Biomarker profile

  • Alcohol Consumption

Alcohol Consumption (1 Biomarker)

Phosphatidylethanol in blood (PEth) is a stable, highly specific and sensitive marker for detecting chronic excessive drinking behaviour with a regular daily alcohol intake. PEth is found to be detectable in blood up to 28 days without alcohol. Sex, age, gender and body mass do not influence the normalisation rate of PEth. In comparison to serum CDT, PEth appears more sensitive. CDT is an indirect marker, PEth is a direct marker.
