Response Genetics Secures New York State Department of Health Approval for the Company's ResponseDX(R) Testing Services

Response Genetics, Inc. (Nasdaq:RGDX), a company focused on the development and sale of molecular diagnostic tests that help determine a patient's response to cancer therapy, received approval from the New York State Department of Health to offer, market and report results of the Company's ResponseDX® tests to healthcare providers in the State of New York. The State of New York is the third most populated state in the U.S. and the addition of this license should contribute to the continued growth of the Company's ResponseDX® sales in 2015.

New York is the only U.S. state that requires an independent regulatory review process including clinical and technical evaluation for laboratory developed tests. It conducts one of the most demanding investigations including validation of laboratory developed tests and an on-site inspection of each laboratory seeking a New York State clinical laboratory permit. The State's review of the Company was completed after the Company met all of the State's regulatory requirements including a two-day inspection of the Company's CLIA certified laboratory on September 23rd and 24th of this year.

Thomas A. Bologna, the Company's Chairman & Chief Executive Officer stated, "We are extremely pleased to have received approval to market and sell our ResponseDX® testing services in New York State. Recently, we announced that our third quarter 2014 ResponseDX® revenue set another record related to the Company's quarterly ResponseDX® sales. With the expansion of our available market to include New York State, we expect to continue to increase the growth of our ResponseDX® sales."
