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.

Autoantibodies may be the cause of an autoimmune disease but usually, autoantibodies are just a sign of the disease, not the reason. They can be detected in the blood, e.g. with EliA blood tests and serve as diagnostic markers for specific autoimmune diseases.


As in all diagnostic testing, the diagnosis is made by the physican based on both test results and the patient history.
