Performing Laboratory
NorDx Laboratories
Useful For
A screening assay to detect Ethyl Glucuronide in urine.
If the Ethyl Glucuronide screen is ≥ 500 ng/mL, the Ethyl Glucuronide confirmation/quantitation by LC-MC/MS is performed at an additional charge.

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.
Maximum Laboratory Time
