Human Leukocyte Antigen (HLA) is a group of protein complexes that regulate our immune system and enable our bodies to respond to foreign substances. These antigens consist of specialized proteins found on the surface of cells and are genetically determined. In cases like organ transplantation and stem cell transplantation, HLA typing is done to determine the compatibility between the donor and the recipient. This is crucial to minimize the risk of rejection after the transplant. The higher the HLA compatibility, the higher the chances of a successful outcome after transplantation.
