The BCA Toxicology section utilizes immunoassay and mass spectrometry to analyze antemortem and postmortem biological samples for illicit drugs and prescription medications. Forensic drug testing is a viable investigation tool in cases ranging from DWI to Homicide.
The Toxicology section currently uses the following instrumentation to look for drugs:
- Enzyme Immunosorbent Assay (EIA) - Blood screening for all confirmable drugs (exception: Bath Salts and Fentanyls which are tested upon request in blood samples)
- 3200 QTRAP Mass Spectrometer (QTRAP) - Urine screening for all confirmable drugs
- 4500 QTRAP Mass Spectrometer (QTRAP) - Urine screening for all confirmable drugs (includes THC and Synthetic Cannabinoids)
- Gas Chromatograph Mass Spectrometer (GC-MS) - Used to confirm drugs in blood and urine
- Liquid Chromatograph Mass Spectrometer (LC-MS/MS) - Used to confirm drugs in blood and urine
Drugs that are identified in blood samples are reported quantitatively (amount) while drugs that are identified in urine are reported qualitatively (present or not detected).
Drugs can be identified in blood
unless specifically stated otherwise.
