What causes a blood transfusion reaction? Transfusion reactions include urticaria, fevers, and hemolysis caused by antibodies in the recipient directed against components of the transfused product, including antigens on the red blood cells (RBCs) themselves, plasma proteins, or antigens on contaminating white blood cells or platelets. A delayed hemolytic transfusion reaction usually does not manifest as dramatically as acute hemolytic transfusion reaction. Allergic Reactions Blood Transfusion Reactions Rarely, severe symptoms occur. If the recipient's immune system attacks the red blood cells of the donor, it is called a hemolytic reaction. Delayed hemolytic transfusion reactions (DHTR) are caused by an anamnestic antibody response in the recipient precipitated by re-exposure to a non-ABO red cell antigen previously introduced by transfusion, transplantation or pregnancy. Some of the most common causes include: Transfusion carried out too quickly Improper storing of blood Using contaminated blood Mismatched blood type Using blood from an infected donor Treatments For Blood Transfusion Reactions In Cats that can cause transfusion reactions.
