Hair
Drug Testing

Hair testing has come to be seen as a powerful tool for the detection of drug and alcohol use. Hair provides a long-term history of alcohol and other drug use and/or exposure by trapping substances in the shaft of the growing hair strand. When collected close to the scalp, hair can provide up to approximately a 3-month detection window for alcohol and other drugs.

Hair Drug Testing

A 1.5-inch sample of about 200 strands of hair (about the size of a #2 pencil) closest to the scalp will give 100mg of hair, the ideal sample for screening and confirmation. For EtG, add-ons, and/or tests above 10 panels, 150mg of the specimen is recommended. We recommend weighing the specimen on a jeweler’s scale. If scalp hair is unavailable, an equal amount of body hair may be collected. When referring to head hair, we are referring to scalp hair only. Body hair refers to all other hair types (facial, axillary, etc.).
  • ~3 Month detection window
  • Simple to collect
  • Difficult to adulterate
  • Non-biohazard specimen
