Value of Ethyl Glucuronide in Plasma as a Biomarker for Recent Alcohol Consumption in the Emergency Room

Abstract

EtG testing in blood was found useful in the ED as a way to detect recent drinking, even in cases of a negative ethanol test, and to confirm abstinence from alcohol. This sensitive and specific short-term biomarker provides valuable additional information about individual drinking habits and might also be helpful to identify an alcohol hangover.
