Hair drug testing detects metabolites reliably. Learn the facts. Call (877) 731-6362 for info. --- How to destroy metabolites in hair is a frequent inquiry from those facing hair drug testing. Hair tests detect drug metabolites embedded in the hair shaft, which are not easily removed or destroyed by washing or treatments. Laboratories use sensitive methods reviewed by certified Medical Review Officers to ensure accurate results. Call (877) 731-6362 for guidance on hair drug testing. OVERVIEW ## What are metabolites in hair and why are they tested? Metabolites in hair are chemical substances formed when the body processes drugs. These metabolites become incorporated into the hair shaft from the bloodstream during hair growth. Hair drug testing detects these metabolites to determine past drug use over an extended period, typically up to 90 days. This method is widely used by employers, courts, and [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) agencies for reliable drug detection beyond [urine](https://amhnationwide.com/urine-drug-testing/) or blood tests. DETECTION ## Can metabolites in hair be destroyed or removed? Metabolites in hair cannot be destroyed or removed by normal washing, bleaching, or other hair treatments. Once drug metabolites are embedded inside the hair cortex, they remain detectable. Laboratories use sensitive analytical techniques such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify these metabolites accurately. Attempts to alter hair samples are often detected during laboratory analysis. LAB PROCESS ## How does AMH Nationwide handle hair metabolite testing? AMH Nationwide routes hair samples through five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. Each lab follows strict protocols for hair collection, chain of custody, and testing. Every non-negative screen is reviewed by a certified Medical Review Officer to ensure accuracy and compliance with [SAMHSA](https://www.samhsa.gov/workplace/drug-testing), CAP, and CLIA standards. Hair testing at AMH is for non-DOT regulated roles, as DOT requires urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). LIMITATIONS ## Are there ways to evade hair drug testing by destroying metabolites? Scientific evidence shows that destroying metabolites in hair to evade detection is not feasible. Hair drug testing detects drug use over 1 to 3 months, and metabolites are embedded within the hair structure. Treatments like bleaching or dyeing may reduce metabolite concentration but rarely eliminate them completely. Laboratories are trained to identify altered samples and may reject or invalidate tampered tests. The integrity of hair drug testing remains high for reliable results. ## Need Reliable Hair Drug Testing? Call (877) 731-6362 to schedule hair metabolite testing through AMH Nationwide or for more information.

Hair drug testing can detect metabolites from drug use typically within a 1 to 3 month window depending on hair length. Hair grows about half an inch per month, and labs usually test 1.5 inches closest to the scalp. This window allows detection of drug use beyond the reach of urine or blood tests, which detect more recent use only. This makes hair testing useful for employment, legal, and probation monitoring. ORDERING ## How can I get hair metabolite testing through AMH Nationwide? AMH Nationwide does not provide online ordering. To arrange hair drug testing, call (877) 731-6362. AMH provides the lab order and directs you to one of over 20,000 nationwide collection sites. The sample is collected under chain of custody and sent to one of five national labs for analysis. Results are reviewed by a certified Medical Review Officer. Pricing varies by testing panel and detection window. 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-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). Every non-negative screen is reviewed by a certified Medical Review Officer as part of standard processing before a result is released, and chain-of-custody documentation is maintained on every collection.

Laboratories can detect altered samples and may invalidate such tests. Hair testing detects drug metabolites typically up to 90 days after use, depending on hair length and growth rate. No. DOT-regulated testing requires urine testing under federally certified protocols. Hair testing is used for non-DOT roles. AMH uses five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. Yes.
