Ethyl glucuronide (EtG) is a metabolite of ethanol which is formed in the body by glucuronidation following exposure to ethanol, usually from drinking alcoholic beverages.It is used as a biomarker to test for ethanol use and to monitor alcohol abstinence in situations where drinking is prohibited, such as by the military, in alcohol treatment programs, in professional monitoring programs ...
[4] [6] Alcohol dehydrogenase and aldehyde dehydrogenase are present at their highest concentrations (in liver mitochondria). [98] [107] But these enzymes are widely expressed throughout the body, such as in the stomach and small intestine. [2] Some alcohol undergoes a first pass of metabolism in these areas, before it ever enters the ...
After cessation of alcohol intake, the half-life of PEth is between 4.5 and 10 days in the first week and between 5 and 12 days in the second week. [2] As a blood marker PEth is more sensitive than carbohydrate deficient transferrin (CDT), urinary ethyl glucuronide (EtG) and ethyl sulfate (EtS). [8]
The ethanol conjugates called ethyl glucuronide and ethyl sulfate remain detectable for up to three days after ethanol consumption and are quite useful for detection of occult/denied alcohol use disorder. Both these substances are detectable clinically through urine drug testing by commercial toxicology labs.
Ethyl glucuronide and ethyl sulfate are excreted in urine as metabolites of ethanol and are used to monitor alcohol use. [8] Glucuronic acid and gluconic acid are fermentation products in Kombucha tea. [9] Glucuronic acid is a precursor of ascorbic acid (vitamin C, formerly called L-hexuronic acid). Ascorbate can be biosynthesized by higher ...
In the detection of ethyl glucuronide, or EtG, testing can detect amounts in picograms (one picogram equals 0.001 nanograms). However, there is one major difference between most drugs and alcohol metabolites in the way in which they enter into the hair: on the one hand like other drugs FAEEs enter into the hair via the keratinocytes , the cells ...

In 2013, Psychemedics Corporation began offering hair based alcohol Ethyl glucuronide testing. This testing was previously attempted by laboratories in the United Kingdom, but has suffered from numerous lawsuits.
