Call (877) 731-6362 to schedule your test or get more information. OVERVIEW ## Does Prime do hair follicle test? Prime does not perform hair follicle drug testing directly. Hair follicle tests are conducted by specialized laboratories with the equipment and accreditation to analyze hair samples for drug metabolites. AMH Nationwide facilitates hair follicle testing by directing clients to collection sites that send samples to one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. If you need a hair follicle test for employment, court, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/), or personal reasons, contact AMH Nationwide at (877) 731-6362. We provide lab orders and collection site referrals but do not offer online ordering. TESTING DETAILS ## What is hair follicle drug testing and how does it work? Hair follicle drug testing detects drug use by analyzing a small sample of hair, usually about 1.5 inches long, which reflects drug intake over approximately 90 days. This method identifies drug metabolites deposited in the hair shaft from the bloodstream. Hair follicle tests are more resistant to adulteration and provide a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) than [urine](https://amhnationwide.com/urine-drug-testing/) tests. Detection window: up to 90 days Sample size: about 100 strands or 1.5 inches of hair Commonly tested drugs: marijuana, cocaine, opiates, methamphetamine, PCP Non-DOT testing method; DOT uses urine testing protocols Hair follicle testing is preferred for non-DOT safety-sensitive positions or for individuals needing a longer-term drug use history. LAB NETWORKS ## Which labs process hair follicle tests through AMH Nationwide? AMH Nationwide routes hair follicle test samples to five nationally recognized lab networks. These labs have the necessary certifications and expertise for hair drug testing. They include: Quest Diagnostics LabCorp Omega Labs United States Drug Testing Labs ExperTox Every non-negative hair follicle test result is reviewed by a certified Medical Review Officer (MRO) to ensure accuracy and proper interpretation.

Hair follicle drug testing is highly reliable due to its longer detection window and resistance to tampering. Unlike urine tests, which detect recent drug use typically within a few days, hair tests can reveal drug use over months. The testing labs used by AMH Nationwide follow strict [SAMHSA](https://www.samhsa.gov/workplace/drug-testing)-aligned protocols and maintain certifications including CAP and CLIA, ensuring trustworthy results. Long detection window up to 90 days Less susceptible to adulteration or substitution Reviewed by certified Medical Review Officers Suitable for employer, court, probation, and individual testing Hair follicle testing is not used for DOT-regulated safety-sensitive testing, which requires federally certified urine protocols under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). COMMON QUESTIONS ## Can hair follicle testing detect passive exposure or be beaten? Hair follicle testing detects drug metabolites incorporated into hair from the bloodstream, not external contamination. Passive exposure to drugs is unlikely to produce a positive result. Attempts to evade or beat hair follicle tests are not supported by science and are discouraged. The testing process includes strict chain of custody and certified laboratory analysis to ensure accuracy. For accurate testing and results, rely on professional collection and certified labs.

Results usually take 3 to 5 business days after the lab receives the sample, depending on the lab’s workload and testing panel. Hair follicle tests commonly detect marijuana, cocaine, opiates, methamphetamine, PCP, and some prescription drugs, but detection depends on the specific test panel requested. No, DOT regulations require urine testing under 49 CFR Part 40. Hair follicle testing is used for non-DOT roles only. A certified Medical Review Officer reviews all non-negative results to verify accuracy and allow for explanation before reporting final results.
