Sample item

Which specimen is generally important for forensic toxicology in suspected alcohol intoxication?

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

The answer and the reasoning

B. Peripheral blood

Peripheral blood is a standard specimen for quantitative toxicology because it is less prone to contamination from central redistribution than some other samples. Sampling, preservation, and chain of custody matter.

Option by option

  • A. Tear fluid only

    Tear fluid is not the routine forensic specimen.

  • B. Peripheral blood (correct)

    Correct. Peripheral blood is commonly used for ethanol measurement.

  • C. Dental plaque only

    Dental plaque has no role in ethanol quantification.

  • D. A hair clipping only

    Hair may have selected uses but is not the standard acute ethanol specimen.
