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.

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


Your HLA—your tissue typing—is inherited from your ancestry. This is why patients are most likely to match someone of the same ethnic ancestry. Adding more members who increase the ethnic diversity of the registry increases the variety of tissue types available, helping more patients find the match they need.


Registry members are listed on Be The Match Registry until their 61st birthday. However, doctors request donors in the 18 to 35 age group more than 75% of the time. Research shows that younger donors provide the greatest chance for transplant success.
