Blood group O is considered to be the universal donor. People with blood group O can donate to any other blood type. Blood group AB is called a universal recipient because it can receive an organ or blood from people with any type of blood. The table below shows which blood type you can donate to which blood group.
Being a compatible blood group is only part of knowing if a person will be compatible. You can donate your organs even if you don't belong to a compatible blood group. The Rh factor is not important for kidney compatibility. Ideally, blood types should be compatible.
This is quite complicated, but in general, a person who has the blood type O can donate to anyone; Or it is a universal donor. However, a person with blood group A can only donate to someone with blood group A, blood group B to B, and AB to AB. As for the recipient, a person with blood group O can only receive one kidney O, however, a person with blood type A can receive kidney A or O and a person with blood type B can receive kidney B or O. The recipient's body will always see an organ as a foreign object.
If a deceased donor and a transplant recipient do not share the same blood type, a transplant will not be performed. When a living donor and a transplant recipient do not share the same blood type, the recipient may undergo special treatment to calm the immune system and allow the recipient to accept the kidney that is incompatible with the living donor's blood group. Without this treatment, the recipient's body will reject the new kidney, resulting in failure of the transplant. Usually, the recipient or his family will approach the donor and ask if he or she would be prepared to donate a kidney.
It is obvious that an increase in post-mortem organ donation rates would positively affect patients of all blood groups who were on the waiting list and not just for kidney transplantation.
