AABB Releases 35th Edition of BB/TS Standards

March 02, 2026

The 35th edition of AABB’s Standards for Blood Banks and Transfusion Services (BB/TS Standards) is now available in the AABB Store.

The 35th edition clarifies requirements for notifying AABB of accreditation-relevant changes and refines expectations for equipment investigations following nonconformances. The standards also establish monitoring requirements for critical technology infrastructure and add a new standard requiring preparation of pathogen-reduced cryoprecipitated fibrinogen complex in accordance with manufacturer instructions.

AABB’s BB/TS Standards Committee released a document that outlines significant changes to the 35th edition and the committee’s responses to public comments.

The standards take effect April 1 and are available in electronic and print formats or as a bundle of both versions. AABB also offers a print bundle that includes the standards and the Guidance for Standards for Blood Banks and Transfusion Services.

Organizations interested in adopting the standards can participate in a complimentary two-week trial of the electronic version in the Standards Portal.
