Chembio Diagnostics Supports Recent USPSTF Routine Testing Recommendations

MEDFORD, N.Y., May 2, 2013 (GLOBE NEWSWIRE) -- Chembio Diagnostics, Inc.
(Nasdaq:CEMI), a leader in point-of-care diagnostic tests for infectious
diseases, today announced the Company's support for the U.S. Preventive
Services Task (USPSTF) new recommendations for HIV testing of all adults aged
15-65, regardless of their risk, as published on April 29, 2013 and printed in
the Annals of Internal Medicine.

The new guidelines from the USPSTF, a government-backed panel of doctors and
scientists, now align with longstanding recommendations by the U.S. Centers
for Disease Control and Prevention for testing of all adults aged 15 to 65,
regardless of their risk.

Guidelines issued by the USPSTF in 2005 had recommended HIV screening for
high-risk individuals. Experts said the change will likely trigger coverage
for the tests as a preventive service under the Affordable Care Act. Under
President Barack Obama's healthcare law, insurers are required to cover
preventive services that are recommended by the task force.

"We fully support the new USPSTF HIV testing recommendations, as they should
help to lower overall health care costs by the early identification of those
infected.Early diagnosis helps decrease the spread of these infectious
diseases and promotes early access to care, which reduces the need for more
costly late-stage treatments," said Lawrence Siebert, President and Chief
Executive Officer of Chembio Diagnostics, Inc. "As a result of the
recommendations, it is expected that more individuals will get tested and
learn their HIV status. We believe our current and in-the-pipeline rapid,
point-of-care diagnostic testing products for the detection of HIV, as well as
our tests for other infections that can be related to these, such as Syphilis,
will serve important roles in achieving the goals of the recommendations."
