Ethyl glucuronide and ethanol concentrations in femoral blood, urine and vitreous humor from 117 autopsy cases
2020
Abstract Background Vitreous humor (VH) is a specimen of great value in forensic investigations and is being used for evaluating possible post-mortem formation of ethanol. Ethyl glucuronide (EtG) is an ethanol metabolite that has found interest for the same purpose. Both compounds can be measured in VH and because of differences in rate of distribution and elimination they may offer complementary information. Methods VH, femoral blood (FB) and urine were collected from 117 autopsy cases for forensic investigation. Ethanol was measured with headspace gas chromatography, while EtG was measured with liquid chromatography – tandem mass spectrometry. Results and conclusion : Ethanol was detected in all matrices in 39 cases, while EtG was present in 62 cases. The VH-FB and the VH-urine ethanol concentrations in the 39 cases were statistically correlated (p
