In toxicology, various types of samples are collected based on the nature of the investigation:
Blood: Often used for detecting recent exposure to toxins, as well as for measuring the concentration of toxins in the bloodstream. Urine: Commonly collected for drug testing and monitoring long-term exposure to toxins. Tissues: Useful in postmortem examinations to identify systemic distribution of toxins. Hair: Provides a timeline of exposure to toxins over weeks to months. Environmental samples: Such as soil, water, and air are collected for environmental toxicology studies.
