The [PEth](https://amhnationwide.com/peth-testing/) Alcohol Test for DUI Monitoring is a blood test designed to detect the presence of phosphatidylethanol (PEth), a direct biomarker of alcohol consumption. Unlike breath or [urine](https://amhnationwide.com/urine-drug-testing/) tests, the PEth test can detect alcohol use over a longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/), up to three weeks. Courts and legal authorities commonly use this test for monitoring individuals with DUI charges to ensure compliance with sobriety requirements. LAB AND COLLECTION ## How is the PEth test for DUI alcohol monitoring collected and processed? PEth alcohol testing requires a blood sample collected at a certified location. AMH Nationwide facilitates the lab order and directs the requester 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. There is no online ordering; all collections are routed through these labs to maintain chain of custody and accuracy. Every non-negative PEth test result is reviewed by a certified Medical Review Officer as part of standard processing to ensure proper interpretation and reporting.
