The Organization of Scientific Area Committees (OSAC) for Forensic Science Registry serves as a trusted repository of high-quality, technically sound standards and guidelines for the practice of forensic science. Two DNA standards that were originally drafted by OSAC’s Biological Data Interpretation and Reporting Subcommittee and published as American National Standards by the Academy Standards Board's DNA Consensus Body are currently under consideration for placement on the OSAC Registry.
When it comes to DNA evidence, detailed and comprehensive protocols are needed to ensure reliable and consistent interpretation and comparison of DNA data from single source and mixed DNA samples. Before casework data can be interpreted and compared, however, internal validation studies and appropriate laboratory-approved interpretation protocols are needed. The validation data is critical to determine a laboratory's capabilities and limitations, and provide the basis for how a laboratory developed its interpretation protocols.
OSAC has opened a thirty-day comment period to give the forensic science community an opportunity to provide specific feedback as to why the following two standards should or should not be placed on the OSAC Registry:
To consistently produce reliable, repeatable, and reproducible interpretations and conclusions that are supported by internal validation data and laboratory protocols, laboratories are encouraged to use these two documents in conjunction.
Both standards have been published by the AAFS Standards Board (ASB), and if approved, will be the first DNA standards placed on the OSAC Registry.
