Hair Follicle Testing

Service Description

This test is performed by collecting a small sample of hair, usually cut from the crown area of the head. Only a small amount is needed, and the collection is discreet and painless. Hair testing detects long-term drug use (typically up to 90 days) and is often used for court, workplace programs, and individuals needing extended-window detection. The sample is sealed and sent to the laboratory for testing.
