diagnostic Systems Inc. through which Chembio Diagnostics Systems Inc. became our wholly-owned subsidiary, and through which the management and business of Chembio Diagnostic Systems Inc. became our management and business. As part of this transaction, we changed our name to Chembio Diagnostics, Inc. In 2003, we had sold our prior business, and as a result, we had no specific business immediately prior to the merger.

Since the formation of Chembio Diagnostic Systems Inc. in 1985, it has been involved in developing, manufacturing, selling and distributing in-vitro diagnostic tests, including rapid tests beginning in 1995, for a number of conditions in humans and animals.

On March 12, 2004, we implemented a 1-for-17 reverse split of our common stock. All references in this Form 10-K to shares of our common stock have been adjusted to reflect this reverse split.

Glossary

AIDS	Acquired Immunodeficiency Syndrome. AIDS is caused by the Human Immunodeficiency Virus, HIV.
ALGORITHM (parallel or serial)	For rapid HIV testing this refers both to method or protocol (in developing countries to date) for using rapid tests from different manufacturers in combination to screen and confirm patients at the point-of-care, and may also refer to the specific tests that have been selected by an agency or ministry of health to be used in this way. A parallel algorithm uses two screening tests from different manufacturers and a tie-breaker test only if there is a discrepancy between the screening tests results. A serial algorithm only uses a second confirmatory test if there is a positive result from the screening test, meaning that the number of confirmatory tests used is equal to the positivity rate in the testing venue. A tie-breaker test resolves discrepancies between the screen and the confirmatory test.
ANTIBODY	A protein which is a natural part of the human immune system produced by specialized cells to neutralize antigens, including viruses and bacteria that invade the body. Each antibody producing cell manufactures a unique antibody that is directed against, binds to and eliminates one, and only one, specific type of antigen.
ANTIGEN	Any substance which, upon entering the body, stimulates the immune system leading to the formation of antibodies. Among the more common antigens are bacteria, pollens, toxins, and viruses.
ARVs	Anti-Retroviral Treatments for AIDS
CD-4	The CD4+ T-lymphocyte is the primary target for HIV infection because of the affinity of the virus for the CD4 surface marker. Measures of CD4+ T-lymphocytes are used to guide clinical and therapeutic management of HIV-infected persons.
CDC	United States Centers for Disease Control and Prevention
CLIA waiver	Clinical Laboratory Improvement Act designation that allows simple tests to be performed in point-of-care settings such as doctors offices, walk-in clinics and emergency rooms.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

This discussion and analysis should be read in conjunction with the accompanying Consolidated Financial Statements and related notes. Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of any contingent liabilities at the financial statement date and reported amounts of revenue and expenses during the reporting period. On an ongoing basis we review our estimates and assumptions. Our estimates were based on our historical experience and other assumptions that we believe to be reasonable under the circumstances. Actual results are likely to differ from those estimates under different assumptions or conditions, but we do not believe such differences will materially affect our financial position or results of operations. Our critical accounting policies, the policies we believe are most important to the presentation of our financial statements and require the most difficult, subjective and complex judgments, are outlined below in ‘‘Critical Accounting Policies,’’ and have not changed significantly.

In addition, certain statements made in this report may constitute “forward-looking statements”. These forward-looking statements involve known or unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Specifically, 1) our ability to obtain necessary regulatory approvals for our products; and 2) our ability to increase revenues and operating income, is dependent upon our ability to develop and sell our products, general economic conditions, and other factors. You can identify forward-looking statements by terminology such as “may,” “could”, “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continues” or the negative of these terms or other comparable terminology. Although we believe that the expectations reflected-in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements.

The following management discussion and analysis relates to the business of the Company, including its subsidiaries, which develop, manufacture, and market rapid diagnostic tests that detect infectious diseases. The Company’s main products presently commercially available are three rapid tests for the detection of HIV antibodies in whole blood, serum and plasma samples, all of which employ lateral flow technology and two of which were approved by the FDA in 2006. In addition, we have a fourth rapid HIV test, more recently developed on our patented Dual Path Platform (DPP®) technology, for the detection of antibodies to HIV in oral fluid samples, as well as in whole blood, serum and plasma samples. The products which employ lateral flow technology are manufactured and sold under a non-exclusive license we have from Inverness Medical Innovations, Inc. (“Inverness”), which is also our exclusive marketing partner for the FDA-approved products in the United States (as well as Europe and Asia for the product that is known as the “barrel” format product) under its Clearview® brand. Inverness launched its marketing of these products in the United States in February 2007. Chembio’s two HIV STAT-PAK® rapid HIV tests (in cassette and dipstick formats) are marketed outside the United States through different partners and channels under our license from Inverness.

Rapid HIV tests represented nearly 90% of the Company’s product revenues in 2008. The Company also has other rapid tests that together represented approximately 10% of sales in 2008. The Company’s products are sold to medical laboratories and hospitals, governmental and public health entities, non-governmental organizations, medical professionals and retail establishments. Chembio’s products are sold under the Company’s STAT PAK® or SURE CHECK ® registered trademarks or under the private labels of its marketing partners, for example the Clearview® label owned by Inverness Medical Innovations, Inc.

All of the Company’s future products that are currently being developed are based on its patented Dual Path Platform (DPP®), which is a unique diagnostic point-of-care platform that has certain advantages over lateral flow technology. In 2008 the Company completed development of its first two products that employ the DPP® technology and it has a number of additional products under development that employ the DPP® technology. These product development activities are further explained below.

Oswaldo Cruz Foundation Agreements

During 2008 we signed four agreements with the Oswaldo Cruz Foundation (FIOCRUZ) in Brazil relating to products for Leptospirosis, Leishmaniasis, screening for HIV 1/2 with oral fluid samples, and confirmation of HIV 1. We have completed development of two of the products (Leishmaniasis and HIV oral fluid screening test), and substantially completed development of the other two. All four of these products are or will be undergoing regulatory approval evaluations in Brazil; we expect that all of these products will be approved by ANVISA for distribution by FIOCRUZ in Brazil during 2009, triggering initial orders as well as approximately $1MM in technology transfer fee payments to the Company in 2009. We received purchase orders from FIOCRUZ in the fourth quarter of 2008 for approximately $500,000 of the Leishmaniasis product; however due to the delay in FIOCRUZ receiving necessary import authorizations for the second and larger portion of this order, approximately $380,000 of this amount could not be shipped in December and was instead shipped during the first quarter of 2009. Also, based upon additional features that we are adding to the HIV confirmatory test, we are finalizing a revised agreement for this product which we believe will provide us with a larger market opportunity for this product in Brazil subject to regulatory approval and other conditions.

On April 16, 2008, we announced a new development agreement with Bio-Rad Laboratories N.A.., a part of Bio-Rad Laboratories Inc, a leading in-vitro diagnostic and life science company. The agreement with Bio-Rad is for the development of a new multiplex product that is being developed on DPP® and which would be marketed by Bio-Rad under a limited exclusive license from Chembio to Bio-Rad that is limited to this field of application. Our agreement with Bio-Rad contemplated that we would enter into a license agreement effective no later than December 2008 subject to Bio-Rad being satisfied with development progress and other conditions. We in fact did enter into this license agreement in January 2009 with a December 31, 2008 effective date and have received a $340,000 payment for this license. Development of this product is anticipated to continue through 2009, funded by Bio-Rad at a cost of $125,000 every six months. The agreement is terminable at any time by Bio Rad and, under certain circumstances, some or all of the $340,000 license fee is refundable.

DPP® HIV Oral Fluid Test Status

Having completed development of this product in 2008 for international sales, we are now in the initial stages of commercializing it to participate in the US and global markets. We are initially pursuing approval and registration of this product in the large markets globally including but not limited to those markets where we have been successful with our current lateral flow tests that only use finger-stick whole blood and other blood matrices (venous whole blood, serum and plasma). Our product is being included in a study in Africa that is being conducted by a governmental organization interested in the possibility of expanded use of oral fluid based tests. We are also negotiating an agreement with a large global in-vitro diagnostic products company that would have exclusive marketing rights to this product in the United States market under a co-branding of the product that would include the DPP® trademark in the name of the product. (See RECENT DEVELOPMENTS AND CHEMBIO’S PLAN OF OPERATIONS FOR THE NEXT TWELVE MONTHS).

Progress on DPP® Syphilis Screen and Confirm Multiplex Test

During 2008 and 2009 year to date, we made substantial progress on this product, with extensive collaborative efforts with the CDC and others. We are currently evaluating whether this product meets the performance objectives for the US market while we continue to assess and focus on the market opportunity for this product in the United States.

Other DPP® Development Projects

Our patented DPP® technology, combined with our development and manufacturing experience and know-how, has enabled us to attract and enter into and pursue third-party-funded product development opportunities that in turn add further to our capabilities while subsidizing some of our R&D personnel and overall overhead costs. This allows us to maintain a larger R&D staff than we could otherwise justify, which also gives us some flexibility in how and when we allocate resources. Included in our research and development organization is a technical team that we created in 2008. This team is able to transfer products from R&D into production and assist in validation, is involved in supporting our manufacturing organization when the need arises, and is also able to assist in pure development activities. Creation of this team was an important accomplishment in 2008.

Chembio continues to work with commercial, governmental and private organizations in order to obtain research grants and other funding for development projects. In this regard, we have entered into a development agreement with Bio-Rad, which, subject to continued achievement of milestones and other conditions, could result in approximately $200,000 of development funds for Chembio in 2009. We also have DPPÒ grants from governmental agencies for $55,000 for leprosy research and $110,000 for Human TB Serology research in 2009. Our four technology transfer, supply and license agreements with Oswaldo Cruz Foundation of Brazil could result in as much as $1,050,000 of advance royalty payments. In addition to the projects described, Chembio has applied for other research grants and is working on entering into a number of other development agreements.

There can be no assurance that any of these projects will continue, meet regulatory or other technical requirements and specifications, and/or that if continued, will result in completed products, or that such products, if successfully completed, will be successfully commercialized.

Regulatory Activities

We are pursuing registrations of our lateral flow and DPP® HIV products in a number of other jurisdictions, and also pursing registrations with the USDA of additional claims for our veterinary tuberculosis products.

Recent Events

During the quarter ended December 31, 2008, Inverness Medical Innovations, Inc. (“Inverness”) notified the Company that Inverness had entered into a contract with Bio-Rad Laboratories, Inc. (“Bio-Rad”) for royalties on Bio-Rad’s patent for the detection of HIV-2 antibodies. The agreement also provided for Inverness to pay past royalties. The agreements between the Company and Inverness provide that the Company is to share in these past royalties and Inverness requested it be reimbursed for the Company’s share of these past royalties. The Company and Inverness have agreed that this liability, which is approximately $500,000, is to be paid from future revenues over approximately the next 18 months.

For the year ended December 31, 2008 the Company reclassified its royalty and license expenses to cost of goods sold, instead of selling, general and administrative expenses.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 2008 AS COMPARED WITH THE YEAR ENDED DECEMBER 31, 2007

Revenues:

Selected Product Categories:	For the years ended
	December 31, 2008		December 31, 2007		$ Change		% Change

HIV	$	9,192,297	$	7,927,676	$	1,264,621		15.95	%
TB		281,555		111,403		170,152		152.74	%
Other		881,916		725,798		156,118		21.51	%
Net Product Sales		10,355,768		8,764,877		1,590,891		18.15	%

Research grant income		693,803		466,071		227,732		48.86	%
Total Revenues	$	11,049,571	$	9,230,948	$	1,818,623		19.70	%

Revenues for our HIV tests and related components during the year ended December 31, 2008 increased by $1.26 million over the same period in 2007. This was primarily attributable to increased sales in Brazil and sales to our distributor in the United States, offset by the reduction of sales to Mexico from 2007 that were not repeated in 2008. Sales of our TB product increased because of additional products being approved. The increase in research grant income was for grants and feasibility studies involving our patented DPP® technology of which $651,000 was received and $694,000 was earned in 2008, utilizing $43,000 in deferred revenues as of December 31, 2007. Sales to Africa (see Note 13 of the financial statements) were primarily from Nigeria of approximately $2.86 million. We have been advised recently that our designation in Nigeria as one of the screening tests has changed to that of the confirmatory test as this country moves from a parallel to a serial testing algorithm, which we expect will significantly reduce our sales to Nigeria in 2009.

Gross Margin:

Gross Margin related to	For the years ended
Net Product Sales:	December 31, 2008			December 31, 2007			$ Change		% Change

Gross Margin per Statement of Operations	$	3,851,721		$	2,795,710		$	1,056,011		37.77	%

Gross Margin %		30.49	%		26.58	%

The increase in our gross margin resulted primarily from increased quantities of our product sales and increased average unit prices on product sales and component sales.

For the year ended December 31, 2008, the Company reclassified its royalty and license expenses to cost of goods sold. For all periods prior to the quarter ended December 31, 2008 these expenses were previously reflected in selling, general and administrative expenses. Without this reclassification of royalty and license expenses from SG&A expense to Cost of Goods Sold, the gross margin from product sales would have been $4.465 million, or 43.1%, and $3.396 million, or 38.7%, for the years ended December 31, 2008 and 2007, respectively.

Research and Development:

This category includes costs incurred for product research and development, regulatory approvals, technical support, evaluations and registrations.

Total Research and Development	$	2,605,343	$	1,906,653		$	698,690			36.64	%

Expenses for Clinical & Regulatory Affairs for the year ended December 31, 2008 increased by $219,500 as compared to the same period in 2007. This was primarily due to an increase in expenses related to internal DPP testing, external clinical trials we contracted for in order to lower the age limitation of our FDA approved rapid HIV tests from 18 to 13 years of age, and also due to an increase in wages and related costs as we added to our regulatory staff, offset by a decrease in the use of consultants

Expenses other than Clinical & Regulatory Affairs increased by $479,200 in the year ended December 31, 2008 as compared with the same period in 2007 and were primarily related to an increase in personnel and material costs required to perform the work related to funded feasibility studies and grants received, all related to our patented DPP® technology, and to the establishment of a technical group within the R&D department in order to support product validations and transfers to production. These increases were partially offset by a decrease in the cost of share-based compensation related to the value of common stock and employee stock options issued to an employee pursuant to a contract.

Subject to the continuation of grant and feasibility income, the Company currently plans to continue research and development spending at levels that will, net of grant and feasibility study income, result in a net decrease in this spending category.

Total S, G &A	$	3,317,046	$	3,765,221	$	(448,175	)		-11.90	%

Selling, general and administrative expenses for the year ended December 31, 2008 decreased by 12% as compared with the same period in 2007. Reduced personnel expenses, investor relations expenses, and professional fees were partially offset by increases in sales commissions that resulted from commissionable sales in Brazil that increased significantly in 2008 as compared with 2007. The decreased cost of professional fees (legal, accounting and section 404 of Sarbanes-Oxley) were related to the reduction of legal fees related to the Plan (see Recent Events above), which were almost all incurred in 2007. These decreased costs were partially offset by increased fees to our independent auditors.

Other Income and Expense:

Total Other Income and Expense	$	121,898		$	249,272		$	(127,374	)		-51.10	%

Other income for the year ended December 31, 2008 decreased 21% as compared with the same period in 2007 primarily as a result of a decrease in the net amounts received from New York State related to a program for qualified emerging technology companies. Interest income for the year ended December 31, 2008 decreased due to a decrease in available funds to invest in interest bearing accounts. Decreased interest expense in 2008 as compared with 2007 reflects the impact of lower interest payments for capital leases nearing the end of their terms

The Company had a decrease in cash for the year ended December 31, 2008 as compared to a lesser decrease in cash for the same period in 2007. The decrease during the 2008 and 2007 periods is primarily attributable to the cash used in operations.

The Company had a working capital surplus of $1,664,000 at December 31, 2008 and a working capital surplus of $3,229,000 at December 31, 2007. The Company estimates that its resources are sufficient to fund its needs through the end of 2009 and beyond or that, in the alternative, it could raise additional capital although the terms under which that capital could be raised would likely be very dilutive to current shareholders. The Company’s liquidity and cash requirements will depend on several factors. These factors include (1) the level of revenues (the Company received $340,000 in 2009 for license fees for which we need to meet certain milestones to earn); (2) the extent to which, if any, that revenue level improves operating cash flows; (3) the Company’s investments in research and development, facilities, marketing, regulatory approvals, and other investments it may determine to make; and (4) the investment in capital equipment (including production equipment of $323,500 that the Company has contracted for) and the extent to which it improves cash flow through operating efficiencies. There are no assurances that the Company will become profitable or generate positive cash flow by the end of 2009 or, in the alternative, be successful in raising sufficient capital to fund its needs through 2009.

RECENT DEVELOPMENTS AND CHEMBIO’S PLAN OF OPERATIONS FOR THE NEXT TWELVE MONTHS

Please see section entitled Recent Events above.

2008

During 2008 Chembio increased total revenues by 20% to $11.05MM, increased gross profit by 38% to $3.85MM (based on the presentation in Item 6 Selected Financial Data wherein our reclassification of Royalty Expense and License Fees, reclassified to Cost of Goods Sold in our audited statements for 2008, were also reclassified, for 2004-2007 for comparative purposes), and decreased Selling, General & Administrative Expense by 12% to $3.32MM. Research and Development Expense, net of Research Grant Income, increased 33% to $1.91MM.

2008 revenue growth was attributable to our continued collaboration in Brazil with Oswaldo Cruz Foundation and to strong sales growth to Africa, including but not limited to Nigeria, to and through major programs led by the Global Fund and PEPFAR. Even though our sales to Inverness were less in 2008 than in 2007, this was primarily a result of purchases made by Inverness at the time of the launch in 2007 in excess of the actual demand from their customers in 2007, which in turn was in part a result of delays in our obtaining both the age claim amendment and the CLIA waiver for the barrel product (See Item 1. Business: Regulatory Activities). We believe Inverness’ sales of our products increased significantly in 2008 versus 2007, notwithstanding a voluntary component (control kit) recall that occurred during the first half of 2008. With continued sales increases by Inverness to its customers in 2009, which we believe is likely, we would expect to see commensurate increases in our sales to Inverness, as we believe that Inverness’ inventories have been substantially reduced as compared to 2008.

Our improved gross margin percentage, even after the fourth quarter 2008 royalty expenses related to prior quarters, occurred as a result of continued cost and efficiency improvements as well as improved product mix, primarily as a result of lower unit production costs for components sold to Brazil. Decreased SG&A costs were achieved through termination of positions within these departments and reduction in other costs throughout this cost area. Our net increase in Research & Development expenses included our costs of completing the lowering of the age limit of our FDA approved rapid HIV tests, as well as the cost of establishing a technical department within R&D that can alternatively support operations, transfer new products to operations, research process improvements, and to the extent there is available capacity within this group, support traditional R&D activities.

2009

Based upon (1) the growing base of business we have in the United States for our two FDA-approved CLIA-waived rapid HIV tests, resulting both from the expansion of the market and from market share gains by our marketing partner Inverness Medical; (2) continued growth opportunities for our rapid HIV test products globally, and; (3) our expectation that 2009 will bring our first significant revenues from our DPP® technology, primarily as a result of the contracts we signed with the Oswaldo Cruz Foundation in 2008, we believe we are positioned for increases in our revenues and improvement in our overall operating results in 2009.

Our base plan for 2009 assumes the following: (1) Growth in our sales to Inverness, as it makes gains in hospital and public health markets and because inventory levels that it brought into 2008 have been normalized, (2) conservative assumptions with regard to our international HIV business, primarily including a significant reduction from Nigeria, partially offset by expected growth from our HIV business through new distribution opportunities in Asia, Africa, South America and, upon receipt of our CE Mark, Europe, and (3) successful execution for approval and sales of our DPP® products pursuant to the contracts we signed with Oswaldo Cruz Foundation in 2008.

We intend to continue improving our manufacturing efficiencies and controlling our SG&A expenses, resulting in continued anticipated improvements in our operating results. Even though we made significant cost reductions during 2008, given the reduced sales from Nigeria, an extremely uncertain economy, and the most challenging financing environment for debt or equity of our time, during the first quarter of 2009 we made additional cost reductions in all departments of the Company, including elimination of a number of salaried positions and implementation of a company-wide pay reduction program for all salaried employees earning at least $30,000, with appropriately larger reductions for those earning higher amounts. During 2008 and 2009 year-to-date we have also eliminated salaries in our sales and marketing and administrative areas, which represented annualized costs in excess of $500,000, exclusive of benefits and other attendant costs. Though this limits some new business development opportunities, many of our new sales opportunities are being developed either through OEM customer relationships, exclusive distribution arrangements, and/or commissioned agents, all of which have enabled us to reduce our sales and marketing costs significantly.

Research & Development expenses in 2009 are budgeted as flat overall when compared with 2008. However, based upon current and pending research and development income from grants, development contracts and feasibility studies (and associated staffing requirements for such commitments), our net R&D cost in 2009 (R&D income less total R&D expense) should decrease substantially as well. Having these external funds for R&D is helping us to increase our experience and capabilities while limiting our cash investment. Should pending contracts not materialize, we will make commensurate adjustments to our Research & Development expenses.

In addition to the DPP® products we anticipate launching in Brazil through Oswaldo Cruz Foundation this year, our contract development work for Bio-Rad Laboratories, and several other research and development programs, our main DPP® products that we are focusing our R&D activities on are our DPP® HIV 1/2 screening test for use with oral fluids and our DPP® Syphilis Screen and Confirm test We are in discussions with a large in vitro diagnostics marketing organization that, if an actual agreement is completed, would fund all external regulatory costs, co-brand this product with our DPP® trademark, and commit to minimum sales of the product in exchange for our granting to it exclusive U.S. marketing rights to this product. We are also actively pursuing opportunities for our oral fluid HIV test in the international markets that we already participate in, as well as others, and we are very encouraged by the interest we have received in this product offering.

Equipment Purchase Commitment:

In January of 2009, the Company entered into an agreement with an equipment manufacturer to design and build equipment that will be used to automate the assembling of our tests and lower our production costs. The estimated cost of $323,500 is being paid in installments.

Critical Accounting Policies and Estimates

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates.

We believe that there are several accounting policies that are critical to understanding our historical and future performance, as these policies affect the reported amounts of revenue and the more significant areas involving management’s judgments and estimates. These significant accounting policies relate to revenue recognition, research and development costs, valuation of inventory, valuation of long-lived assets and income taxes. These policies, and the related procedures, are described in detail below.

Revenue Recognition –

We sell our products directly through our sales force and through distributors. Revenue from direct sales of our product are recognized upon shipment to the customer. Income from research grants are recognized in earnings in the period in which the related expenditures are incurred. Sales are recorded net of discounts, rebates and returns.

Research & Development Costs –

Research and development activities consist primarily of new product development, continuing engineering for existing products, regulatory and clinical trial costs. Costs related to research and development efforts on existing or potential products are expensed as incurred.

Valuation of Inventories –

Inventories are stated at the lower of cost or market, using the first-in, first-out method (FIFO) to determine cost. Our policy is to periodically evaluate the market value of the inventory and the stage of product life cycle, and record a reserve for any inventory considered slow moving or obsolete. For example, each additional 1% of obsolete inventory would reduce such inventory by approximately $18,000.

Allowance for doubtful accounts –

Our policy is to review our accounts receivable on a periodic basis, no less than monthly. On a quarterly basis an analysis is made of the adequacy of our allowance for doubtful accounts and adjustments are made accordingly. The current allowance is approximately .83% of accounts receivable. For example each additional 1% of accounts receivable that becomes uncollectible would reduce such balance of accounts receivable by approximately $12,000.

Income Taxes –

Income taxes are accounted for under FAS No. 109, “Accounting for Income Taxes.” FAS No. 109 requires the asset and liability method of accounting for deferred income taxes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities. Deferred tax assets or liabilities at the end of each period are determined using the tax rate expected to be in effect when taxes are actually paid or recovered. For example, if we do not become profitable, we may be unable to utilize our deferred tax asset, which approximates $8,598,000 at December 31, 2008.

FAS 109 also requires that a valuation allowance be established when it is more likely than not that all or a portion of a deferred tax asset will not be realized. A review of all available positive and negative evidence needs to be considered, including a company’s current and past performance, the market environment in which the company operates, length of carryback and carryforward periods and existing contracts that will result in future profits.

Forming a conclusion that a valuation allowance is not needed is difficult when there is negative objective evidence such as cumulative losses in recent years. Cumulative losses weigh heavily in the overall assessment. As a result, we determined that it was appropriate to establish a valuation allowance for the full amount of our deferred tax assets.

The Company adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”) on January 1, 2007. FIN 48 prescribes a comprehensive model for recognizing, measuring, presenting and disclosing in the consolidated financial statements tax positions taken or expected to be taken on a tax return, including a decision whether to file or not to file in a particular jurisdiction.

The calculation of our tax liabilities involves the inherent uncertainty associated with the application of complex tax laws. We are subject to examination by various taxing authorities. We believe that as a result of our losses sustained to date, any examination would result in a reduction of our net operating losses rather than a tax liability. As such, we have not provided for additional taxes estimated under FIN 48, Accounting for Uncertainty in Income Taxes.

The above listing is not intended to be a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by accounting principles, generally accepted in the United States of America, with no need for management’s judgment in their application. There are also areas in which management’s judgment in selecting any viable alternative would not produce a materially different result. See our audited financial statements and notes thereto which contain accounting policies and other disclosures required by accounting principles generally accepted in the United States of America.

DESCRIPTION OF PROPERTY

Our administrative offices and research facilities are located in Medford, New York. We lease approximately 18,200 square feet of industrial space for $11,987 per month. The space is utilized for research and development activities (approximately 2,660 square feet), offices (approximately 1,820 square feet) and production (approximately 13,720 square feet). The lease term expires on April 30, 2009, and the Company has an option to renew for an additional two years. Additional space may be required as we expand our research and development activities. We do not foresee any significant difficulties in obtaining any required additional facilities.

As of the filing date of this Prospectus, the Company is in discussion for a lease extension for its administrative offices and research facilities. The principal terms being discussed are as follows: (a) a lease term of five years; (b) an initial rent of $11,350 per month; (c) the monthly rent for year two of the lease will increase by the lower of (i) the change in the consumer price index, or (ii) five percent; and (d) the monthly rent for years three through five of the lease will increase each year by the lower of (i) the change in the consumer price index, or (ii) two and one half percent. Although the Company believes that the extension will be entered into on terms that are substantially similar to the terms being discussed, there is no assurance that this will occur.

LEGAL MATTERS

The validity of the shares of our common stock offered by the Selling Stockholders has been passed upon by the law firm of Patton Boggs, LLP.

MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

Market Information

Our common stock is quoted on the OTC Bulletin Board under the symbol “CEMI.” The table below sets forth the high and low bid prices per share of our common stock for each quarter of our two most recently completed fiscal years. These prices represent inter-dealer quotations without retail markup, markdown, or commission and may not necessarily represent actual transactions.

Fiscal Year 2008	High Bid	Low Bid
First Quarter	$0.30	$0.11
Second Quarter	$0.26	$0.08
Third Quarter	$0.28	$0.15
Fourth Quarter	$0.21	$0.10

Fiscal Year 2007	High Bid	Low Bid

Third Quarter	$0.65	$0.37
Fourth Quarter	$0.57	$0.26

Rule 15g-9 of the Securities and Exchange Commission, known as the Penny Stock Rule, imposes requirements on broker/dealers who sell securities subject to the rule to persons other than established customers and accredited investors. For transactions covered by the rule, brokers/dealers must make a special suitability determination for purchasers of the securities and receive the purchaser’s written agreement to the transaction prior to sale. The Securities and Exchange Commission also has rules that regulate broker/dealer practices in connection with transactions in “penny stocks.” Penny stocks generally are equity securities with a price of less than $5.00 (other than securities registered on certain national securities exchanges or quoted on the NASDAQ system, provided that current price and volume information with respect to transactions in that security is provided by the exchange or system), except for securities of companies that have tangible net assets in excess of $2,000,000 or average revenue of at least $6,000,000 for the previous three years. The Penny Stock Rule requires a broker/ dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document prepared by the Commission that provides information about penny stocks and the nature and level of risks in the penny stock market. The broker/dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker/dealer and its salesperson in the transaction, and monthly account statements showing the market value of each penny stock held in the customer’s account. The bid and offer quotations, and the broker/dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the customer in writing before or with the customer’s confirmation. These disclosure requirements have the effect of reducing the level of trading activity in the secondary market for penny stock issues. As a result of these rules, investors sometimes find it difficult to sell shares of penny stock issuers. At the present time, transactions in our common stock are not subject to the Penny Stock Rule because our average revenue for 2006, 2007 and 2008 exceeded $6 million per year. However, there can be no assurance that transactions in our common stock will not be subject to the Penny Stock Rule in the future.

Holders

As of January 15, 2009, there were approximately 875 record owners of our common stock.

Dividends

The Company has never paid cash dividends on its common stock and has no plans to do so in the foreseeable future.

2 All options issued with a $.75 exercise price and an April 17, 2006 vesting date were issued on April 17, 2006 as part of the Company’s 1999 Stock Option Plan. Pursuant to this plan, the Company granted 244,000 options to all employees. On April 17, 2006, the Company’s Compensation Committee approved the cancellation of each employee stock option award issued under the 1999 Stock Option Plan where the exercise price was greater than $0.75 per share of the Company’s common stock, and the issuance of a new stock option award under the 1999 Stock Option Plan, for the same number of shares of the Company’s common stock, with an exercise price of $0.75 per share of the Company’s common stock for each cancelled stock option award. The market price of the common stock of the Company on April 17, 2006 was $0.72 per share. In total, stock option awards to acquire 795,000 shares of Company common stock were cancelled, and stock option awards to acquire 795,000 shares of Company common stock were issued. Other than the change in the exercise price, all of the terms and conditions in each newly issued stock option award are identical to the cancelled stock option award it replaced, with the following exceptions: (i) Lawrence A. Siebert’s stock option award for 50,000 shares of the Company’s common stock, exercisable on May 28, 2006 and terminating on May 28, 2011, was replaced with a stock option award for 50,000 shares of the Company’s common stock, exercisable on January 1, 2007 and terminating on May 28, 2011;(ii) Avi Pelossof’s stock option awards for 72,500 shares of the Company’s common stock, exercisable on May 28, 2005 and on May 28, 2006 and both terminating on May 28, 2011 was replaced with a stock option award for 72,500 shares of the Company’s common stock, exercisable on January 1, 2007 and terminating on May 28, 2011.

6 Stock issued in connection with an employment contract and under the 2008 Stock Incentive Plan.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS

ON ACCOUNTING AND FINANCIAL DISCLOSURE

As disclosed in the Company's Amendment No. 2 to Form 8-K/A filed with the SEC on March 3, 2009, on February 15, 2009, the practice of Lazar Levine & Felix LLP (“Lazar”), an independent registered public accounting firm, was acquired by Parente Randolph, LLC (“Parente”) in a transaction pursuant to which Lazar merged its operations into Parente and certain of the professional staff and partners of Lazar joined Parente either as employees or principals of Parente. On February 19, 2009, as a result of this transaction, Lazar resigned from its role as principal auditor of the Company’s financial statements. The Company, through and with the approval of the Audit Committee of the Company’s Board of Directors, engaged Parente as its independent registered public accounting firm.

Lazar’s reports regarding the Company’s financial statements for the fiscal years ended December 31, 2007 and 2006 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the years ended December 31, 2008 and 2007, and during the interim period from the end of the most recently completed fiscal year through February 19, 2009, the date of resignation, there were no disagreements with Lazar on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Lazar would have caused it to make reference to such disagreement in its reports.

During the years ended December 31, 2008 and 2007, and during the interim period from the end of the most recently completed fiscal year through February 19, 2009, the date of engagement, the Company did not consult with Parente regarding the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinions that might be rendered by Parente on the Company’s financial statements. Parente did not provide the Company a written report or any oral advice that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue.

In addition, during the years ended December 31, 2008 and 2007, and during the interim period from the end of the most recently completed fiscal year through February 19, 2009, the date of engagement, the Company did not consult with Parente on any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to this item) or a reportable event (as described in Item304(a)(1)(v) of Regulation S-K). As such none of the required disclosures under Item 304(a)(2)(ii) apply.

To The Board of Directors

Chembio Diagnostics, Inc. and Subsidiaries

Medford, New York

We have audited the consolidated balance sheet of Chembio Diagnostics, Inc. and Subsidiaries (the “Company”) as of December 31, 2008 and the consolidated statements of operations, stockholders' equity and cash flows for the year ended December 31, 2008. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Chembio Diagnostics, Inc. and Subsidiaries as of December 31, 2008, and the consolidated results of its operations and its cash flows for the year ended December 31, 2008 in conformity with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2008 AND 2007

NOTE 1 — DESCRIPTION OF BUSINESS:

Chembio Diagnostics, Inc. (the “Company” or “Chembio”) and its subsidiaries develop, manufacture, and market rapid diagnostic tests that detect infectious diseases. The Company’s main products are three rapid tests for the detection of HIV antibodies in whole blood, serum and plasma samples, two of which were approved by the FDA in 2006; the third is sold for export only. Rapid HIV tests represented nearly 90% of the Company’s product revenues in 2008. The Company also has other rapid tests that together represented approximately 10% of sales in 2008. The Company’s products are sold to medical laboratories and hospitals, governmental and public health entities, non-governmental organizations, medical professionals and retail establishments. Chembio’s products are sold under the Company’s STAT PAK® or SURE CHECK ® registered trademarks or under the private labels of its marketing partners, for example the Clearview® label owned by Inverness Medical Innovations, Inc., which is the Company’s exclusive marketing partner for its rapid HIV lateral flow test products in the United States. These products employ lateral flow technologies that are proprietary and/or licensed to the Company. All of the Company’s products that are currently being developed are based on its patented Dual Path Platform (DPP®), which is a unique diagnostic point-of-care platform that has certain advantages over lateral flow technology. In 2008, the Company completed development of its first two products that employ the DPP® and has a number of additional products under development that employ the DPP®.

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which contemplate continuation of the Company as a going concern. Although revenues and gross margins increased in the year ended December 31, 2008 as compared to the same period in 2007, the Company continues to generate significant operating losses. At December 31, 2008, the Company had a positive stockholders’ equity of $2,577,000 and working capital of $1,664,000. The Company estimates that its resources are sufficient to fund its needs through the end of 2009 and beyond or that, in the alternative, it could raise additional capital although the terms under which that capital could be raised would likely be very dilutive to current shareholders. The Company’s liquidity and cash requirements will depend on several factors. These factors include (1) the level of revenues (the Company received $340,000 in 2009 for license fees for which we need to meet certain milestones to earn); (2) the extent to which, if any, that revenue level improves operating cash flows; (3) the Company’s investments in research and development, facilities, marketing, regulatory approvals, and other investments it may determine to make; and (4) the investment in capital equipment (including production equipment of $323,500 that the Company has contracted for) and the extent to which it improves cash flow through operating efficiencies. There are no assurances that the Company will become profitable or generate positive cash flow by the end of 2009 or, in the alternative, be successful in raising sufficient capital to fund its needs through 2009.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES:

(a)	Principles of Consolidation:

The consolidated financial statements include the accounts of the Company, and its wholly owned subsidiary. All intercompany transactions and balances have been eliminated in consolidation.

(b)	Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fair values of cash and cash equivalents, accounts receivable, prepaid expenses and other current assets and accounts payable and accrued expenses reflected in these financial statements approximate carrying value as these are short-term in nature.

(d)	Statements of Cash Flows:

For purposes of the statements of cash flows the Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

(e)	Concentrations of Credit Risk:

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of temporary cash investments and trade receivables. The Company places its temporary cash instruments with well-known financial institutions and, at times, may maintain balances in excess of the $250,000 FDIC Insurance limit. The Company monitors the credit ratings of the financial institutions to mitigate this risk. The Company maintains three accounts with a well established multi-national bank and as of December 31, 2008 had approximately $1.1 million above these limits. Concentration of credit risk with respect to trade receivables is principally mitigated by the Company’s obtaining of letters of credit from certain foreign customers, and its diverse customer base both in number of customers and geographic locations. We currently do not require collateral.

(f)	Inventories:

Inventories, consisting of material, labor and manufacturing overhead, are stated at the lower of cost or market. Cost is determined on the first-in, first-out method.

(g)	Fixed Assets:

Fixed assets are stated at cost less accumulated depreciation. Depreciation is computed using the straight line method over the estimated useful lives of the respective assets, which range from three to seven years. Leasehold improvements are amortized over the useful life of the asset or the lease term, whichever is shorter.

(h)	License Agreement:

In February 2008, the Company entered into a sublicense agreement (see Note 6) for which it has recorded an asset of $1,000,000. This asset is being expensed over an estimated economic life of ten years. The current portion of this asset is $100,000 and is reported in prepaid expenses and other current assets. The long-term portion as of December 31, 2008 is $800,000 and is reflected in other assets along with other unexpensed long-term license fees of $140,000.

(i)	Impairment of Long-Lived Assets and Intangible Assets

In accordance with FAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", long-lived assets to be held and used are analyzed for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. The Company evaluates at each balance sheet date whether events and circumstances have occurred that indicate possible impairment. If there are indications of impairment, the Company uses future undiscounted cash flows of the related asset or asset grouping over the remaining life in measuring whether the assets are recoverable. In the event such cash flows are not expected to be sufficient to recover the recorded asset values, the assets are written down to their estimated fair value. We believe that the carrying values of our long-lived tangible and intangible assets were realizable at December 31, 2008.

(j)	Revenue Recognition:

The Company recognizes revenue in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB 104”). Under SAB 104, revenue is recognized when there is persuasive evidence of an arrangement, delivery has occurred or services have been rendered, the sales price is determinable, and collectability is reasonably assured. Revenue typically is recognized at time of shipment. Sales are recorded net of discounts, rebates and returns.

The Company recognizes income from research projects and grants when earned. Grants are invoiced after expenses are incurred. Any projects or grants funded in advance are deferred until earned.

(k)	Shipping and Handling Costs:

We incur shipping and handling costs associated with the shipment of goods to customer and independent distributors. All shipping and handling amounts billed to customers are included in net sales. All shipping and handling costs associated with the shipment of goods to customers are netted against the amounts billed and are reflected in net sales. All other shipping and handling costs are included in selling, general and administrative expenses.

(l)	Research and Development:

Research and development costs are charged to expense as incurred.

(m)	Stock Based Compensation:

The Company’s 2008 Stock Incentive Plan and 1999 Stock Option Plan (“Plans”) are accounted for in accordance with the recognition and measurement provisions of Statement of Financial Accounting Standards ("FAS") No. 123 (revised 2004), Share-Based Payment ("FAS 123(R)"). FAS 123(R) requires compensation costs related to share-based payment transactions, including employee stock options, to be recognized in the financial statements. In addition, the Company adheres to the guidance set forth within Securities and Exchange Commission ("SEC") Staff Accounting Bulletin No. 107 ("SAB 107"), which provides the Staff's views regarding the interaction between FAS No. 123(R) and certain SEC rules and regulations and provides interpretations with respect to the valuation of share-based payments for public companies. See Note 12 for further details.

(n)	Income Taxes:

The Company accounts for income taxes under the provisions of Statement of Financial Accounting Standards No. 109, “Accounting for Income Taxes” (FAS 109). Under FAS 109, deferred tax assets and liabilities are determined based on the difference between the financial statement carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse.

Effective January 1, 2007, we adopted the Financial Accounting Standards Board (“FASB”) Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 (“FIN 48”). FIN 48 prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken, or expected to be taken, in a tax return. FIN 48 also provides guidance related to, among other things, classification, accounting for interest and penalties associated with tax positions, and disclosure requirements. Any interest and penalties accrued related to unrecognized tax benefits will be recorded in tax expense. The adoption of FIN 48 had no impact on the Company’s financial statements for the year ended December 31, 2007.

(o)	Earnings Per Share

The following weighted average shares were used for the computation of basic and diluted earnings per share:

	For the years ended
	December 31, 2008	December 31, 2007
Basic	61,266,954	14,608,478

Diluted	61,266,954	14,608,478

Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution from the exercise or conversion of other securities into common stock, but only if dilutive. Diluted loss per share for the years ended December 31, 2008 and 2007 is the same as basic loss per share, since the effects of the calculation were anti-dilutive due to the fact that the Company incurred losses for all periods presented. The following securities, presented on a common share equivalent basis, have been excluded from the per share computations:

	For the years ended
	December 31, 2008	December 31, 2007

(p)	Recent Accounting Pronouncements Affecting the Company:

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“FAS”) No. 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. This statement does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. FAS No. 157 is effective for fiscal years beginning after November 15, 2007, and all interim periods within those fiscal years. In February 2008, the FASB released FASB Staff Position (FSP FAS 157-2 – Effective Date of FASB Statement No. 157) which delays the effective date of FAS No. 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), to fiscal years beginning after November 15, 2008 and interim periods within those fiscal years. The implementation of FAS No. 157 for financial assets and liabilities, effective January 1, 2008, did not have an impact on the Company’s financial position and results of operations. The Company is currently evaluating the impact of adoption of this statement on its nonfinancial assets and liabilities which is expected to be determined by the first quarter of fiscal 2009.

In February 2007, the FASB issued FAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“FAS No. 159”). FAS No. 159 permits entities to choose to measure, on an item-by-item basis, specified financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected are required to be reported in earnings at each reporting date. FAS No. 159 is effective for fiscal years beginning after November 15, 2007, the provisions of which are required to be applied prospectively. The Company adopted this statement as of January 1, 2008 and has elected not to apply the fair value option to any of its financial instruments.

DECEMBER 31, 2008 AND 2007

In December 2007, the FASB issued FAS No. 141 (revised 2007), Business Combinations, which replaces FAS No 141. The statement retains the purchase method of accounting for acquisitions, but requires a number of changes, including changes in the way assets and liabilities are recognized in the purchase accounting. It also changes the recognition of assets acquired and liabilities assumed arising from contingencies, requires the capitalization of in-process research and development at fair value, and requires the expensing of acquisition-related costs as incurred. FAS No. 141R is effective for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. The adoption of FAS 141R is not expected to have an impact on the Company’s financial statements.

In December 2007, the FASB issued FAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements – an Amendment of ARB No. 51.” FAS 160 establishes accounting and reporting standards pertaining to ownership interests in subsidiaries held by parties other than the parent, the amount of net income attributable to the parent and to the noncontrolling interest, changes in a parent’s ownership interest, and the valuation of any retained noncontrolling equity investment when a subsidiary is deconsolidated. This statement also establishes disclosure requirements that clearly identify and distinguish between the interests of the parent and the interests of the noncontrolling owners. FAS 160 is effective for fiscal years beginning on or after December 15, 2008. The adoption of FAS 160 is not currently expected to have a material effect on the Company’s consolidated financial position, results of operations, or cash flows.

In March 2008, the FASB issued FAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities – an Amendment of FASB Statement No. 133.” The new standard is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity’s financial position, financial performance, and cash flows. It is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. The Company is currently evaluating the impact of adopting FAS No. 161 on its financial statements.

In December 2007, the Emerging Issues Task Force (“EITF”) reached a consensus with respect to Issue No. 07-1 “Accounting for Collaborative Arrangements”. This EITF applies to participants in a collaborative arrangement. A collaborative arrangement is a contractual arrangement that involves a joint operating activity. These arrangements involve two (or more) parties who are both (a) active participants in the activity and (b) exposed to significant risks and rewards dependent on the commercial success of the activity. Many collaborative arrangements involve licenses of intellectual property, and the participants may exchange consideration related to the license at the inception of the arrangement. Participants in a collaborative arrangement shall report costs incurred and revenue generated from transactions with third parties (that is, parties that do not participate in the arrangement) in each entity's respective income statement pursuant to the guidance in EITF No. 99-19. An entity should not apply the equity method of accounting under APB 18 to activities of collaborative arrangements. This EITF, which can be applied retrospectively, is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. The guidance in this EITF is not expected to have an impact on the Company’s financial statements.

In June 2007, EITF reached a consensus with respect to Issue No. 07-3 “Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities”. EITF 07-3 confirms that nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities should be deferred and capitalized. Such amounts should be recognized as an expense as the related goods are delivered or the related services are performed. If an entity does not expect the goods to be delivered or services to be rendered, the capitalized advance payment should be charged to expense. This EITF is effective for financial statements issued for fiscal years beginning after December 15, 2007. The guidance in this EITF had no impact on the Company’s financial statements in 2008.

Under the terms of the SOP, the Compensation Committee of the Company’s board is authorized to grant incentive options to key employees and to grant non-qualified options to key employees and key individuals. The options become exercisable at such times and under such conditions as determined by the Compensation Committee. The SOP was amended at the Company’s 2005 stockholders’ meeting. The number of options under the SOP was increased to cover 3,000,000 shares of common stock. It was also amended to allow independent directors to be eligible for grants under the portion of the SOP concerning non-qualified options.

Effective June 3, 2008, the Company’s stockholders voted to approve the 2008 Stock Incentive Plan (“SIP”). Under the terms of the SIP, the Compensation Committee of the Company’s board shall have the discretion to select the persons to whom Awards are to be granted. Awards can be incentive stock options, restricted stock and/or restricted stock units. The Awards become vested at such times and under such conditions as determined by the Compensation Committee.

As a result of the adoption of FAS 123(R), the Company's results for the years ended December 31, 2008 and 2007 include share-based compensation expense totaling $263,000 and $252,000, respectively. Such amounts have been included in the Consolidated Statements of Operations within cost of goods sold ($19,000 and none, respectively), research and development ($56,000 and $100,000, respectively) and selling, general and administrative expenses ($188,000 and $152,000, respectively). No income tax benefit has been recognized in the income statement for share-based compensation arrangements due to the history of operating losses.

Stock option compensation expense in the years ended December 31, 2008 and 2007 represent the estimated fair value of options outstanding which are being amortized on a straight-line basis over the requisite vesting period of the entire award.

The weighted average estimated fair value of stock options granted in the years ended December 31, 2008 and 2007 was $.37 and $.46 per share, respectively. The fair value of options at the date of grant was estimated using the Black-Scholes option pricing model. The expected volatility is based upon historical volatility of our stock and other contributing factors. The expected term is determined using the simplified method as permitted by SAB 107, as the Company has no history of employee exercise of options to-date.

The assumptions made in calculating the fair values of options are as follows:

	For the years ended
	December 31, 2008	December 31, 2007
Expected term (in years)	1 to 4	5
Expected volatility	109.33-112.33%	102.84-104.80%
Expected dividend yield	n/a	n/a
Risk-free interest rate	1.91 to 2.98%	4.50-5.06%

The Company granted 967,650 new options under the Plans during the year ended December 31, 2008 at prices ranging from $.13 to $0.22 per share (534,000 were issued under the SOP and 433,650 were issued under the SIP). As of February 15, 2008, the board of directors voted to re-price any SOP options in excess of $.48 to $.48, the estimated expense related to this re-price is $20,000.

DECEMBER 31, 2008 AND 2007

The Company produces only one group of similar products known collectively as “rapid medical tests”. As per the provisions of FAS 131, management believes that it operates in a single business segment. Net sales by geographic area are as follows:

	For the years ended
	December 31, 2008		December 31, 2007
Africa	$	4,740,858	$	3,784,791
Asia		227,049		158,577
Europe		160,824		153,808
Middle East		308,053		239,838

South America		2,503,640		201,421
	$	10,355,768	$	8,764,877

Sales to Africa in 2008 were primarily from Nigeria of approximately $2.86 million. We have been advised recently that our designation in Nigeria as one of the screening tests has changed to that of the confirmatory test as this country moves from a parallel to a serial testing algorithm, which we expect will significantly reduce our sales to Nigeria in 2009, In addition sales to North America and South America in 2008 were primarily from sales into the U.S. and Brazil, respectively.

DECEMBER 31, 2008 AND 2007

As of the filing date of this Annual Report, the Company is in discussion for a lease extension for its administrative offices and research facilities. The principle terms being discussed are as follows: (a) a lease term of five years; (b) an initial rent of $11,350 per month; (c) the monthly rent for year two of the lease will increase by the lower of (i) the change in the consumer price index, or (ii) five percent; and (d) the monthly rent for years three through five of the lease will increase each year by the lower of (i) the change in the consumer price index, or (ii) two and one half percent. Although the Company believes that the extension will be entered into on terms that are substantially similar to the terms being discussed, there is no assurance that this will occur. After this lease is executed the following would be the schedule of future minimum rental commitments (assuming 5% increase the first year and 2.5% thereafter):

In the table above the asterisk (*) indicates that purchases from the vendor’s did not exceed 10% for the period indicated.

The Company currently buys materials which are purchased under intellectual property rights agreements and are important components in its products. Management believes that other suppliers could provide similar materials on comparable terms. A change in suppliers, however, could cause a delay in manufacturing and a possible loss of sales, which would affect operating results adversely.

DECEMBER 31, 2008 AND 2007

Governmental Regulation:

All of the Company’s existing and proposed diagnostic products are regulated by the United States Food and Drug Administration (FDA), United States Department of Agriculture, certain state and local agencies, and/or comparable regulatory bodies in other countries. Most aspects of development, production, and marketing, including product testing, authorizations to market, labeling, promotion, manufacturing, and record keeping are subject to review. After marketing approval has been granted, Chembio must continue to comply with governmental regulations. Failure to comply with these regulations can result in significant penalties.

Voluntary Component Recall:

In April 2008, we initiated a voluntary recall of two lots of Control kits used with our HIV 1-2 Stat Pak® Assay distributed by Inverness under its Clearview® brand. Control kits are to be used in order to verify the operator’s ability to properly perform the test and to interpret the results. These kits are supplied directly to Inverness by our vendor in accordance with our specifications and instructions. In the case of these two lots of Control kits, although they met our specifications, they were at the lower limit of such specifications, and this produced some issues with the interpretation of the Control kit results by certain customers. Chembio has provided the kit supplier with a more clearly defined specification and has reviewed copies of revised manufacturing and testing procedures to ensure implementation of the new specification. Based upon this new specification, packaged HIV Rapid Test Control Packs containing the new HIV Controls have been in distribution since May 2008. The FDA has classified this voluntary recall as a Class II recall, “a situation in which the use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences are remote”. Approximately $22,000 in costs were incurred in 2008. We have completed all of our recall activity, including monitoring and final product disposition and the FDA has issued a letter to the Company confirming that this investigation is officially closed.

Nigeria:

During the first quarter of 2008, the Nigerian Ministry of Health published a report indicating that our designation in Nigeria as one of the screening tests would be changed to that of a confirmatory and/or tie-breaker test (Many countries use a serial algorithm with tests from different manufacturers. A serial algorithm uses a screening test from one manufacturer, a second confirmatory test, from another manufacturer, if there is a positive result from the screening test, meaning that the number of confirmatory tests used is equal to the positivity rate in the testing venue. A tie-breaker test, from a third manufacturer, resolves discrepancies between the screen and the confirmatory test) which change has become effective in the first quarter of 2009. Consequently we expect our sales to Nigeria to decrease significantly in 2009 as compared to 2008.
