Chembio Initiates Pre-IDE Studies for Home Use of Sure Check(R) Rapid HIV Test

MEDFORD, NY--(Marketwire - 06/27/11) - Chembio Diagnostics, Inc. (OTCQB: CEMI) (OTC.BB:CEMI - News) ("Chembio" or the "Company"), which develops, manufactures, markets and licenses point-of-care diagnostic tests, has initiated studies required for submission of an Investigational Device Exemption (IDE) to the Food and Drug Administration for its Sure Check® rapid HIV Test as the first step toward over-the-counter (OTC) product approval. This is the first of Chembio's FDA-approved rapid HIV tests that it will target for the at-home market.The first step toward approval is to submit an investigational device exemption (IDE). Chembio believes that a market study of the intended users and an additional "Flex" Study are required to complete the IDE submission. Both of these studies have been initiated and Chembio plans to complete both of these studies and submit an IDE to the FDA during the latter part of this year. Chembio will be requesting a meeting with the FDA to confirm and further clarify the process prior to submitting an IDE.Lawrence Siebert, CEO of Chembio Diagnostics, commented, "Today is National HIV Testing Day, and it is important to realize that the need for a simple at-home rapid HIV test is still unfulfilled. Approximately 20 percent of Americans with HIV are unaware of their infected status according to the CDC. Our test will empower individuals who don't have access to point-of-care testing, or who are afraid to take the test in a public setting, to get the information they need to make informed decisions, including getting early access to increasingly effective therapeutic treatments. We believe that our Sure Check® HIV system is convenient, cost effective and reliable, and that by addressing this additional market segment we will help to achieve the important public health objective of increasing awareness of HIV status."The Sure Check® HIV test is a finger-stick whole blood test that is unique in how easy it is to use and provides results in just 15 minutes. This is by no means the first at-home test that uses blood samples; many diabetes and coagulation monitoring tests currently use blood samples. Chembio believes that its test will be as acceptable to the general public as these other tests that have been widely used in the home testing market.Chembio's Sure Check® HIV test uses a "barrel" system that is easy to use and should be accepted for self-testing based upon its growing success in the professional market, such as public health testing clinics. The barrel system contains a sample port at one end of the barrel which houses the HIV test strip. The small blood sample (only 2.5 micro liters required) enters the barrel simply by touching the sample port to the fingertip pricked with the provided safety lancet. The "barrel" technology confines the sample and reagents, thereby minimizing potential exposure to the user or other parties.

The HIV 1/2 Stat-Pak® Assay, Chembio's other FDA-approved lateral flow rapid HIV test, also received approval for hospitals and clinics on May 25, 2006. To date, these represent two of the four FDA-approved rapid HIV tests in the U.S. market. Chembio's patented Dual Path Platform (DPP®) HIV test, for use with oral fluid or blood samples, is currently in clinical trials. Also in development with Chembio's DPP® technology are DPP® Syphilis, DPP® Hepatitis C and DPP® Influenza tests.About Chembio DiagnosticsChembio Diagnostics, Inc. develops, manufactures, licenses and markets proprietary rapid diagnostic tests in the growing $7 billion point-of-care testing market.
