Study Notes
ABO Antigens and Blood Transfusion
- ABO antigens are important because they can trigger an immune response, leading to rejection of a transplanted organ or blood transfusion reaction.
- It is necessary to check ABO blood type before transplantation to ensure compatibility between the donor and recipient, preventing an adverse immune response.
- ABO blood type matching is not necessary in the case of bone marrow transplantation, as the recipient's immune system is suppressed, and the donor's bone marrow cells will not trigger an immune response.
