You can take a hair follicle drug test at one of the many collection sites affiliated with AMH Nationwide’s five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. AMH Nationwide facilitates the lab order and directs you to the nearest approved collection site. We do not offer direct online ordering; scheduling and site location require a phone call. This testing method involves collecting a small hair sample to detect drug use over approximately 90 days, making it a preferred choice for employers, courts, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers, and individuals. TESTING PROCESS ## How does the hair follicle drug test collection work? Hair follicle drug testing requires a trained collector to cut a small sample of hair close to the scalp, usually from the crown area. The sample is then sent to a certified lab for analysis. The collector ensures chain-of-custody procedures and proper labeling to maintain test integrity. AMH Nationwide’s partner labs follow strict protocols to meet [SAMHSA](https://www.samhsa.gov/workplace/drug-testing), CAP, and CLIA standards. Every non-negative screen undergoes review by a certified Medical Review Officer (MRO) to verify results and provide final interpretation. WHO ORDERS ## Who typically orders a hair follicle drug test? Hair follicle drug tests are commonly ordered by employers for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) screening or random testing of safety-sensitive positions, especially when longer detection windows are required. Courts and probation agencies may also request hair testing to monitor compliance over months rather than days or weeks. Individuals may seek hair follicle testing for personal reasons or to meet specific legal or workplace requirements. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## What is the detection window for a hair follicle drug test? Hair follicle drug tests can detect drug use within approximately 90 days prior to collection. This is significantly longer than [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests, which detect recent use only. Hair grows about half an inch per month; labs typically test 1.5 inches of hair to cover this three-month period. Passive exposure to drugs is unlikely to produce a positive result because the test analyzes metabolites incorporated into the hair shaft internally. ## Ready to Schedule Your Hair Follicle Drug Test?
