It is important for both surgeries to be scheduled for the same time in case either donor changes their mind at the time of surgery. Each donor gives a kidney to the other person's intended recipient.īoth donors and candidates are carefully evaluated and tested medically and psychologically to assure that the benefits outweigh the risks. This allows two transplant candidates to receive organs and two donors to give organs though the original recipient/donor pairs were unable to do so with each other.įigure 1: In paired exchange, an incompatible donor/ recipient pair (such as a mother and son that don't have compatible blood types) are matched with another incompatible donor/recipient pair for a "swap". If the recipient from one pair is compatible with the donor from the other pair, and vice versa– the transplant center may arrange for a "swap"–for two simultaneous transplants to take place. Paired exchange involves two living donors and two recipients. Paired exchange programs allow you to get a kidney from another donor who is not a match for their intended recipient. However, the donor may consider donating through a paired exchange program. If blood types are not compatible, the donor will not be able to donate directly to you. Recipients with blood type AB… can receive a kidney from blood types A, B, AB and O (AB is the universal recipient: recipients with AB blood are compatible with any other blood type).Recipients with blood type B… can receive a kidney from blood types B and O.Recipients with blood type A… can receive a kidney from blood types A and O.Recipients with blood type O… can receive a kidney from blood type O only.Donors with blood type O… can donate to recipients with blood types A, B, AB and O (O is the universal donor: donors with O blood are compatible with any other blood type).Donors with blood type AB… can donate to recipients with blood type AB only.Donors with blood type B… can donate to recipients with blood types B and AB.Donors with blood type A… can donate to recipients with blood types A and AB.The following blood types are compatible: The Rh factor (+ or -) of blood does not matter in a transplant. Kidney donors must have a compatible blood type with the recipient. If the donor's blood type works with your blood type, the donor will take the next blood test (tissue typing). Blood typing is the first blood test that will determine if your blood is compatible with the potential donor's blood.
