Phosphatidylethanols PEth are a group of phospholipids formed only in the presence of ethanol via the action of phospholipase D PLD. Chemically, phosphatidylethanols are phospholipids carrying two fatty acid chains , which are variable in structure, and one phosphate ethyl ester. When ethanol is present, PLD substitutes ethanol for water and covalently attaching the alcohol as the head group of the phospholipid; hence the name phosphatidylethanol. Normally PLD incorporates water to generate phosphatidic acid PA ; the process is termed transphosphatidylation. The lipid accumulates in the human body and competes at agonists sites of lipid-gated ion channels contributing to alcohol intoxication. Levels of phosphatidylethanols in blood are used as markers of previous alcohol consumption.

Answers From the Lab. Several major medical organizations recommend routine screening for unhealthy alcohol use. This blood test has a much longer window of detection than existing urine tests for alcohol use. Jannetto says. The preferred screening approach for ethanol — the chemical term for alcohol — measures certain substances that the body produces when ethanol is metabolized. The direct ethanol metabolites i. The window can be longer in individuals who chronically or excessively consume alcohol," Dr. Listen to learn more about how PETH provides enhanced screening for alcohol consumption.

In most studies, the alcohol marker phosphatidylethanol PEth was used to differentiate social drinking from alcohol abuse. This study investigates PEth's potential in abstinence monitoring by performing a drinking study to assess the detection window of PEth after ingesting a defined amount of alcohol. In the week after drinking, blood and urine samples were taken daily; in the second week, samples were taken every other day. Ethyl glucuronide and ethyl sulfate were determined in urine for abstinence monitoring. Positive PEth values resulted from drinking events prior to this abstinence period.

Federal government websites often end in. The site is secure. The present paper aims at a systematic review of the current knowledge on phosphatidylethanol PEth in blood as a direct marker of chronic alcohol use and abuse. The present analysis demonstrates a good clinical efficiency of PEth for detecting chronic heavy drinking. Alcohol abuse and dependence are globally prevalent disorders, which span various socio-demographic groups and produce a broad range of secondary injuries and diseases [ 1 , 2 ]. Objective clinical and biochemical tests for characterizing the drinking pattern, quantifying the amount of daily ingested ethanol, and efficiently detecting alcohol-induced disorders are critically needed in both treatment and research areas [ 3 , 4 ]. Guidance on the investigation of suspected alcohol dependence or abuse includes symptoms, medical history, self-report forms, special questionnaires, clinical examination and biochemical investigations. These approaches exhibit, however, limitations in the forensic setting, where individuals are motivated to deny or minimize the magnitude of their drinking behavior in order to mitigate the professional and legal ramifications of alcohol abuse [ 7 , 8 ].
