A nail [ETG](https://amhnationwide.com/hair-etg-alcohol-test/) alcohol test detects ethyl glucuronide (ETG), a direct metabolite of alcohol, in [fingernail](https://amhnationwide.com/nail-drug-test/) or toenail clippings. This test identifies alcohol consumption over a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) than blood, [urine](https://amhnationwide.com/urine-drug-testing/), or breath tests. It is a non-invasive method used to monitor abstinence or verify alcohol use history. The test is performed by sending collected nail samples to 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. Results are reviewed by a certified Medical Review Officer to ensure accuracy and interpret findings. WHO ORDERS ## Who typically orders the nail ETG alcohol test? The nail ETG alcohol test is commonly ordered by employers, courts, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers, treatment centers, and healthcare providers. It is used to monitor individuals required to abstain from alcohol, such as employees in safety-sensitive roles not regulated by DOT, participants in substance abuse programs, or people under legal supervision. Employers: Compliance and workplace safety monitoring Courts and Probation: Legal alcohol abstinence verification Treatment Programs: Monitoring recovery progress Healthcare Providers: Assessing patient alcohol use history DETECTION WINDOW ## What is the detection window for the nail ETG alcohol test? The nail ETG alcohol test can detect alcohol use over a period of approximately 3 to 6 months. Fingernails and toenails grow slowly, allowing the ETG metabolite to accumulate and provide a longer retrospective detection window compared to urine or blood testing. This extended detection period makes the nail ETG test useful for monitoring long-term abstinence or verifying alcohol use patterns over several months. COLLECTION ## How is the nail ETG alcohol test collected? Collection involves clipping a small amount of fingernail or toenail samples from the individual. The process is non-invasive and can be performed at authorized collection sites affiliated with one of the five national lab networks used by AMH Nationwide. AMH Nationwide coordinates the lab order and directs the requester to a nearby collection site. Nail samples are then securely sent to the laboratory for analysis.
