Anti-ABO Antibodies

Anti-ABO antibodies are proteins produced by the immune system in response to the presence of blood group antigens (A or B) that are not found in a person's own blood type. For instance, if someone with blood type A receives blood from a type B donor, their body will recognize the B antigens as foreign and create anti-B antibodies to attack them. This immune response can lead to serious complications. Understanding anti-ABO antibodies is crucial in blood transfusions and organ transplants to prevent adverse reactions and ensure compatibility between donors and recipients.
