For testing through national labs, call (877) 731-6362 to schedule. --- How long does alcohol stay in hair follicles depends on the detection window of ethyl glucuronide (EtG), a direct alcohol metabolite. Hair follicle testing can detect alcohol use typically up to 90 days after consumption. AMH Nationwide uses five national lab networks for reliable analysis. Call (877) 731-6362 for testing information. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## How long does alcohol stay in hair follicles? Alcohol itself is not directly detected in hair follicles. Instead, hair follicle tests measure [ethyl glucuronide](https://amhnationwide.com/hair-etg-alcohol-test/) (EtG), a metabolite formed when the body processes alcohol. EtG can be detected in hair follicles for up to 90 days after alcohol consumption, reflecting long-term drinking patterns rather than recent use. The detection period depends on hair length collected, usually about 1.5 inches representing approximately 90 days of growth. TESTING PROCESS ## What is the process for alcohol hair follicle testing? AMH Nationwide facilitates hair follicle alcohol testing 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. A hair sample is collected at a designated collection site and sent to one of these labs for EtG analysis. Every non-negative result is reviewed by a certified Medical Review Officer (MRO) to ensure accuracy and interpret results within clinical context. Sample: Approximately 1.5 inches of hair from the scalp Analysis: Measures ethyl glucuronide (EtG) in hair Review: Certified MRO reviews all non-negative findings WHO ORDERS ## Who typically orders hair follicle alcohol testing? Hair follicle alcohol testing is often ordered by employers, courts, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers, and treatment programs to monitor long-term alcohol abstinence or use. Individuals may also request testing for personal reasons or to comply with legal or workplace requirements. Because hair testing detects alcohol use over an extended period, it is useful for verifying abstinence or identifying chronic use rather than recent drinking. TEST LIMITATIONS ## Can hair follicle alcohol tests detect one-time or passive exposure? Hair follicle tests detect EtG reflecting sustained or repeated alcohol consumption rather than single isolated events. Passive exposure to alcohol vapors or incidental contact does not produce EtG levels high enough to trigger a positive result. The test is not designed to detect very recent alcohol use, which is better identified through breath, blood, or [urine](https://amhnationwide.com/urine-drug-testing/) testing. ## Schedule Hair Follicle Alcohol Testing Today To arrange hair follicle alcohol testing through AMH Nationwide and our five national lab networks, call (877) 731-6362.

DOT-regulated alcohol testing requires federally certified urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40) and does not accept hair follicle alcohol testing for safety-sensitive roles. Hair follicle EtG testing is used mainly for non-DOT roles and other monitoring programs requiring long-term alcohol use detection. AMH Nationwide ensures all DOT testing follows the required urine protocols and directs customers accordingly. PRICING ## How much does hair follicle alcohol testing cost? The cost of hair follicle alcohol testing varies depending on the test panel selected and detection window required. Pricing can also be influenced by the specific lab network used and additional services such as MRO review. Contact AMH Nationwide at (877) 731-6362 for a personalized quote and to schedule testing.

Standard hair follicle testing analyzes approximately 1.5 inches of hair, representing about 90 days. Longer detection may require longer hair samples but is uncommon. No. Passive or environmental exposure does not produce EtG levels high enough to cause a positive hair follicle alcohol test. All non-negative test results are reviewed by a certified Medical Review Officer to ensure accurate interpretation and report findings. No. Hair follicle tests detect alcohol use over weeks to months, not recent consumption. Breath, blood, or urine tests are used for recent detection.
