Toxicology Evidence Processing
The Toxicology Department is responsible for the analysis of biological fluids and tissues for the presence or absence of alcohol, drugs, and poisons. The department has a wide array of instrumentation including: Gas Chromatography/Mass Spectrometry (GC/MS), Liquid Chromatography/Tandem Mass Spectrometry (LC-MS/MS), Liquid Chromatography/Quadrupole Time of Flight (LC-QTOF), Headspace Gas Chromatography, Headspace Gas Chromatography/Mass Spectrometry, and Enzyme Linked Immunosorbent Assay (ELISA). Additionally, the toxicologists interpret their findings in respect to impairment or toxicity of the compounds detected.
The department primarily handles postmortem, driving under the influence (DUI), and criminal sexual conduct investigations. In addition, the department handles moonshine cases, investigations into potential poisonings and provides emergency analytical services for hospitals in life or death situations. Rapid preliminary analytical results are provided in cases involving child fatalities and officer involved shootings.
