Summary
Ethyl glucuronide (EtG) is a reliable biomarker for detecting alcohol consumption, even after ethanol has cleared the body. This review covers EtG
Area of Science:
- Toxicology
- Biochemistry
- Clinical Chemistry
Background:
- Ethyl glucuronide (EtG) is a stable metabolite of ethanol, detectable in various biological samples long after alcohol elimination.
- EtG bridges the detection gap between short-term alcohol markers (ethanol) and long-term alcohol misuse markers (GGT, MCV, CDT).
Purpose of the Study:
- To review analytical techniques for EtG detection.
- To discuss the clinical applications of EtG testing.
- To identify outstanding questions regarding EtG's use.
Main Methods:
- Review of analytical methodologies for EtG detection in biological matrices.
- Analysis of clinical utility and interpretation of EtG results.
Main Results:
- EtG offers a specific detection window for alcohol consumption.
- High sensitivity and specificity make EtG a valuable marker.
- EtG aids in monitoring alcohol use and relapse prevention.
Conclusions:
- EtG is a promising biomarker for assessing alcohol consumption and supporting relapse control.
- Further research is needed to address remaining questions on its clinical implementation.
