All sample sets will contain two known bloodstains and two questioned stains that are pre-screened; thus, no screening data will be collected for this testing series. One of the questioned samples will contain a mixture of body fluids that includes semen. Participants may report results for STR and YSTR analyses. The known bloodstain standards are provided on cloth substrates. This test can be paired with 5801 or 5701 to meet FBI QAS test frequency requirements.

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

Samples ship in early July and data due early September.

Enrollment deadline: 15 March 2025
