Chembio Diagnostics, Inc. Sponsors 27th Annual AIDS Walk New York as Co-Chair Advocate

MEDFORD, NY--(Marketwire - May 18, 2012) - Chembio Diagnostics, Inc. (OTCQB: CEMI) (PINKSHEETS: CEMI), which develops, manufactures, markets and licenses point-of-care diagnostic tests, today announced that the Company is a proud sponsor and Co-Chair Advocate for the 27th Annual AIDS Walk New York, which takes place this Sunday, May 20th and begins and ends in Central Park.

“We are proud to continue our support of the Annual AIDS Walk New York to increase awareness of HIV and raise funds to support important services. The donations, raised through the collective efforts of tens of thousands of participants, provide medical care, home-delivered meals, women’s and children’s services, educational and preventive services and much more to New York area residents who are affected by AIDS,” said Lawrence Siebert, Chief Executive Officer of Chembio.

Despite the funding and advocacy efforts of community-based organizations such as GMHC and despite current testing options, according to the U.S. Centers for Disease Control and Prevention, there are approximately 1.2 million Americans with HIV and approximately 240,000 of them are unaware of their status. Those who do not know they are HIV positive are unknowingly responsible for up to 70% of the estimated 50,000 new cases of HIV infection that occur each year.

“There continues to be a pressing need for better testing in order to control and prevent the spread of this infectious disease. Consequently, we support the recent unanimous recommendation by members of the U.S. Food and Drug Administration’s Blood Products Advisory Committee (‘BPAC’) in support of an in-home rapid HIV test. We believe the availability of an in-home rapid test to detect HIV will help to increase testing and diagnosis, which in turn will reduce new infections,” noted Mr. Siebert.

Data reported at the BPAC meeting noted that 39% of HIV positive people newly identified by the self-test would not have been identified by conventional HIV testing options.

“Chembio is uniquely positioned to address this need with its unitized Sure Check® HIV 1/2 finger-stick whole blood test. The Sure Check HIV 1/2 test, already FDA-approved and well established in the U.S. market (exclusively distributed by Alere, Inc. in that market as Clearview Complete HIV 1/2), is more sensitive than the recommended oral fluid test. In order to begin the regulatory process toward an over-the-counter market approval for self-testing by consumers, a company must first have a product that is FDA-approved for the professional market, making Chembio the only current practical alternative to the product recommended by BPAC. We are therefore accelerating our development plans to bring our rapid, in-home HIV test to market,” concluded Larry Siebert.
