LOP Enrollment Deadline: 2 January 2026

This test is still open for enrollment via credit card only. Please select credit card as the payment method during the checkout process if your order includes any Late Order Purchase (LOP) tests.

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.
