Hair follicle drug testing detects drug metabolites deposited in the hair shaft from bloodstream exposure. It is used to identify drug use over a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) compared to [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests. Hair follicle testing typically detects drug use within the past 90 days. This makes it useful for employers, courts, or [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) agencies who need a historical drug use profile rather than recent or one-time use detection. Detection window: up to 90 days from sample collection Commonly tested substances: marijuana, cocaine, opiates, amphetamines, PCP Sample length: usually 1.5 inches of hair from the scalp Testing method: laboratory analysis with confirmation by certified Medical Review Officer Hair follicle testing is not used for DOT-regulated safety-sensitive positions, which require federally certified urine testing. Hair tests serve non-DOT employment, legal, or personal screening purposes. WHERE TO TEST ## Where can you get a hair follicle drug test done near me?

TESTING PROCESS ## What happens during a hair follicle drug test collection? During a hair follicle drug test, a trained collector cuts a small sample of hair from the scalp, usually about 1.5 inches in length and the diameter of a pencil. The hair sample is sealed in a tamper-evident container and sent to one of the five national labs for analysis. Chain-of-custody procedures are followed to maintain sample integrity. The lab performs initial screening and confirmation testing. Any non-negative results are reviewed by a certified Medical Review Officer to ensure accuracy and interpret findings. Sample length: approximately 1.5 inches of scalp hair Collection by trained personnel at authorized sites Strict chain-of-custody protocols Laboratory analysis with confirmation testing Review of non-negative results by certified Medical Review Officer Call (877) 731-6362 to learn more about the hair follicle collection process or to schedule your appointment. ## Schedule Your Hair Follicle Drug Test Today Call (877) 731-6362 to find a collection site near you and arrange your hair follicle drug testing with AMH Nationwide.

Hair follicle drug testing is designed to detect drug use over a 90-day period and is difficult to evade due to the nature of hair growth and drug metabolite incorporation. Scientific studies show that passive exposure to drugs is unlikely to cause a positive hair test because the lab washes hair samples to remove external contamination. Attempting to alter or substitute hair samples can be detected through chain-of-custody and lab protocols. Laboratories use advanced techniques to ensure sample authenticity. Detection window up to 90 days Lab washes hair samples to remove external contaminants Chain-of-custody prevents sample tampering Certified Medical Review Officers verify non-negative results AMH Nationwide provides reliable hair follicle drug testing with strict lab and collection standards.
