DNA - Sample Specific Tests

Our DNA Sample Specific series contains six individual tests. Each test is issued once per year and allows nine weeks (from shipment to data due date) for examination. All sample sets will contain two known bloodstains and two questioned stains that are pre-screened; thus, no screening data is collected for this testing series. The known bloodstain samples are dried on either FTA Micro Cards or cloth substrates, and participants may report results for STR and YSTR analyses. We structure these tests to assist laboratories in meeting the FBI QAS test frequency requirements; this series and the Forensic Biology series are scheduled so that participants can choose tests from either series and remain in compliance with those requirements.
