CombiMatrix Granted Conditional Approval From New York State Department of
Health to Market Prenatal Miscarriage Analysis Test

Opens Large New Market for Leading Growth Product

IRVINE, Calif., June 25, 2013 (GLOBE NEWSWIRE) -- CombiMatrix Corporation
(Nasdaq:CBMX), a molecular diagnostics company performing DNA-based testing
services for developmental disorders and cancer diagnostics, today announced
that its chromosomal microarray analysis (CMA) test for miscarriage analysis
has received conditional approval from the New York State's Department of
Health for testing on patient samples from the state. With nearly 20 million
people, New York is the third most populated state in the nation, behind only
California and Texas.

The Company's CMA test for miscarriage analysis, also called a Product of
Conception (POC) test, is currently CombiMatrix's fastest growing test in
terms of volumes. CombiMatrix previously announced on June 18^th that volumes
from both of its prenatal CMA tests have increased significantly in the past
six months following the publication of data from two National Institutes of
Health (NIH) studies showing the superiority of CMA over traditional
karyotyping for identifying clinically significant genetic abnormalities.

"Gaining the conditional license and ultimately the final approval to market
and sell our POC test throughout New York is an important milestone for us
that will allow us to broaden the market for our number one growth product,"
said CEO Mark McDonough. "As approved under the conditional license, we will
now begin to sell directly to customers and to seek distribution partnerships
to leverage our internal sales force. This could be a tremendous opportunity
for us and, we believe, for the physicians and patients in New York."
