Ethyl glucuronide is widely used as a biomarker for detecting alcohol consumption in various fields. In forensic science, it helps determine recent alcohol intake, even after ethanol is no longer detectable in the body, making it valuable in legal cases or workplace testing. In healthcare, it assists in monitoring patients undergoing alcohol rehabilitation or those with conditions requiring abstinence, such as liver disease. Additionally, it is used in clinical research to study alcohol metabolism and its effects on the body. Its stability in urine and hair makes it a reliable tool for long-term alcohol use assessment.
