Skin tests, such as the autologous serum skin test (ASST), can be used to detect the presence of functional autoantibodies. In this test, a small amount of the patient's serum is injected into the skin. A positive reaction, which is the formation of a wheal and flare, indicates the presence of functional autoantibodies.

This article provides a list of autoimmune diseases. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed ...
An autoantibody is an antibody ... Coeliac disease (antibody levels correlate with the level of intestinal damage [8] [9]), autoimmune hepatitis, gastric cancer:
Autoantibody testing: Many autoimmune diseases are characterized by the presence of autoantibodies. Blood tests can identify these antibodies, which are directed against the body's own tissues. [66] For example, antinuclear antibody (ANA) testing is commonly used in the diagnosis of systemic lupus erythematosus and other autoimmune diseases.
In systemic lupus there are autoantibodies to DNA, which cannot evoke a T cell response, and limited evidence for T cell responses implicates nucleoprotein antigens. In Celiac disease there are autoantibodies to tissue transglutaminase but the T cell response is to the foreign protein gliadin.
The main symptoms include several kinds of skin rash along with muscle weakness in both upper arms or thighs. [8] Although dermatomyositis is closely related to polymyositis and is sometimes assumed to be a complication of that disease, most patients with dermatomyositis develop skin symptoms before any muscle involvement.
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
Dermatomyositis: an inflammatory disease of skin and muscle marked especially by muscular weakness and skin rash. Scleroderma is a connective tissue disease that causes fibrosis and vascular abnormalities, but that also has an autoimmune component, and can include connective tissues complications.
