Forensic Toxicology

Forensic ToxicologyThe Forensic Toxicology Section serves the law enforcement, medical examiner, coroner, and court systems of the state of Arkansas in three primary ways:

  1. Death Investigations 
     Biological samples are analyzed for the presence of drugs and toxins, which can help elucidate the cause and manner of death in cases where these substances play a role.
  2. Criminal Investigations 
     Biological samples are analyzed for the presence of drugs and toxins that may be important in criminal cases such as DUI, DWI, drug-facilitated sexual assault, and many other types of criminal offenses.
  3. Court Testimony 
     The Toxicologists testify in municipal, circuit, and federal court as needed regarding the results and implications of our findings.

Testing

The Forensic Toxicology Section uses a variety of capable and current methods and instrumentation to ensure that our results are accurate, reliable, and timely. Among these are:

  • Gas chromatography-mass spectrometry (GC-MS),
  • Tandem liquid chromatography-mass spectrometry (LC-MS-MS),
  • Headspace gas chromatography,
  • UV-visible spectroscopy, enzyme-linked immunosorbent assay (ELISA), and
  • Enzyme multiplied immunoassay technique (EMIT)

Forensic Toxicology TestingThe analysis performed in an individual case can range from blood alcohol testing to a full determination of the presence and concentration of multiple drugs. The tests that are performed depend upon the needs of the case and the samples we receive.
