Postmortem Toxicology


Postmortem toxicology supports the medical examiner and coroner communities in medicolegal death investigations by helping to identify drugs or other toxic substances where drugs may be relevant to the death investigation.

Postmortem toxicology demands high-quality testing performed by skilled laboratory analysts. ChemaTox’s testing procedures satisfy the most rigorous requirements of laboratory analysis, thus meeting the high standards required to qualify as evidence in courts of law.
