Our Toxicologists combine their expertise in chemical analysis with knowledge of drug pharmacology, metabolism and pharmacokinetics, to interpret the significance of any substance found.  The analytical results allow medical examiners to determine the cause and manner of deaths, and also assist in the investigation of drug and/or alcohol-related crimes.
