A 17-panel hair follicle drug test screens for 17 classes of commonly misused substances, including both illicit drugs and prescription medications with a high potential for misuse. Compared to a standard 5- or 10-panel test, the 17-panel test provides a far more complete view of drug use history.
It is frequently used in legal proceedings, workplace compliance programs, child custody cases, and by individuals who want clear documentation of drug use or sobriety. Because hair testing is difficult to adulterate, it is one of the most trusted methods for accurate results.
