In forensic toxicology, which specimens are commonly analyzed?

• A. Blood and urine only.
• B. Hair and nails only.
• C. Saliva and sweat only.
• D. Body fluids, tissues, and organs.

Answer: (D)

Specimen diversity is essential in forensic toxicology because drugs and poisons can be present in many parts of the body, and the choice of specimen depends on the situation, such as time since exposure, whether the case is antemortem or postmortem, and sample stability. The broadest and most applicable category is body fluids, tissues, and organs, since this covers the range of matrices labs routinely analyze to detect and quantify substances. Blood and urine are common primary specimens, but toxicologists also work with other fluids like saliva and vitreous humor, as well as tissues and organs such as the liver and brain, to obtain a complete picture. The other options point to narrower subsets and don’t reflect the variety of specimens frequently encountered in practice.
