Hair ETG Alcohol Test: How It Works | AMH Nationwide
Understanding Hair ETG Alcohol Test How It Works for Reliable Alcohol Detection
The hair ETG alcohol test how it works involves collecting a small hair sample to detect ethyl glucuronide, a direct alcohol metabolite, providing a detection window of up to 90 days. Samples are sent to national labs for screening, confirmation, and Medical Review Officer evaluation. Call (877) 731-6362.
What is the hair ETG alcohol test and how does it work?
The hair ETG alcohol test detects ethyl glucuronide (ETG), a direct metabolite of alcohol, deposited in hair strands. This test works by analyzing a small hair sample to reveal alcohol consumption over a period of up to 90 days. The ETG compound binds to hair keratin, allowing labs to identify alcohol use well beyond the short detection windows of blood or urine tests.
How is the hair sample collected for the ETG alcohol test?
Hair sample collection for the ETG alcohol test involves cutting a small amount of hair close to the scalp, typically from the crown or back of the head. The sample size is usually about 100 strands or roughly 1.5 inches in length to cover the standard detection window. This collection is performed at authorized collection sites designated by AMH Nationwide.
What happens during lab analysis of the hair ETG alcohol test?
Upon receipt, the hair sample undergoes a multi-step laboratory analysis. Initially, a screening test identifies the presence of ETG using immunoassay or similar methods. Samples that test positive or inconclusive then proceed to confirmatory testing using gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) to precisely quantify ETG levels.
How is the hair ETG alcohol test result verified and reviewed?
Every non-negative hair ETG test result undergoes review by a certified Medical Review Officer (MRO). The MRO evaluates laboratory findings alongside any relevant medical history or prescription information to rule out false positives or alternative explanations. This ensures the final test report is accurate and medically sound.

AMH Nationwide coordinates your test by providing the lab order and directing you to a nearby collection site within our five national lab networks. Contact us to begin the process. Call (877) 731-6362.
Which laboratories process the hair ETG alcohol test samples?
Hair ETG alcohol test samples collected through AMH Nationwide are routed to one of five national laboratory networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. These labs follow strict chain-of-custody and testing protocols to guarantee reliable and compliant results.
Is the hair ETG alcohol test suitable for DOT-regulated testing?
The hair ETG alcohol test is not used for Department of Transportation (DOT) safety-sensitive testing, which requires federally certified urine testing under 49 CFR Part 40. Hair ETG testing is primarily applied in non-DOT contexts where long-term alcohol monitoring is needed.
Common Questions
The hair ETG alcohol test can detect alcohol consumption for up to 90 days, as ETG accumulates in hair strands over time. This extended detection window allows for long-term monitoring compared to urine or blood tests.
Approximately 100 hair strands about 1.5 inches in length are collected close to the scalp, usually from the crown or back of the head, to provide sufficient material for accurate ETG analysis.
Initial screening uses immunoassay techniques, and any positive or inconclusive results are confirmed with gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) for precise ETG quantification.
A certified Medical Review Officer (MRO) reviews all non-negative results to verify accuracy and consider medical explanations, ensuring the final report is reliable and medically validated.
No, DOT-regulated testing requires federally certified urine testing under 49 CFR Part 40. The hair ETG test is intended for non-DOT settings requiring long-term alcohol use detection.
