    Positive ANA as well as anti-DNA antibodies have been reported in patients with autoimmune thyroid disease. [ 65 ] [ 66 ] ANA can have a positive test result in up to 45% of people with autoimmune thyroid conditions or rheumatoid arthritis and up to 15% of people with HIV or hepatitis C .

  4. Extractable nuclear antigen - Wikipedia

    en.wikipedia.org/wiki/Extractable_nuclear_antigen

    An extractable nuclear antigen panel, or an ENA panel, tests for presence of autoantibodies in the blood that react with proteins in the cell nucleus. It is usually done as a follow-up to a positive antinuclear antibody test and when one is showing symptoms of an autoimmune disorder. The ANA tests for the presence or absence of autoantibodies ...

    Autoantibody tests may be ordered as part of an investigation of chronic progressive arthritis type symptoms and/or unexplained fevers, fatigue, muscle weakness and rashes. The antinuclear antibody (ANA) test is often ordered first. ANA is a marker of the autoimmune process – it is positive with a variety of different autoimmune diseases but ...

    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.

    Anti-double stranded DNA (Anti-dsDNA) antibodies are a group of anti-nuclear antibodies (ANA) the target antigen of which is double stranded DNA.

    Antinuclear antibody (ANA) testing and anti-extractable nuclear antigen form the mainstay of serologic testing for SLE. ANA testing for lupus is highly sensitive, with the vast majority of individuals with Lupus testing positive; but the test is not specific, as a positive result may or may not be indicative of Lupus.
