The role of autoantibodies

As soon as the immune system attacks the body’s own cells, the production of autoantibodies is initiated. Autoantibodies are blood proteins directed against the body's own parts.

Autoantibodies can affect every organ, from the hair root cells to the kidney, and can sometimes cause complete destruction of the target organs.

Although autoantibodies may be the cause of an autoimmune disease, they are usually just a sign of the disease, not the reason. They can be detected in the blood, for example with EliA blood tests, and act as diagnostic markers for specific autoimmune diseases.
