Abstract

Highlights: Several studies report a relationship between PMI and vitreous solute concentration. To date, these expressions have not utilised data for when PMI = 0. Calibration against the antemortem vitreous concentrations may improve accuracy. We have reported the antemortem vitreous concentrations of 15 analytes, including potassium. Abstract: The purpose of this letter is to highlight that postmortem interval estimates using vitreous potassium concentrations may be further optimised by calibration against antemortem vitreous samples.
