Call us now at (877) 731-6362. --- The PEth Alcohol Test detects phosphatidylethanol, a blood biomarker indicating recent alcohol consumption, making it highly accurate for monitoring drinking behavior. This test is used in clinical, legal, and employment settings. AMH Nationwide routes collections through five national lab networks. Call (877) 731-6362 to arrange your PEth test. OVERVIEW ## What is the PEth Alcohol Test? The [PEth](https://amhnationwide.com/peth-testing/) Alcohol Test measures phosphatidylethanol in the blood, a direct biomarker formed only when alcohol is consumed. Unlike traditional tests detecting alcohol or its metabolites, PEth reflects drinking over the past 2 to 4 weeks, offering a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/). This test is valuable in monitoring abstinence, assessing alcohol use disorders, and supporting legal or employment decisions involving alcohol consumption. COLLECTION & PROCESSING ## How is the PEth Alcohol Test collected and processed? PEth testing requires a blood sample, collected by a healthcare professional at a designated collection site. AMH Nationwide directs test requesters 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. All non-negative PEth results undergo review by a certified Medical Review Officer as part of standard processing to ensure accuracy and proper interpretation. USE CASES ## Who orders a PEth Alcohol Test and why? The PEth test is typically ordered by healthcare providers, employers, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers, or legal representatives who require objective evidence of recent alcohol use. It supports monitoring in substance abuse treatment, compliance with court orders, workplace safety programs, and [child custody](https://amhnationwide.com/hair-follicle-drug-test-child-custody/) cases. Clinicians use it to monitor treatment progress in alcohol use disorder Employers may require it for safety-sensitive roles outside DOT regulations Legal entities use it for custody or probation compliance It is not used for DOT-regulated testing, which requires federally certified [urine](https://amhnationwide.com/urine-drug-testing/) testing TEST DETAILS ## What detection window and accuracy does the PEth test offer? The PEth test can detect alcohol consumption from approximately 2 to 4 weeks prior to sample collection. It is more sensitive and specific than urine or breath tests, which detect recent use only within hours or days. Because PEth accumulates only in the presence of ethanol, it does not produce false positives from incidental alcohol exposure. | Test Type | Detection Window | | --- | --- | | PEth Alcohol Test (Blood) | 2 to 4 weeks | | Urine Ethyl Glucuronide ([EtG](https://amhnationwide.com/hair-etg-alcohol-test/)) | 1 to 3 days | | Breath Alcohol Test | Hours | ## Schedule Your PEth Alcohol Test Today Contact AMH Nationwide at (877) 731-6362 to obtain a lab order and find your nearest collection site for PEth testing.

PEth test results are often accepted as objective evidence of alcohol use in legal settings such as custody disputes and probation monitoring, but acceptance depends on jurisdiction and case specifics. A breathalyzer measures blood alcohol concentration at the moment, detecting recent drinking within hours, while the PEth test detects alcohol use over weeks by measuring a blood biomarker. No, DOT-regulated safety-sensitive testing requires federally certified urine tests under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). PEth testing is for non-DOT roles. Results typically take several business days after the sample is collected and processed through one of the five national lab networks. No, AMH Nationwide does not offer online ordering.
