Clinical Significance

Ethyl Glucuronide (EtG) is a direct metabolite of ethanol, which is formed by enzymatic conjugation of ethanol with glucuronic acid. Alcohol in urine is normally detected for only a few hours, where as EtG can be detected up to several days even after complete elimination of alcohol from the body. A value that is equal to 500 ng/ml or greater is considered a positive screen result.

This test is intended for clinical monitoring and management of patients. It is not intended for non-medical use such as employment of forensic testing.
