When it comes to matching human leukocyte antigen (HLA) types, a person is more likely to find a donor from the same racial or ethnic background. This is because HLA markers used in matching are inherited. Some combinations of these markers are more common in some racial groups than others. So a person’s best chance of finding a donor may be with someone who shares a similar ancestry.
