Abstract

Hair analysis is a powerful tool for retrospective drug analysis. By determining the minor ethanol metabolites ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) in hair, even a previous consumption of alcohol is detectable. However, previous studies showed a lack of correlation if both parameters are determined simultaneously. A further study was conducted to confirm or refute these results. One hundred and sixty hair samples were analyzed for EtG and FAEE in the context of driving ability. In 109 cases, alcohol abstinence was clearly proven and was excluded in 15 cases. In 36 cases, ambiguous results were found. Possible reasons for the deviating results are discussed. It is recommended, that in context of driving ability diagnostics the EtG result is determinant. In critical cases FAEE concentrations can be determined for checking purposes, but a negative FAEE result cannot refute a determined EtG concentration >7 pg/mg.
