Perfect match transplants have the best chance of working for many years. These harmful substances have proteins called antigens coating their surfaces. The final step in determining compatibility is "crossmatching" : live cells from the donor, and fresh antibodies sample from the blood of the recipient are mixed together. The next most common is blood type A, then B, and the rarest is blood type AB.
