Why are organs from donors sometimes rejected by the person receiving them?

Organ Transplants In order for a blood transfusion & an organ transplant to be successful, the antigens of the recipient & donor must be the same or very close.

Rejection of organ transplants occurs when the recipient's body produces antibodies in response to the antigens present in the donor's organ.

More than 50 antigens can be found in human blood. Blood Typing More than 50 antigens can be found in human blood. Of these, the most commonly tested antigens are of the ABO blood group.

blood typing in the ABO blood group is based on the presence or absence of antigens on the surface of red blood cells.

Two types of antigens are known: "A"and"B.” In addition, plasma may contain the antibodies, anti‑A and/or anti‑B.
