Phosphatidylethanol (PEth) is an ethanol-phospholipid adduct, formed via non-oxidative metabolism of ethanol. PEth was measured in femoral blood from 85 consecutive forensic autopsies and was detected in 35 of the cases at concentrations ranging from 0.8 to 22.0 μmol/l. Of the PEth positive cases, 12 did not have significant levels of ethanol in the blood. Two cases (both suicides involving hanging) had detectable ethanol, but no PEth present in the blood. We conclude that measurements of PEth provide indications of previous alcohol abuse in cases where this may not otherwise be evident.
