How organ matching works
UNOS’ computer system stores information about every person who is waiting for a transplant, and matches donor organs with transplant candidates 24 hours a day, 365 days a year. When a patient is “added to the list,” a transplant hospital adds a patient’s medical information into UNOS’ computer system. The patient is not immediately placed on a ranked list. When a deceased organ donor is identified, UNOS’ computer system generates a ranked list of transplant candidates who are suitable to receive each organ. Factors affecting ranking may include blood type, tissue type, medical urgency, waiting time, expected benefit, geography and other criteria. Learn more >
