The Forensic Toxicology Laboratory determines the presence of alcohol, drugs, and other substances by analyzing blood, urine, and vitreous fluid. Medical Examiners use toxicology results to determine the cause and manner of death. Law Enforcement agencies use toxicology results to determine the presence of alcohol or drugs in cases involving driving under the influence (DUI), automobile homicides, sexual assaults, and other crimes.
Toxicology staff conduct analyses, issue reports on their findings, and provide courtroom testimony to interpret test results for the public.
The mission of the Utah Forensic Toxicology Laboratory is to provide excellence in toxicological analysis through the application of current forensic techniques and ongoing innovation to the statewide criminal justice community and the medical examiner's office.


The ability to detect and confirm for different drug classes/types is ever evolving for Forensic Toxicology. Please refer to the Client Services Manual for the current list of drugs that may be tested. Samples may be sent to a drug-reference laboratory if a suspected drug is not listed in our testing panel.
