Donated BloodFacilities providing Transfusion Services must follow applicable FDA regulations. The AABB Standards for Blood Banks and Transfusion Services provide requirements not only for those accredited by AABB, but also for those facilities required by state law to follow the Standards. They provide excellent guidelines for all other facilities, and are referenced extensively in the College of American Pathologists’ Transfusion Medicine accreditation checklist. This section provides information based on the Standards, regulatory requirements and United Blood Services’ practices relating to transfusion and post-transfusion activities.
