For cases that are not related to DUI/D, the type of evidence that should be collected will depend on how much time has elapsed between the event and the sample collection. If the event (e.g., sexual assault) occurred within the last 12 hours, collect blood. If the event occurred more than 12 hours ago, collect blood and urine. Drugs may be detectable in urine for longer than in blood, but urine results generally cannot be used as evidence of drug impairment, merely drug use.
DFS Toxicology will only accept human body fluids and tissues for analysis. Examples of items that are not accepted include, but are not limited to:
Contaminated bed sheets
Contaminated baby bottle contents (may be accepted for potential alcohol contamination)
