Call (877) 731-6362 to schedule testing or learn more. TEST BASICS ## What does a 5 panel hair follicle test for? A 5 panel hair follicle test screens for five specific drug categories by analyzing a small hair sample. The test detects drug metabolites embedded in the hair shaft, reflecting drug use over approximately 90 days. The five drug classes commonly tested include marijuana (THC), cocaine, opiates, amphetamines, and phencyclidine (PCP). This test is valued for its extended detection period compared to [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests. DETECTION DETAILS ## How long does a 5 panel hair follicle test detect drugs? A 5 panel hair follicle test detects drug use for up to 90 days prior to sample collection. Hair grows about half an inch per month, and the standard 1.5-inch sample captures approximately three months of drug exposure. This long [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) makes hair follicle testing suitable for monitoring long-term drug use patterns rather than recent or one-time use. Approximate detection window: 90 days Sample length: 1.5 inches of hair Detects drug metabolites, not the parent drug TEST PROCESS ## How is the 5 panel hair follicle test conducted? The collection involves cutting a small hair sample close to the scalp, typically from the crown. The sample is then sent to one of five national labs: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. AMH Nationwide coordinates the lab order and directs the requester to a nearby collection site. There is no online ordering; to schedule, call (877) 731-6362. After initial screening, any positive results are reviewed by a certified Medical Review Officer. TEST APPLICATIONS ## Who orders a 5 panel hair follicle test and why? Employers use the 5 panel hair follicle test for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) screening and random drug testing, especially when long-term drug use verification is required. Courts and [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) agencies may also require this test for monitoring compliance. Individuals may request this test for personal monitoring or legal purposes. It is not approved for Department of Transportation (DOT) safety-sensitive positions, which require federally certified urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). ## Schedule Your 5 Panel Hair Follicle Test Today To arrange testing or for more information about what a 5 panel hair follicle test for detects, call (877) 731-6362.

Passive exposure to drugs is unlikely to produce positive results on a 5 panel hair follicle test because the test detects drug metabolites incorporated into the hair shaft from bloodstream circulation, not external contamination. Laboratories follow strict protocols to wash and prepare hair samples to remove external contaminants. This ensures the test results reflect actual drug ingestion rather than environmental exposure. RESULTS AND FOLLOW-UP ## What happens if a 5 panel hair follicle test is non-negative? If the initial screening shows a non-negative result, the sample undergoes confirmatory testing using advanced methods like gas chromatography-mass spectrometry (GC-MS). A certified Medical Review Officer reviews all non-negative results before reporting. This process ensures accuracy and provides an opportunity for the tested individual to explain legitimate medical or legal reasons for the result. AMH Reviewed & Maintained By AMH Nationwide Customer Service AMH Nationwide is BBB A+ accredited and routes every order through Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox, all of which use multiple lab certification agencies and standards such as [SAMHSA](https://www.samhsa.gov/workplace/drug-testing)-aligned laboratory protocols, the ANSI National Accreditation Board for forensic testing and calibration, the College of American Pathologists (CAP), and Clinical Laboratory Improvement Amendments (CLIA).

The test detects specific drug classes, not all medications. Legitimate prescriptions containing tested substances can be disclosed to the Medical Review Officer for evaluation. Yes, many courts, probation agencies, and employers accept this test for its extended detection window and reliability. Results typically take several days to one week, depending on the laboratory and confirmatory testing requirements.
