ETG vs PEth Alcohol Test
ETG vs PEth Alcohol Test: Choose the Right Test for Reliable Alcohol Detection
ETG vs PEth alcohol test comparison helps identify the most suitable method for alcohol detection. ETG tests detect recent alcohol use in urine up to 80 hours, while PEth tests detect alcohol consumption in blood over 2-3 weeks. Both tests are processed through national lab networks. Call (877) 731-6362 to schedule your test.
What is the difference between ETG and PEth alcohol tests?
The ETG alcohol test detects ethyl glucuronide, a metabolite of alcohol, in urine and identifies alcohol use within approximately 24 to 80 hours after drinking. The PEth alcohol test detects phosphatidylethanol in blood, a biomarker that indicates alcohol consumption over a longer period, typically 2 to 3 weeks.
ETG tests are commonly used for recent alcohol exposure monitoring, while PEth tests provide a longer detection window suitable for assessing chronic alcohol use.
How do ETG and PEth tests compare in detection windows?
ETG tests detect alcohol metabolites in urine for up to 80 hours after last use, making them effective for identifying recent drinking episodes. PEth tests detect alcohol markers in blood for up to 21 days, allowing for detection of repeated or chronic alcohol consumption.
Which alcohol test is best for different testing needs?
ETG tests are best suited for monitoring abstinence in short-term situations such as treatment programs, probation, or workplace testing requiring recent alcohol detection. PEth tests are preferred when longer-term alcohol use monitoring is necessary, such as in clinical assessments or legal cases requiring evidence of sustained drinking behavior.
How are ETG and PEth alcohol tests processed at AMH Nationwide?
AMH Nationwide routes ETG and PEth alcohol tests through five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. Each non-negative screen is reviewed by a certified Medical Review Officer as part of the standard process to ensure accuracy and compliance.
AMH provides the lab order and directs the requester to a nearby collection site. There is no option for online ordering. For DOT-regulated safety-sensitive positions, ETG testing requires the federally certified urine protocol under 49 CFR Part 40, while PEth testing is used for non-DOT roles.

What should I expect during ETG or PEth alcohol test collection?
ETG testing requires a urine specimen collected under observed or non-observed conditions depending on the program requirements. PEth testing requires a blood sample collected by a trained phlebotomist at a certified collection site. Both specimens are then sent to one of the national labs for analysis.
How much do ETG and PEth alcohol tests cost and how do I schedule?
The cost of ETG and PEth alcohol tests varies based on the testing panel and detection window required. To receive a specific quote and arrange testing through AMH Nationwide, you must call (877) 731-6362. AMH does not offer online ordering but will assist in directing you to a collection site.
Common Questions
ETG tests detect alcohol metabolites in urine for up to 80 hours after consumption, so they are effective for recent alcohol use but not for detecting use beyond about 3 days.
PEth testing detects alcohol biomarkers in blood for up to 3 weeks, making it more suitable than ETG for assessing chronic or repeated alcohol consumption over time.
DOT-regulated testing requires the federally certified urine ETG test under 49 CFR Part 40. PEth testing is not approved for DOT safety-sensitive roles.
All non-negative alcohol test results are reviewed by a certified Medical Review Officer to confirm findings and ensure accurate reporting.
No, AMH Nationwide does not allow online ordering. You must call (877) 731-6362 to have a lab order issued and be directed to a collection site.
ETG testing requires a urine sample, while PEth testing requires a blood sample collected by a trained professional at a certified collection site.
