Psychemedics Awarded Patent Fundamental To Hair Analysis Drug Testing

The world’s largest drug testing company using hair analysis received its seventh United States Patent dedicated to liquefying hair to release drug analytes.

Acton, Massachusetts, January 24, 2012 – Psychemedics Corporation (NASDAQ:PMD) , hair testing pioneer and global leader for 25 years, announced today that the United States Patent Office issued a seventh patent, US No. 8,084,215, to the company. This patent focuses on liquefying hair and releasing drugs trapped in the hair without destroying the drugs. The new patented method can be used with a broad range of immunoassay screen techniques, mass spectrometry methods, and chromatographic procedures.

Raymond C. Kubacki, Chairman and Chief Executive Officer, said, “We are pleased to have received this patent which is fundamental to all hair analysis drug testing. This patent covers the efficient digestion of hair and release of the drugs without destroying the drugs—getting virtually 100% of the drug out of the hair. This is fundamental to hair analysis drug testing because if you cannot get the drugs out of the hair, the drugs cannot be measured.” Kubacki continued, “Our ability to successfully release drug analytes from hair enables us to accurately identify more drug users, setting Psychemedics apart from all other hair testing technologies.”

Kubacki added, “Psychemedics Corporation has, for 25 years, offered the most effective hair testing technology based upon scientifically validated drug testing methods. Receiving this patent demonstrates our on-going commitment to achieving the best possible test to accurately identify the greatest number of drug users.”
