Transplant Center HLA Match Requirements

Different transplant centers accept different levels of patient and donor matching for a bone marrow or cord blood transplant. You can find the match level of specific centers in the National Marrow Donor Program (NMDP) U.S. transplant center listings under Match Level.

Match levels

When a transplant center looks at the match level, it is looking at how alike the human leukocyte antigen (HLA) tissue types of the patient and the donor are to each other. HLA is a term used to describe protein markers that are found on most of the body's cells. These protein markers help identify a person's tissue type. Your immune system uses HLA to recognize which cells belong in your body and which do not. The HLA proteins are important in matching patients and donors for a bone marrow, peripheral blood cell (PBSC) or cord blood transplant.

See HLA Matching: Finding the Best Donor or Cord Blood Unit to learn more about HLA and how transplant centers use it to help select the best available donor or cord blood unit for a patient.

To view the number of potential donors and cord blood units you may have on the NMDP Registry, see MatchViewSM. MatchView also includes information to help you understand HLA matching and the next steps in the search and transplant process.
