Part 1271 regulates your specimens as HCT/Ps and drives much of your recordkeeping. We build systems that support Subpart C donor-eligibility determinations, capturing screening and infectious-disease testing in access-controlled, audit-logged records. For Subpart D good tissue practice, we make sure specimen tracking lets you trace any vial back to its donor and forward to its recipient. Retention is enforced so records survive at least ten years past a specimen’s distribution or disposition, whichever is later. We also coordinate with your CLIA lab systems and quality team so the documentation holds up under FDA inspection.
