Transfusion medicine, also known as blood banking, is a branch of pathology dedicated to the management of blood and blood component therapy. This includes processing, testing, and storing of blood products such as red blood cells, plasma and platelets.

A key component of transfusion medicine is ensuring compatibility between donor and recipient through blood typing, antibody screening, and crossmatching to prevent transfusion reactions.

Transfusion medicine pathologists play an important role in patient blood management, therapeutic procedures, and support for complex medical and surgical patients by maintaining rigorous safety standards and expert clinical oversight.
