How to Interpret Hair EtG Concentrations in Individuals with High Body Mass Index? Brief Commentary on: Influence of Body Mass Index on Hair Ethyl Glucuronide Concentrations

Body mass index (BMI) is a variable that complicates the interpretation of the alcohol metabolite ethyl glucuronide (EtG) in hair. However, direction on how EtG should currently be interpreted within individuals consuming moderate and excessive daily amounts of alcohol related to their BMI is lacking. In light of interpretation of EtG in individuals with high BMI, we present post hoc analysis of earlier data regarding the effect of BMI on hair EtG concentrations.
