Understanding PEth: A Reliable Marker for Alcohol Consumption
What is PEth?
Phosphatidylethanol (PEth) is a unique phospholipid that forms in the presence of ethanol (alcohol) within the human body. Unlike other substances that may naturally occur or fluctuate due to non-alcohol-related factors, PEth is exclusively created when alcohol interacts with cell membranes. This specificity makes it a powerful biomarker for detecting and quantifying alcohol use.
