Call (877) 731-6362 for testing information. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## How long can alcohol be detected in hair samples? Alcohol can generally be detected in hair for up to 90 days after consumption. This detection window depends on the length of the hair sample collected, usually around 1.5 inches, which represents approximately three months of hair growth. AMH Nationwide directs all hair alcohol testing through five national lab networks, ensuring standardized, accurate testing protocols. The labs analyze hair for [ethyl glucuronide](https://amhnationwide.com/hair-etg-alcohol-test/) (EtG) and fatty acid ethyl esters (FAEEs), biomarkers indicating alcohol consumption over time. Typical detection window: up to 90 days Sample length: about 1.5 inches of hair Biomarkers tested: EtG and FAEEs Testing conducted by [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox TESTING PROCESS ## What is the procedure for alcohol hair testing at AMH Nationwide? AMH Nationwide provides the lab order and directs the requester to a collection site but does not allow online ordering. Collection sites collect hair samples according to strict chain-of-custody protocols. Samples are sent to one of the five national lab networks for analysis. All non-negative results are reviewed by a certified Medical Review Officer (MRO) to confirm accuracy and interpret findings before reporting. WHO ORDERS ## Who typically requires hair alcohol testing? Hair alcohol testing is commonly ordered by employers, courts, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers, and treatment programs to monitor long-term alcohol use. It is useful for safety-sensitive positions where abstinence verification is critical. Individuals may also request hair alcohol testing for personal monitoring or legal reasons. AMH Nationwide supports all requester types with nationwide collection options. TEST RELIABILITY ## Can hair alcohol tests detect occasional or passive alcohol exposure? Hair alcohol tests detect biomarkers indicating actual alcohol consumption rather than passive exposure. Occasional use may be more difficult to detect than chronic or heavy use. The tests are highly reliable when conducted by accredited labs following [SAMHSA](https://www.samhsa.gov/workplace/drug-testing)-aligned protocols. Results are not influenced by environmental exposure, making hair testing a robust option for monitoring. ## Schedule Hair Alcohol Testing with AMH Nationwide Call (877) 731-6362 to begin your hair alcohol testing process.

Hair alcohol testing is not used for Department of Transportation (DOT) regulated alcohol testing. DOT requires federally certified [urine](https://amhnationwide.com/urine-drug-testing/) testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40) for safety-sensitive roles. Hair testing is primarily used in non-DOT contexts for long-term alcohol use monitoring and confirmation. PRICING & CONTACT ## How much does hair alcohol testing cost and how to arrange it?

Passive exposure to alcohol vapor or products does not cause positive test results. No, the DOT requires urine alcohol testing under federally certified protocols.
