World's largest provider of hair testing for drugs of abuse

Collection Methods

One of the major advantages of the Psychemedics hair test for drugs of abuse is the ease of collection. Since collecting the sample only involves snipping a small amount of hair from the back of the head, many Psychemedics customers perform the collection in-house. Psychemedics provides a 20 minute training tape which demonstrates and explains the procedure. The ability to collect the sample in-house is one reason why the Psychemedics drug test can be used anywhere in the world, quickly and easily.

For those customers who prefer an out-of-office sample collection, Psychemedics will recommend a number of TPA (Third Party Administrators) which will provide that service. In either case, compared to a urine test, collecting a hair sample is far easier, and much less intrusive.
