Human leukocyte antigen (HLA) typing is a DNA-based tissue test used to match patients and donors for bone marrow and blood stem cell transplants. HLA are proteins — or markers — found on most cells in your body
Your immune system uses these markers to recognize which cells belong in your body and which do not. The closer the match the better the chances the patient’s body will accept the donated cells and allow them to grow and make new healthy cells.
