| Definition |
Proteins on white blood cells that make each person´s tissue unique. The HLA A, B and DR proteins are important in matching patients and donors for a marrow or blood stem cell transplant.
a set of 6 antigens used to match a blood or bone marrow donor to a recipient. These antigens appear on white blood cells as well as cells of almost all other tissues and are analogous to red blood cell antigens (type A, B, O, etc.) By typing for HLA antigens, donors and recipients of white blood cells, platelets, and organs can be matched to ensure good performance and survival of transfused and transplanted cells.
