Measuring postmortem glycated hemoglobin - A comparison of three methods.

Glycated hemoglobin (HbA1c) is a glycoprotein formed as a result of the non-enzymatic addition of d-glucose to the hemoglobin β-chain. The amount of HbA1c in the blood is dependent on mean glucose levels present during the 1-2 months preceding measurement, and it is an indicator of long-term glycemic levels. HbA1c is a useful marker in postmortem biochemistry in determining cause of death in acetonemic cases by allowing to distinguish diabetic ketoacidosis (DKA) from starvation or alcoholic ketoacidosis (AKA) and intoxication by acetone or isopropanol.

Postmortem measurement of C-reactive protein and interpretation of results in ketoacidosis.

C-reactive protein (CRP) is a widely used acute phase protein that reacts to various tissue-destroying stimuli. Its forensic applications have been established in prior studies. We show that CRP can be successfully measured even after a long postmortem period, up to 18 days, which has not previously been reported.
