What is a 12-month hair drug test which test and how does it work?
A 12-month hair drug test which test detects drug metabolites embedded in the hair shaft, providing a detection window of up to one year. Hair grows approximately half an inch per month, so a 6-inch hair sample can reveal drug use over the previous 12 months. This test is performed by collecting a small hair sample from the scalp, which is then sent to one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox.
The test is highly specific and can detect a range of substances including amphetamines, cocaine, marijuana, opioids, and PCP. Every non-negative result undergoes review by a certified Medical Review Officer to ensure accuracy and proper interpretation.
