Chembio Awarded $750,000 Cooperative Research Agreement

MEDFORD, N.Y., May 23, 2013 (GLOBE NEWSWIRE) -- Chembio Diagnostics, Inc.
(Nasdaq:CEMI) a leader in point-of-care ("POC") diagnostic tests for
infectious diseases, announced today that it has been awarded a cooperative
research agreement with aU.S. government agency for up to $750,000 for an
eight month development project. The project is to develop rapid POC
diagnostic tests for five infectious diseases associated with febrile illness
and to multiplex them into one assay.The project also contemplates that the
test would be optimized for use with a mobile reader that incorporates cell
phone technology to enable the results to be recorded, transmitted and
monitored remotely via a cloud system, in real-time.

Javan Esfandiari, Chembio's Senior Vice President of Research & Development
and the inventor of DPP^®, commented, "We are pleased to be awarded this
research project to develop a complex multiplex assay as it builds on our
strength in developing multiplex products using our proprietary DPP^®
technology. Our DPP^® technology, combined with the mobile reader being used
in the project, will enable real time data collection and monitoring
capabilities. As these infectious diseases can all exhibit similar clinical
symptoms, a rapid multiplex test that could distinguish them would be very
useful, particularly in field conditions, so that correct diagnosis and
treatment could be provided on a timely basis."
