Clinical Significance

Drug Monitoring, Phosphatidylethanol (PEth), Blood - Alcohol abuse remains a significant public health challenge in the United States. As a long-term, specific and direct biomarker of alcohol consumption, Phosphatidylethanol (PEth) is a group of phospholipids formed in the presence of ethanol and incorporated into the phospholipid membrane of red blood cells. PEth detection is suggestive of ethanol ingestion over multiple days. PEth is detectable for 1-2 weeks. The predominant PEth homologues are PEth 16:0/18:1 (POPEth) and PEth 16:0/18:2 (PLPEth), which account for 37-46% and 26-28% of the total PEth homologues, respectively.
