How does our Hair Drug Test compare to urinalysis or saliva tests on the market?
The primary differences are historical use (approximately 90 days dependent on hair length) and the inability to tamper or contaminate the test and therefore directly change the test results. Cocaine, Methamphetamine, Opiates and Phencyclidine are rapidly excreted and usually undetectable in urine 72 hours after use, and in saliva 48 hours after use. The detection period for hair is limited only by the length of the hair sample and is approximately 90 days.
