Urine Alcohol Screen (EtG)

 

Alcohol is rapidly eliminated from the body at a rate of approximately one drink per hour. 

 

Ethyl glucuronide (EtG) can be detected in the blood for up to 36 hours and in the urine for up to 5 days after heavy alcohol use. A positive finding of EtG in urine of an individual provides strong evidence that the person recently consumed alcohol, even if the alcohol itself is no longer detectable. Therefore, this compound is regarded as a biomarker of alcohol consumption and, potentially, relapses of alcohol use by an individual who is under restriction.
