What is a HLA Typing test?

HLA typing, or Human Leukocyte Antigen typing, is a test that identifies the specific proteins on the surface of human cells. These proteins, called human leukocyte antigens (HLAs), play a crucial role in the immune system. HLA molecules help the immune system distinguish between the body’s own cells and foreign substances, such as bacteria or viruses.

The HLA typing test is primarily performed to assess the compatibility between the tissues of a donor and recipient, especially in the context of organ or tissue transplantation. Matching HLA types between a donor and recipient increases the likelihood of a successful transplant by reducing the risk of rejection.

HLA typing is also important in the field of immunology and research, as variations in HLA genes can be associated with certain autoimmune diseases and conditions. Understanding HLA types helps researchers investigate the genetic basis of immune-related disorders.
