Study Notes
Specimen Collection for Drug Analysis in Death Investigations
- Blood: Used to assess the relationship between a drug and a suspected cause of death.
- Urine: Demonstrates drug use but not necessarily the cause of death.
- Gastric contents: Assesses recent drug ingestion or as a factor in sudden death.
- Vitreous humor: (eye fluid) is used to measure drug concentrations when other body fluids are unavailable (e.g., due to decomposition).
- Bile: Evaluates substances that concentrate in bile.
- Hair: Useful for evaluating chronic drug exposure; segmenting allows for dating the exposure.
