Pathology, Inc. and CombiMatrix Expand Partnership in Prenatal Testing Market

CombiMatrix Becomes Exclusive Provider of Testing for Products of Conception

IRVINE, Calif., June 20, 2013 (GLOBE NEWSWIRE) -- CombiMatrix Corporation
(Nasdaq:CBMX), a molecular diagnostics company performing DNA-based testing
services for developmental disorders and cancer, today announced that it has
been selected by Pathology, Inc. to be its exclusive provider of chromosomal
microarray tests for the Products of Conception (POC) testing market
throughout the United States. POC testing, also referred to as miscarriage
testing, is a subset of the overall prenatal testing market.

The announcement is an expansion of the previous strategic partnership between
the two companies announced in November 2012 that gave Pathology, Inc. the
right to market and distribute microarray tests on behalf of CombiMatrix in
the states of California and Nevada, as well as the St. Louis and Chicago
metropolitan areas.

"The partnership has been very beneficial for both parties to date, and I
believe it will benefit our physician partners and their patients to extend
the working relationship we have established with CombiMatrix," said Vicki
DiFrancesco, President and CEO of Pathology, Inc., a full service, independent
Women's Health laboratory based in Torrance, California. "The POC market is an
important segment of women's health for Pathology, Inc. and we are pleased to
be working with an advanced laboratory like CombiMatrix that specializes in
microarray testing. We believe this market is going to continue to expand as
our physician customers and their patients realize the importance of
microarray testing in helping to identify the causes of miscarriages and how
that information may assist in future pregnancies."

CombiMatrix President and Chief Executive Officer Mark McDonough said, "The
expansion of this partnership underscores the rapidly expanding importance of
microarray testing and the value our team brings to Pathology, Inc. in terms
of operational and analytical support.Pathology, Inc. is one of the leading
women's health labs in the nation and we are very pleased to be recognized by
these experts as a valuable partner.

"Working closely with Pathology, Inc. allows us to extend our customer base of
OB/GYNs and provides us with additional marketing and distribution support.
Our relationship will only become more important as the national healthcare
market learns about the benefits of chromosomal microarray testing," continued
