Ethyl Glucuronide/Ethyl Sulfate Alcohol Metabolite Analysis EtG/EtS

Ethyl glucuronide (EtG) is a minor metabolite of ethanol (ethyl alcohol). It is formed in vivo as a consequence of alcohol exposure. A small fraction (0.02%) of a dose of alcohol is conjugated in the liver with glucuronic acid to form ethyl glucuronide, or with sulfuric esters to form ethyl sulfate. These compounds are excreted in the urine.

Ethyl sulfate (EtS) is also a direct metabolite of ethanol similar to EtG. EtG, but not EtS, is sensitive to bacterial hydrolysis. Levels of ß-glucuronidase increase in urinary tract infections, kidney disease and bladder cancer. Elevated levels of this enzyme may result in the breakdown of ethyl glucuronide and a possible negative EtG result following alcohol consumption, but EtS is stable and eliminates this problem.

EtG and EtS can be detected in urine for 3 to 5 days after heavy alcohol use. A positive finding of EtG and EtS in urine provides strong evidence that the person recently been exposed to alcohol, even if the alcohol itself is no longer detectable. Therefore, these compounds are regarded as a biomarkers of alcohol exposure and, potentially, relapses of alcohol use by an individual who is under restriction.

Forensic Laboratories was one of the first laboratories to test for EtG and EtS in urine, and was the first to test for EtG & EtS in oral fluid.
