What is forensic toxicology?

• A. The detection and identification of drugs and poisons in body fluids, tissues, and organs.
• B. The study of hair morphology.
• C. The analysis of fiber traces.
• D. The evaluation of blood spatter.

Answer: (A)

Forensic toxicology focuses on detecting and identifying drugs, poisons, and other toxic substances in the body to determine exposure, impairment, or poisoning in a legal context. It involves analyzing specimen types such as blood, urine, vitreous humor, liver, or brain to establish presence and concentration, which helps interpret effects and possible contributions to a crime or death. The process usually starts with screening tests to flag potential positives, followed by confirmatory methods like gas chromatography–mass spectrometry or liquid chromatography–tandem mass spectrometry for definitive identification and precise quantification. Interpreting results also requires considering factors like pharmacokinetics, postmortem changes, and mixtures of substances. The other options describe different forensic specialties—hair morphology, fiber trace analysis, and bloodstain pattern analysis—none of which focus on detecting or identifying toxic substances.
