Standards for blood banks and transfusion services.

"The 33rd edition of Standards for Blood Banks and Transfusion Services details the latest standards of practice in blood banking and transfusion medicine. As in the past, each chapter heading represents one of the Quality System Essentials and the quality standards are supplemented by technical requirements. The effective date of this edition is April 1, 2022. Significant changes: In the "Preparation of Components" section (5.7.4 - 5.7.4.27), the standards have been edited to require confidence intervals for certain products where appropriate. New Standard 5.7.4.16.1 concerning components created from pathogen-reduced plasma has been added to the Standards to ensure facilities using these products are maintaining them as dictated by manufacturer's instructions. New Standards 5.7.4.23.1, 5.7.4.24.1, 5.7.4.25.1, and 5.7.4.26.1 were created to ensure that low-yield platelet products are labeled appropriately, including an accurate platelet count. Standard 5.27.1 contains a new substandard requiring the facilities define a low-titer threshold for the use of group O whole blood. A new entry to Reference Standard 5.4.1A concerning the receipt of SARS-COV2 vaccines and any associated deferrals has been added to the Standards. The content of the entry matches the requirements set forth by the FDA in September 2020 that was also included as a separate guidance released by the committee in September 2020" -- Amazon.
