An allogeneic transplant uses blood-forming cells donated by someone else. This could be a family member, someone unrelated to you, or a cord blood unit (CBU). Cord blood is the blood collected from the umbilical cord and placenta after a baby is born.

You don’t have to find your own donor or CBU. Typically, your doctor will first look for a matched donor in your family—usually a brother or sister. About 70% (7 out of 10) of patients who need a transplant don’t have a matched donor in their family. If you don’t have a match in your family, your doctor will search the Be The Match Registry® to find a matched unrelated donor or CBU for you.

HLA Matching

Your transplant doctor will look for a donor or cord blood unit whose human leukocyte antigens (HLA) closely matches yours. HLA are proteins – or markers – found on most cells in your body. Read more about HLA matching.

Searching the Registry®

If you don’t have a match in your family, your doctor will search the Be The Match Registry to find a matched unrelated donor or cord blood unit. Depending on your ethnic background, the chance of finding a match is between 66% and 99%. Read more about the registry.

MatchView ®

MatchView is an online tool that gives an estimate of how many of the potential donors and cord blood units that are currently on the Be The Match Registry might match you.
