Hair tests detect drug use over the past 90 days and are performed by Quest Diagnostics. As with urine testing, all paperwork is digital and the employee or applicant brings their script or registration number and a valid government photo to the testing center. BCGSmartCheck can schedule the appointment for the specimen collection or the applicant can go as a walk in. Test results are reported within 1 business day (if negative) and could take 2 to 3 business days (if positive).
When compared with urine testing, hair testing provides nearly twice the number of positives due to its longer detection window. This test reveals the use of any of the following five types of drugs: Amphetamines/ Methamphetamines (including Ecstasy), Opioids (including Codeine, Morphine, Heroin and semi-synthetic opiates), Cocaine, Marijuana, and Phencyclidine (PCP).
