Chembio Reports Fourth Quarter and Full-Year 2007 Results

Results Feature Record Revenues for Point-of-Care, Rapid HIV Tests; Conference Call Scheduled for Thursday, March 13 at 10:00 a.m. Eastern Time

MEDFORD, NY--(Marketwire - March 13, 2008) - Chembio Diagnostics, Inc. (OTCBB: CEMI) today reported financial results for the three and twelve months ended December 31, 2007.

Total revenues for 2007 were $9.2 million, an increase of $2.7 million or 42% from total revenues of $6.5 million in 2006. This increase was primarily due to initial sales of Chembio's rapid HIV tests to its U.S. marketing partner, increased sales in Africa, sales to a distributor in Mexico, and increased development and grant revenues, partially offset by lower sales to South America.

Rapid HIV test revenue for 2007 increased $3.5 million to $7.9 million or 79% from $4.4 million in 2006. This includes approximately $2.4 million in revenues realized from sales of rapid HIV tests in the United States.

The net loss attributable to common stockholders was $8.3 million or $0.57 per share for 2007 compared to a net loss attributable to common stockholders of $8.2 million or $0.80 per share for 2006. The net loss attributable to common stockholders for 2007 includes $4.2 million of non-recurring deemed dividends and $1.3 million in non-cash dividends to preferred stockholders. The net loss attributable to common stockholders for 2006 includes $3.0 million in non-cash dividends to preferred stockholders. As previously reported, all of the Company's preferred stock was converted to common stock on December 19, 2007, and no preferred stock dividends are required in the future.

Total revenues for the fourth quarter of 2007 were $2.4 million, a 9% decrease compared with fourth quarter 2006 revenues of $2.6 million. This decrease was primarily due to $1.1 million of revenues from a division of Bio-Rad Laboratories in Mexico and $845,000 in sales to Brazil during the 2006 fourth quarter that did not recur in the 2007 fourth quarter. These items were largely offset by increased rapid HIV test sales in Africa of $740,000, and to sales by the Company's marketing partner in the U.S. of $875,000 during the 2007 quarter, where there were no sales in the 2006 quarter.

The net loss attributable to common stockholders was $5.2 million or $0.32 per share for the fourth quarter of 2007 compared to a net loss attributable to common stockholders of $3.1 million or $0.24 per share for the fourth quarter of 2006. The net loss attributable to common stockholders for the fourth quarter of 2007 includes $4.2 million of non-recurring deemed dividends and $0.25 million in non-cash dividends to preferred stockholders. The net loss attributable to common stockholders for the fourth quarter of 2006 included $1.0 million in non-cash dividends to preferred stockholders.

Fourth Quarter and Recent Highlights

--  Received CLIA (Clinical Laboratory Improvement Act) Waiver for our FDA-
    approved HIV Barrel test, a unique, self-contained rapid HIV test that is
    exclusively marketed worldwide by Inverness Medical Innovations, Inc. as
    Clearview® COMPLETE HIV 1/2. The CLIA waiver allows the sale of these
    rapid HIV tests to a potential market of approximately 189,000 laboratory
    entities across the United States, including physician offices and clinics.
--  Achieved the performance objectives of the feasibility study for the
    Company's Dual Path Platform (DPP™) point-of-care test system entered
    into with Pall Corporation in July 2007. This successful feasibility study
    demonstrated the significant performance advantages of DPP™ over
    conventional single-path lateral-flow design and further defined the value
    proposition that the technology can provide to partners.
--  Completed three new technology transfer, supply and license agreements
    with The Bio-Manguinhos unit of the Oswaldo Cruz Foundation of Brazil for
    products being developed by Chembio with its patented DPP™ technology.
    Internal and external studies demonstrated high sensitivity and specificity
    for Chembio's DPP™ assays for Leishmania, Leptospirosis and HIV-1
    confirmatory tests in comparison with conventional single-path, lateral-
    flow technology in screening for infectious diseases. This agreement also
    served to advance the scale-up of DPP™ production capability for future
    DPP™ collaborations.
--  Engaged in funded feasibility studies for DPP technology with
    potential partners.
--  Received certification under ISO (International Organization for
    Standardization) 13.485: 2003, the quality system that is most recognized
    throughout the European Community for products seeking a CE marking.
    Chembio has engaged a European Notified Body in connection with its plans
    to obtain a CE marking for its products.
    

"We are pleased with our many achievements in 2007. We significantly increased our revenues, expanded our gross margins, controlled our overhead costs, advanced our proprietary DPP™ technology and enhanced our production capacity. We expect to build upon this momentum throughout 2008," said Lawrence Siebert, President and CEO. "Our 2007 revenue growth is largely attributable to our entry into the U.S. market. The recent CLIA waiver mentioned above significantly expands the market for this point-of-care diagnostic. In addition, recent recommendations by the U.S. Center for Disease Control and Prevention (CDC) for routine HIV screening of the general population are expected to continue to drive sales of rapid, point-of-care HIV diagnostics."

"During 2007, we made great strides toward advancing our proprietary DPP™ technology. We engaged in a number of feasibility agreements for DPP™, and are optimistic about its future. Our agreements with the Oswaldo Cruz Foundation and agreements in negotiations with others are validating DPP™ and laying the ground work for future DPP™ collaborations," continued Mr. Siebert.

In closing, he stated, "The recent conversion of our outstanding preferred shares to common stock has simplified our capital structure in a manner that we believe will benefit out Company and our shareholders. We would like to thank our loyal and supportive shareholders for the confidence that they have expressed in Chembio during this past year and our employees for their dedication and hard work."
