The type of transfusion reaction that occurs due to the destruction of incompatible red blood cells is hemolytic. This reaction is primarily due to the recipient's immune system recognizing the transfused red blood cells as foreign, which leads to an immune response that destroys those cells.

Hemolytic reactions can happen when a person receives blood with incompatible ABO or Rh antigens. The immediate response involves antibodies binding to the foreign red blood cells, leading to their lysis (destruction). This can result in symptoms such as fever, chills, back pain, and hemoglobinuria.

In contrast, circulatory overload occurs when there is too much blood transfused too quickly, leading to fluid overload in the vascular system rather than an immune reaction. Febrile reactions are associated with the recipient's immune response to white blood cells or plasma proteins in the transfused blood but do not involve the destruction of red blood cells. Anaphylactic reactions are severe allergic responses that can occur due to proteins in the blood products but are unrelated to the incompatibility of red blood cells.
