The Phosphatidylethanol (PEth) Test is a highly
sensitive blood test used to detect chronic alcohol consumption. It measures
the presence of PEth, a biomarker that forms in red blood cell membranes in
response to alcohol intake. This test can provide valuable information for
medical and addiction treatment purposes. However, it is not typically used to
diagnose specific symptoms or medical conditions but rather to assess alcohol
misuse. If you have health concerns related to alcohol use, consult a healthcare
provider for proper evaluation and care.
