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.
