A company considered as a pioneer in hair testing announced on Tuesday that it has been issued its 7th United States Patent, which focuses on liquefying hair in order to release drug analytes.
The patent, which was awarded to Psychemedics Corporation, is dedicated to liquefying hair and releasing the drugs trapped in the hair, without destroying the drugs. The method may be used in a broad range of immunoassay techniques, mass spectrometry methods, and chromatographic procedures.
The popularity of hair drug testing is increasing, as it is less invasive than urine testing, is harder to falsify, and has an extended detection window. In addition, it is also more difficult to tamper with the specimen, which can be collected from anywhere on the body. This means that even someone who is bald or shaves his head may undergo hair drug testing.
