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 drugs by trapping biomarkers in the fibers 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 is simple to collect, somewhat difficult to adulterate, and easy to ship.

Hair anatomy with sweat and body oils

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.).

This is equal to a bundle of hair that is 1.5 inches in length and about ¼ inch in diameter, the diameter of a #2 pencil. For EtG, add-ons, and/or any tests 10-panel and above, at least 150mg of specimen should be submitted. We recommend weighing the specimen on a gem scale.

Turnaround Time: Generally, the standard turnaround time for reporting negative screening test results is the next business day, with an additional 1-2 business days for specimens that require confirmatory testing. Turnaround time begins from receipt of the valid specimen –accompanied by a properly documented valid order– into the laboratory. Some tests require additional time to process and will fall outside the standard turnaround time window.
