What is the minimum pretransfusion testing requirement for autologous donations collected and transfused by the same facility?

For autologous donations where the blood is collected and transfused within the same facility, the minimum pretransfusion testing requirement is ABO and Rh typing only. This is because autologous transfusions involve the patient receiving their own blood, which significantly reduces the risk of transfusion reactions that can occur with donor blood.

Since the blood is sourced from the same individual, the primary concern is to ensure that the blood type is correctly identified to prevent any mismatch during transfusion. The ABO and Rh typing ensures that the proper components are being returned to the patient in accordance with their blood type.

Antibody screening and crossmatching are typically more relevant in allogeneic (donor) transfusions, where the compatibility between a donor and a recipient must be confirmed due to the potential for immune reactions. However, in the case of autologous donations, the inherent risk is greatly minimized, allowing for the simpler requirement of just ABO/Rh typing.

This understanding reflects the streamlined approach to patient safety in autologous transfusions, where the need for extensive compatibility testing is not as critical given that the blood comes from the same individual.
