If you need an allogeneic transplant, the cells you receive will come from someone else. Your doctor will look for a donor in your family who matches your human leukocyte antigens, or HLA, type. These are markers your body uses to know which cells belong in your body and which don't.
HLA tissue types are inherited, so your best chance of finding a match is with a brother or sister who have the same two biological parents. However, 70% of patients do not have a suitable donor in their family. If you do not have a donor in your family, your doctor can search for a marrow donor or cord blood unit.
The registry of the C.W. Bill Young Cell Transplantation Program, also called the Be The Match Registry®, is a listing of potential marrow donors and donated cord blood units. The registry is operated under Federal contracts by the National Marrow Donor Program (NMDP).
Find more information about The Search Process, including when your doctor may begin to search a listing of potential marrow donors and cord blood units throughout the world. NMDP/Be The Match has agreements with its global partners to provide access to more than 35 million potential marrow donors and nearly 783,000 cord blood units within its search system.

It can take a few weeks to a few months or more to find a marrow donor or cord blood unit. However, sometimes a matching marrow donor or cord blood unit cannot be found. If your doctor cannot find a suitable match for you, they will look at other treatment options.
Sometimes, family and friends want to help by adding more donors to the registry. Be The Match can help with donor recruitment efforts.
