Organs from every donor are matched with people on the waiting list based on: blood type body size how sick they are donor distance tissue type A pancreas match depends on how well the blood types match. Because of the way chromosomes/DNA are inherited or passed down in a family, a parent and child would have at least a 50 percent chance of matching, siblings could have a zero to 100 percent match, and unrelated donors would be less likely to match at all. Matching Donors and Recipients | organdonor.gov how bad the patient's medical condition is; the distance between the donor's and the patient's hospital; the patient's waiting time; and if the patient is available. Of course now there are immunosuppressive medications used to prevent rejection and this has made it possible for even zero-antigen matches to have good outcomes. OPOs become involved when a patient is identified as a potential donor. Potential donors should: 2 . Each applies to kidneys from both live and deceased donors.
