What is the likelihood of finding a match?

A patient’s likelihood of finding a donor match on Be The Match Registry® ranges from 66% to 97%, depending on ethnic background. Because the markers used in matching are inherited, patients are most likely to match someone of the same ethnic ancestry.

Some ethnic groups have more complex tissue types than others. This is especially true for people who identify as multiracial. Adding more potential donors and cord blood units to increase the ethnic diversity of the registry in some cases, will increase the variety of tissue types available, helping more patients find the match they need. Adding more potential donors and cord blood units to increase the ethnic diversity of the registry remains an important focus for Be The Match®.
