Participants will report results for STR/YSTR analyses. This test can be paired with Test 5805 or 5705 to meet FBI QAS test frequency requirements.

Sample Description: Two known bloodstains and two questioned, prescreened stains. One of the questioned samples will contain a mixture of body fluids that includes semen. The known bloodstain standards are provided on FTA™ Micro Cards. Questioned stains are prescreened; thus, no screening data will be collected for this testing series.

Samples ship in March.

This test is included on CTS' Scope of Accreditation to ISO/IEC 17043.
