False! 1 in 430 members of the Be The Match Registry® (Registry in the United States) will go on to donate bone marrow or peripheral blood stem cells to a patient. Due to tissue diversity, there is no prediction of the likelihood of donation. You may never be identified as a match for someone OR you might be one of a number of potential matches. Either way, you may be the only one on the Registry who can save a particular patient’s life.
