The National Marrow Donor Program (NMDP) and Be The Match Foundation (the fundraising partner of NMDP) are nonprofit organizations dedicated to creating an opportunity for all patients to receive the bone marrow or umbilical cord blood transplant they need, when they need it. The NMDP operates the Be The Match Registry, the world’s largest and most diverse registry of volunteer marrow donors and donated cord blood units. A patient's doctor can contact the NMDP to search the Be The Match Registry, which provides a single point of access to 8 million potential donors and 160,000 cord blood units. There is additional access to more than 5 million donors and 240,000 cord blood units listed on international registries. The NMDP Office of Patient Advocacy supports patients and their families from diagnosis through survivorship by providing information, referrals, and support.
