QuantRx(R) Biomedical Announces Patent Issuance Related to Collection Device of Oral Fluids in Medical Diagnostic Tests

DOYLESTOWN, PA -- (MARKET WIRE) -- October 10, 2006 -- QuantRx® Biomedical Corporation (OTCBB: QTXB), an emerging leader in the research and development of medical diagnostic platforms and products, today announced that the United States Patent and Trademark Office has issued U.S. Patent 6,998,273 relating to an innovative QuantRx device that enables collection of oral fluids in a lateral flow device.

The patent covers the QuantRx oral fluid collection device specifically designed for rapid lateral flow tests -- the only one-step oral fluid testing device now on the market. It was developed by QuantRx for use with its patented RapidSense® technology.

The new QuantRx patented device has applications in the growing market for fluid-sample collection for issues ranging from drug-abuse testing, biological evidence for criminal investigation, screening for numerous communicable diseases including HIV/AIDS and other STDs, as well as other health concerns.

The QuantRx device -- an industry first -- incorporates a removable barrier that prevents test chemicals from washing into the oral cavity during the collection process, and allows the controlled start of the test or tests within the device.

Because the innovative lateral flow collection device is designed for either a single test or multiple tests using the same sample, it is ideal for emerging drugs of abuse testing and HIV testing. Additionally, the patented technology has a feature that provides a more secure "chain of custody" system, helping to ensure the identity and integrity of a specimen from collection through the reporting of test results.

"We are pleased to add another patent to the growing QuantRx Biomedical portfolio of intellectual property. It is especially gratifying for us to be able to bring to market this novel one-step oral fluid testing device, which addresses important and numerous challenges in medical testing, especially those presented by HIV/AIDS and other sexually transmitted diseases," Walter Witoshkin, QuantRx president and chief executive officer, said, adding that the company's overall plans call for the 2007 introduction of tests based on this innovative technology.
