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 (approximately 0.02%) of any ethanol in the bloodstream is conjugated in the liver with glucuronic acid to form ethyl glucuronide. This compound is excreted in the urine. The applications of EtG as a marker of ethanol ingestion have been extensively described in peer-reviewed scientific literature.
