Show HLA matching is used to match patients and donors for blood or marrow transplants. If 2 people share the same HLA type, they are considered a 'match'. It's much more complicated than blood typing. How does matching happen?
What are my chances of having a match?There are many HLA markers. Each HLA marker has a name. The names are letters or combinations of letters and numbers. Sometimes, it’s hard to find a match because some HLA types are less common. HLA types are inherited so siblings can sometimes be a match for each other.

Usually, it’s a donor or CBU whose HLA are very closely matched to yours. A close match is important because it:
There are times when a closely matched donor isn’t the best option. For some patients, a donor who matches exactly half of their HLA is best. This is called a haploidentical (or half-matched) transplant.
