Within how many hours of a sexual assault should a sexual assault evidence kit be used for both children and adults?

The correct answer indicates that a sexual assault evidence kit should ideally be used within 72 hours of a sexual assault for both children and adults. This timeframe is critical because the sooner evidence is collected, the more likely it is to be intact and viable for analysis.

After a sexual assault, biological evidence such as bodily fluids, skin cells, and other trace evidence can degrade or be lost due to factors such as natural body processes, hygiene activities, or environmental exposure. Collecting evidence within 72 hours maximizes the chances of obtaining crucial information that can support investigations and legal proceedings.

Delays beyond this period can hinder the possibility of gathering useful evidence, although in certain circumstances, evidence can still be collected beyond 72 hours, especially if the victim is seeking medical attention or forensic care. However, the optimal window remains within 72 hours to ensure the best potential for evidence integrity and legal efficacy.
