Forensic Drug Testing Lab
Hair Drug Testing
Recently, hair testing has come to be seen as a powerful tool for the detection of drug and alcohol abuse. Hair provides a long-term history of drug and alcohol abuse by trapping biomarkers in the fibers of the growing hair strand. When collected close to the scalp, hair can provide up to a 3 month history of alcohol and drug abuse. Drug and alcohol biomarkers can appear in scalp hair 1-7 days after the last use. Hair offers a sample that is simple to collect, somewhat difficult to adulterate, and easy to ship. A 1.5 inch sample of about 200 strands of hair (about the size of a #2 pencil) closest to the scalp will give 100 mg of hair, the ideal sample for screening and confirmation. If scalp hair is not available, an equal amount of body hair may be collected.
