Hair Follicle Testing


What is Hair Follicle Testing?

Hair follicle testing is a process in which a small hair sample is collected from a donor's head or body is screened for the use of illicit substances. Hair follicle testing detects people who choose a lifestyle of drug use as opposed to one off use. Testing provides a history and longer detection periods than any other drug testing methods.

Hair growth is fed by the bloodstream, drug metabolites taken orally, via injection, snorted, or smoked, are delivered into each hair strand via the bloodstream and embedded inside the hair shaft. Hair analysis can accurately detect drugs used up to 90 days prior to the test. Each 3.8cm sample of hair provides a 90-day history of drug use.
