Sample item

Why should postmortem toxicology results be interpreted with caution?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Redistribution and decomposition can change measured concentrations

Postmortem redistribution, sample site, decomposition, and treatment history can alter concentrations, so results require expert correlation with circumstances and pathology.

Option by option

  • A. All drugs disappear immediately after death

    Many drugs remain detectable after death.

  • B. Redistribution and decomposition can change measured concentrations (correct)

    Correct: death-related changes can distort measured drug levels.

  • C. Blood samples always equal living therapeutic levels

    Postmortem and living concentrations are not directly interchangeable.

  • D. Toxicology never helps determine cause of death

    Toxicology can be highly informative when contextualized.
