Chembio Welcomes FDA's Consideration of OTC AIDS Tests

MEDFORD, NY -- (MARKET WIRE) -- October 20, 2005 -- Chembio Diagnostics, Inc. (OTC BB: CEMI) today welcomed news that the FDA Blood Products Advisory Committee (BPAC) will be considering whether and under what conditions it could allow rapid HIV tests to be sold over-the-counter (OTC) to consumers for at home testing. This consideration by BPAC was recently announced by OraSure Technologies, Inc. (OSUR) and reported in the New York Times. OraSure and Chembio are amongst a small group of companies in the US that have or are seeking FDA approval of rapid HIV tests for use in the professional market such as public health clinics and emergency rooms. These tests incorporate technologies that allow the tests to be performed quickly, accurately, and with a minimal number of procedural steps.

Chembio is seeking professional use FDA approval for its Sure Check™ and HIV Stat-Pak™ products. Chembio's management believes that its tests could be well suited for the OTC market if that market becomes available. However, there is no assurance that the FDA will decide to allow OTC marketing of rapid HIV tests. Furthermore, the specific conditions relating to any such allowance can not be known at this time.

"We are immensely pleased that the FDA is considering a process which would make AIDS testing as easy as diabetes and pregnancy testing," said Larry Siebert, Chairman and CEO of Chembio. "Wider access to testing could help identify more positive cases and improve prevention efforts."

Chembio's rapid HIV tests include the HIV 1/2 Stat-Pak™, HIV 1/2 Stat-Pak Dipstick™ and the HIV 1/2 Sure Check™. These tests are simple, safe, cost-effective and operator-friendly requiring less than five microliters of whole blood from a fingerstick.
