Transfusion medicine (or transfusiology) is the branch of medicine that is concerned with transfusion of blood and blood components. It encompasses issues of blood donation, immunohematology and other laboratory testing, transfusion practices, patient blood management, therapeutic apheresis, stem cell collections, cellular therapy, and coagulation. Laboratory management and understanding of state and federal regulations related to blood products are also a large part of the field.
Transfusion Medicine is usually a branch of clinical pathology.
The blood donor center is the facility that collects and processes blood products. The blood bank is the section of the clinical laboratory where clinical laboratory scientists process and distribute blood products. Both areas are typically overseen by either a general pathologist or a specialist in Transfusion Medicine.
