PEth Alcohol Test (Alcohol Biomarker) (Blood)
The PEth Alcohol Test (Blood) is able to identify alcohol use in a person as far back as 3-4 weeks prior to the specimen collection. Phosphatidylethanol, or PEth, is formed in red blood cell membranes when they are exposed to alcohol. It is considered a direct biomarker for alcohol consumption.
Research has shown that use of alcohol-based hand sanitizers and mouthwashes will not affect the results of a PEth test. A confirmed positive result for PEth can be interpreted as evidence of alcohol use.
This test requires a standard blood sample that can be drawn at the Any Lab Test Now store location of your choice.
