Chembio Launches U.S. Sales and Marketing Initiative

Chembio Now Marketing HIV 1/2 STAT-PAK(R) and DPP(R) HIV 1/2 Assays

MEDFORD, N.Y., June 4, 2014 (GLOBE NEWSWIRE) -- Chembio Diagnostics, Inc.
(Nasdaq:CEMI), a leader in point-of-care (POC) diagnostic tests and
technology, today announced the launch of the Company's U.S. sales and
marketing effort. Effective today, the Company has initiated sales of its
Chembio HIV 1/2 STAT-PAK^® Assay and its corresponding HIV Rapid Test Control
Pack, as well as the Company's proprietary DPP^® HIV 1/2 Assay and
corresponding DPP^® HIV 1/2 Control Pack in the United States. The Company has
also assumed all customer and technical support for its Chembio-branded
products in the U.S.

The Chembio HIV 1/2 STAT-PAK^® Assay is FDA-approved and CLIA-waived and has
been one of the leading diagnostics in the fight against HIV/AIDS since its
market introduction in 2006. The ease of use, small (5 µL) specimen
requirement, rapid and reliable results, long shelf life and room temperature
storage make it uniquely suited for clinical and outreach settings, allowing
immediate patient counseling and referral.

Chembio's DPP^® HIV 1/2 Assay detects HIV antibodies in oral fluid or blood
and uses our patented Dual Path Platform technology which offers excellent
sensitivity and specificity. Its unique SampleTainer^® specimen collection
bottle is a safe, closed system for collecting potentially infectious samples.
The Chembio DPP^® HIV 1/2 Assay is FDA-approved and initial marketing of this
product will be directed to CLIA moderately complex testing sites. We are
working with the FDA concerning CLIA waiver for this product, and are
submitting additional information needed for the FDA's further review of the
application.

"We believe that Chembio has established a world-class sales and marketing
organization," stated John Sperzel, Chembio's CEO. "I'm confident that our
U.S. program will bring us closer to our customers and enable us to strengthen
our position in the market. Our HIV 1/2 STAT-PAK^® Assay is one of the most
reliable and respected HIV diagnostics in the U.S., and we hope to leverage
our reputation for quality and innovation as we introduce our proprietary Dual
Path Platform (DPP^®) diagnostics to the market."

The Chembio HIV 1/2 STAT-PAK^® Assay, which was previously marketed in the
U.S. exclusively as Clearview^® HIV 1/2 STAT-PAK^® Assay, has not undergone
any changes in format or formulation. Both the HIV 1/2 STAT-PAK^® Assay and
the DPP^® HIV 1/2 Assay will continue to be manufactured exclusively at
Chembio's FDA-registered, cGMP compliant and ISO 13485 certified facility in
Medford, NY. For more information on any of the Chembio-branded products
including the Chembio HIV 1/2 STAT-PAK^® Assay, please contact our customer
service team at 1.844.CHEMBIO or visit us at: www.chembio.com.
