What are best practices for handling sexual assault kits, storage, and submission for analysis?

• A. Submit to any lab regardless of accreditation.
• B. Delay submission for extended periods.
• C. Proper collection with sterile technique; proper packaging; chain-of-custody logs; timely submission to accredited labs; proper preservation.
• D. Collect and store without documentation.

Answer: (C)

Handling a sexual assault kit properly means protecting the evidence from collection through submission. Start with sterile collection and technique to prevent contamination and ensure the sample truly represents what occurred. Using sterile tools and following sequence protocols helps maintain the integrity of any DNA or trace evidence.

Next, make sure the kit is packaged correctly. Use appropriate containers, seal them properly, and label everything with the case number, date, time, and the staff member’s initials. Proper packaging protects the samples from moisture, cross-contamination, and physical damage, which could compromise results.

Maintain a meticulous chain of custody. Log every movement or transfer of the kit with dates, times, and the identity of each person who handles it. This documentation demonstrates that the evidence has remained under control and unaltered, which is essential for admissibility in court and for maintaining trust in the results.

Submit the kit promptly to an accredited forensic laboratory. Accredited labs meet quality standards for testing, reporting, and admissibility. Timely submission helps preserve the integrity of the evidence and may affect the viability of certain analyses.

Preserve the evidence properly during storage. Keep it in the specified conditions (temperature, humidity, and protection from sunlight as required) and avoid unnecessary handling. Proper preservation reduces degradation and makes re-testing or re-analysis possible if needed.

Together, these practices maximize the reliability of analysis, support ongoing investigations, and help ensure that the evidence can be used effectively in legal proceedings.
