How organ matching works

Understand the basic path to donation

When a patient is “added to the list,” a transplant hospital adds a patient’s medical information into UNOS’ computer system. When a deceased organ donor is identified, UNOS’ computer system generates a ranked list of transplant candidates, or “matches”, based on blood type, tissue type, medical urgency, waiting time, expected benefit, geography and other medical criteria.
