The usefulness of point-of-care (POC) tests in screening elevated glucose and ketone body levels postmortem.

The aim was to evaluate the performance of point-of-care (POC) tests in detecting glucose and ketone bodies in postmortem (PM) samples and to assess the usefulness of POC tests in sample screening for more precise analyses. Glucose and ketone body, β-hydroxybutyrate (BHB), were measured from vitreous humor (VH) in 52 autopsy cases with a POC blood glucose monitoring device (BGMD). In addition glucose and ketone bodies, acetone (Ac) and acetoacetate (AcAc), were measured from urine samples in another set of 59 cases with semi-quantitative stick tests.

Renal markers cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) in postmortem samples.

Purpose: Renal markers may provide valuable information for cause of death (CoD) investigation when assessing the influence of impaired kidney function. A commonly used marker, creatinine (Cr), increases due to kidney injury and is known to be reasonably stable in postmortem (PM) samples. More sensitive markers are needed, as the increase of serum Cr level only occurs after relatively severe renal damage.
