HLA Typing (Human Leukocyte Antigen Typing)

HLA typing, or Human Leukocyte Antigen typing, is a medical test that identifies specific markers on the surface of cells in the immune system. These markers play a crucial role in how the body recognizes its own tissues versus foreign ones, such as in organ transplants. By matching HLA types between donors and recipients, doctors can reduce the risk of organ rejection. HLA typing is also important in conditions like autoimmune diseases and some blood cancers, helping to understand how the immune system functions and how to tailor treatments effectively.
