WebEthyl glucuronide (EtG) is a minor metabolite of ethanol and is formed from ethanol by conjugation with uridine diphosphate (UDP)-glucuronic acid. EtG has been detected in human urine, serum and clipped hair samples of ethanol consumers. The formation of EtG depends on the serum ethanol concentration. WebIn this group the maximum of serum ethyl glucuronide concentration (SEtGC) and of serum ethanol concentration (SEC) did not exceed 3.7 mg/L and 1.5 g/L respectively. EtG peaked 2 to 3.5 h later than ethanol. EtG was eliminated with a terminal half-life of 2 to 3 h. EtG decreased slower than ethanol—the metabolite could still be determined in ...
