In blood transfusion, which was the earliest and is still the most common tissue transplant, blood must be matched for ABO and Rh blood group antigens to avoid the rapid destruction of mismatched red blood cells by antibodies (see Appendix I, Section A-11 ). For cord blood transplants a perfect HLA match doesn't seem to be as important, and even a sample with a couple of mismatched antigens may be OK. Doctors keep learning more about better ways to match . The Rh factor is not important. For each organ that becomes available, the computer program generates a list of potential recipients ranked according to objective criteria (i.e. The pancreas can survive outside the body for 12 to 18 hours.
