Psychemedics Corporation is engaged in providing testing services for the detection of drugs of abuse through the analysis of hair samples. The Company’s testing methods utilize a technology that digests the hair and releases drugs trapped in the hair without destroying the drugs. This is fundamental to the entire process because the patented method gets virtually 100% of the drug out of the hair, and if you cannot get the drug out of the hair, you cannot measure it. The Company then performs a custom-designed enzyme immunoassay (EIA) on the liquid supernatant, with confirmation testing by mass spectrometry. The testing services are performed at the Company’s laboratory at Culver City, California.
