You could be someone’s cure 

Be The Match® can’t predict what your individual chance of donating to a patient might be. But it’s important to remember that you could be the only person who could save someone’s life. Every registry member is important to patients in need of a marrow transplant.

Donation statistics

  • 1 in 40 registry members will be called for additional testing. Additional testing can be used to narrow the list of potential donors and determine the best possible match for a patient.
  • 1 in 300 will be selected as the best possible donor for a patient. These potential donors will have an information session with their donor center representative to learn more about the donation process. Due to changes in the patient's condition, not all donors who are selected as the best match will donate.
  • About 1 in 540 members will actually donate.

Two important factors in matching marrow donors to patients: Age and ancestry


Your HLA - your tissue typing -is inherited from your ancestry.  Patients are most likely to match someone of their own race or ethnicity. People of diverse racial and ethnic backgrounds are especially needed on the registry so that every patient has a chance for a cure.


Registry members are listed on Be The Match Registry until their 61st birthday. However, doctors request donors in the 18 to 44 over age group 90% of the time. Research shows that younger donors provide the greatest chance for transplant success.
