Analytical toxicology has advanced significantly with chromatography and immunoassays, improving drug screening and biological monitoring for clinical, forensic, and industrial applications. Future needs include standardized units and simpler tests for wider laboratory use.

Area of Science:

  • Analytical Toxicology
  • Forensic Science
  • Clinical Chemistry

Background:

  • Analytical toxicology has evolved significantly since the mid-20th century with the advent of advanced spectroscopic and chromatographic techniques.
  • Current methods include thin layer chromatography, spectrophotometry, gas chromatography, high-performance liquid chromatography, and immunoassays.

Purpose of the Study:

  • To review the advancements and current scope of analytical toxicology.
  • To highlight the increasing importance of drug screening in clinical, forensic, industrial, and sports contexts.
  • To identify future needs in analytical toxicology, including standardized units and accessible testing methods.

Main Methods:

  • Review of major analytical techniques in toxicology, including chromatography (TLC, GC, HPLC) and immunoassays.

  • Discussion of applications in clinical toxicology, forensic toxicology, drug abuse screening, and industrial/environmental monitoring.
  • Analysis of current trends and future requirements for the field.

    • Main Results:

    • Gas and high-performance liquid chromatography, alongside immunoassays, are now widely employed in analytical toxicology.
    • Drug screening is crucial for patient management, pre-employment checks, and detecting illicit drug use in sports.
    • Biological monitoring for industrial exposure and environmental contaminants is increasingly valuable.

    Conclusions:

    • Analytical toxicology has seen substantial progress, with modern techniques enhancing its scope in various fields.
    • There is an ongoing need for standardized units of measurement and interpretation of results, particularly concerning behavioral effects.
    • Development of reliable, simple tests is essential for broader application in smaller laboratories.
