Hair Drug Testing
- Employee drug testing of the hair is the only drug test method that provides a detection window of up to 90 days. It is more expensive than urine drug testing and cannot detect recent drug use within 7 days, but because specimen collection is observed, there is little chance of adulteration. Collection, storage and shipping are simple, as specimens do not deteriorate.
Hair drug testing is handled by a certified technician as part of our Mobil, Onsite, and Offsite Testing Services.
