Call (877) 731-6362 for testing info and scheduling. --- Hair ETG alcohol test for DOT trucking detects ethyl glucuronide in hair to monitor alcohol use over months, supporting compliance with non-DOT hair testing policies in trucking. The test is processed through national labs with MRO review ensuring accuracy. Call (877) 731-6362 to schedule your test or learn more. OVERVIEW ## What is the Hair ETG Alcohol Test for DOT Trucking? The Hair [ETG](https://amhnationwide.com/hair-etg-alcohol-test/) Alcohol Test for DOT trucking measures ethyl glucuronide (ETG), a direct metabolite of alcohol, deposited in hair strands. Unlike [urine](https://amhnationwide.com/urine-drug-testing/) ETG tests that detect alcohol use within 2-3 days, hair ETG testing provides a [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) of up to 90 days or longer, making it suitable for long-term alcohol monitoring. For DOT-regulated safety-sensitive trucking positions, the federal standard requires urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). However, hair ETG testing is used primarily for non-DOT compliance or employer-initiated monitoring where extended detection is necessary. This test is ordered through AMH Nationwide, which coordinates collection at one of over 20,000 nationwide sites. Samples undergo chain of custody procedures and lab analysis at one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. Every non-negative test undergoes review by a certified Medical Review Officer (MRO) to verify results and provide expert interpretation relevant to trucking compliance policies. ORDERING PROCESS ## How is the Hair ETG Alcohol Test Ordered for Trucking? Employers or authorized requesters contact AMH Nationwide by phone at (877) 731-6362 to initiate the hair ETG alcohol test for trucking purposes. AMH does not support online ordering due to regulatory and chain of custody requirements. After verification of requester credentials and purpose, AMH provides a lab order and directs the individual to a nearby collection site from their extensive national network. Locations include medical offices, certified collection facilities, and specialized testing centers equipped for hair sample collection. This controlled ordering process ensures proper documentation, chain of custody forms, and compliance with federal and employer-specific protocols. It also prevents unauthorized or unsanctioned testing, which could compromise result validity. COLLECTION PROCEDURE ## What is the Hair Sample Collection Process for ETG Testing in Trucking? Hair sample collection for ETG testing in trucking follows strict protocols to maintain chain of custody and sample integrity. A trained collector cuts a small sample of hair, typically near the scalp, from the crown or other approved area. The required sample length is usually 1.5 inches to represent about 90 days of alcohol exposure. The hair must be free of treatments that could alter ETG concentrations, and the collector documents the sample source and quantity. The sample is sealed in tamper-evident packaging with chain of custody forms signed by both collector and donor. This documentation accompanies the sample to the lab to ensure traceability and court-admissibility if needed for regulatory or disciplinary actions. LAB ANALYSIS ## How Do National Labs Process Hair ETG Alcohol Tests for Trucking? After collection, samples are shipped under controlled conditions to one of AMH’s five national lab partners: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. These labs are CAP and CLIA accredited and follow [SAMHSA](https://www.samhsa.gov/workplace/drug-testing) guidelines where applicable. The labs perform quantitative analysis of ETG levels using validated methods such as liquid chromatography-tandem mass spectrometry (LC-MS/MS). The federally recommended cutoff for ETG in hair is typically 30 picograms per milligram, but thresholds can vary by employer policy. Results are reviewed for quality control, and any positive or inconclusive findings trigger confirmation testing. This meticulous process guarantees reliable and reproducible results supporting trucking industry compliance and safety regulations. ## Schedule Your Hair ETG Alcohol Test for Trucking To initiate testing or learn more about requirements and procedures for hair ETG alcohol testing in trucking, call AMH Nationwide at (877) 731-6362.

Every non-negative hair ETG test result is reviewed by a certified Medical Review Officer (MRO). The MRO evaluates the test findings alongside medical history, prescriptions, or legitimate alcohol exposure disclosures that may affect interpretation. This step is critical in trucking employment contexts to avoid false positives and ensure that the result accurately reflects the individual’s alcohol use status relative to job requirements. The MRO communicates verified results to the employer or authorized requester, providing clear explanations and recommendations consistent with DOT or company policies. This process maintains fairness and legal defensibility of testing outcomes. RESULTS & COMPLIANCE ## How Are Hair ETG Test Results Used in DOT Trucking Compliance? Hair ETG alcohol test results provide long-term monitoring data that supplement DOT urine testing programs or serve in non-DOT safety-sensitive trucking roles. Employers use these results to enforce alcohol abstinence policies, [return-to-duty](https://amhnationwide.com/dot-return-to-duty/) decisions, or random testing programs where a longer detection window is necessary. Because hair ETG testing is not federally mandated for DOT urine-based programs, it is typically applied as an additional measure. The documented chain of custody, lab accreditation, and MRO review support results’ admissibility for disciplinary or legal actions related to trucking safety. 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.

Hair ETG testing is used only for non-DOT or additional employer monitoring. Hair ETG testing can detect alcohol use up to 90 days or longer, depending on hair length, providing a longer monitoring period than urine or breath tests. Yes. Chemical treatments like bleaching or dyeing can potentially reduce ETG concentrations in hair. Collectors document hair condition, but labs account for this during analysis. A certified Medical Review Officer (MRO) evaluates any non-negative results to verify accuracy and rule out legitimate explanations before reporting to the employer. Chain of custody is documented from collection through transport to the lab using tamper-evident packaging and signed forms to ensure sample integrity and legal defensibility.
