Forensic toxicologists analyze a variety of biological samples to detect and quantify toxic substances. Common samples include:
Blood: Often used because of its ability to reflect recent exposure to toxins. Urine: Commonly tested in drug screening due to its non-invasive collection and longer detection window for certain substances. Hair: Provides a longer history of substance use, as many toxins accumulate in hair over time. Tissues and Organs: Examined in post-mortem cases to provide a comprehensive understanding of substance distribution in the body.
