Postmortem biochemical investigations in hypothermia fatalities.

Despite the progress made during the past several decades in forensic pathology, the possibilities for the postmortem diagnosis of hypothermia remains relatively limited. Aside from histology and immunohistochemistry, numerous authors have investigated the postmortem biochemistry of hypothermia fatalities. Several biochemical markers (e.g., glucose, electrolytes, hormones, ketone bodies, and neurotransmitters) and various biological samples (e.g., blood, urine, heart, liver, skeletal muscle as well as pericardial and cerebrospinal fluids) have been proposed as potentially useful markers to improve the insufficient diagnostic efficacy of macroscopic and microscopic findings. The aim of this article is to review the medicolegal literature covering the postmortem biochemical investigations that are associated with hypothermia cases as well as report our own research results on this topic where possible.
