Phosphatidylethanol (PEth)

Phosphatidylethanol is a direct biomarker for managing the consumption of alcohol. Phosphatidylethanol is only produced by the body on intake of ethanol or alcohol. PEth can be found in the bloodstream for up to two weeks. PEth is most likely used as an indicator of chronic alcohol abuse. PEth is a reliable marker for detecting alcohol as it has high sensitivity.

Additional Information

The PEth blood test is a relatively new test, and it is not yet clear how accurate it is. However, it may be useful for detecting alcohol consumption in people who are trying to stay sober or who are involved in a court case where alcohol consumption is an issue.

The PEth blood test is a simple and relatively inexpensive test that can be used to help determine if someone has been drinking alcohol. It is important to note, however, that the PEth blood test is not always accurate, and further research is needed to determine its usefulness.
