Immunoassays offer a simple, rapid method for detecting low molecular weight compounds in biological fluids, proving valuable in forensic science. These sensitive techniques, including radioimmunoassay and enzyme immunoassay, aid in drug screening.

Area of Science:

  • Forensic toxicology
  • Analytical chemistry
  • Immunology

Background:

  • Immunoassays can detect low molecular weight compounds lacking antigenicity.
  • Despite potential cross-reactivities, immunoassays are advantageous for biological fluid analysis due to simplicity and high throughput.
  • Immunoassays are established as sensitive analytical and screening methods in forensic sciences.

Purpose of the Study:

  • To establish and describe various immunoassay methods for detecting specific compounds in forensic science.
  • To highlight the utility of immunoassays for drug screening in biological samples.

Main Methods:

  • Development of radioimmunoassay (RIA) and enzyme immunoassay (EIA) for phenobarbital.
  • Establishment of enzyme-linked immunosorbent assays (ELISA) and latex agglutination inhibition reaction tests (LAIRT) for methamphetamine, benzoylecgonine, and morphine.

Related Experiment Videos

  • Evaluation of commercially available immunoassay kits: EMIT and Triage Biosite.

    • Main Results:

    • Established RIA and EIA for phenobarbital detection.
    • Established ELISA and LAIRT for methamphetamine, benzoylecgonine, and morphine detection.
    • Described the application of commercial kits like EMIT and Triage for drug screening.

    Conclusions:

    • Immunoassays are effective and sensitive tools for the detection of various compounds in forensic applications.
    • The established methods, alongside commercial kits, provide robust options for drug screening in biological fluids.
    • Immunoassays facilitate rapid and high-throughput analysis crucial for forensic science investigations.
