Abstract:
Infectious disease constitutes on one of the main causes of death that is identified on forensic autopsies. However, the postmortem diagnosis of these diseases and the assessment of their severity constitute major challenges. Procalcitonin (PCT), which is used as a biomarker for sepsis in clinical settings, has been applied in the context of forensic autopsies. In this study, we aimed to evaluate the utility of PCT testing in the postmortem diagnosis of infectious disease. This retrospective analysis included cases wherein autopsies with PCT testing were performed at the National Forensic Service between November 2023 and December 2024. Relevant data were collected through a comprehensive review of autopsy reports. Although the PCT concentrations in the infectious disease group were significantly higher than those in the control group, clinical sepsis criteria showed limited sensitivity in the postmortem diagnosis of infectious diseases. The comparison of clinical medical records and postmortem laboratory results revealed that PCT concentrations decreased after death. Thus, despite the usefulness of PCT testing for the postmortem diagnosis and determination of death from infectious diseases, the results should be interpreted comprehensively in conjunction with other autopsy findings rather than being used as a standalone criterion.
