HLA Typing

HLA stands for human leukocyte antigen. Human leukocyte antigens are protein molecules that are inherited. HLA typing is the process of testing blood or other tissue samples from a patient who needs a transplant and from any potential donor to see how closely they match. The more HLA molecules two people share, the better the match. When two people share the same HLA molecules, their immune systems will not see each other as foreign and are less likely to attack each other.
