  2. Autoimmune hepatitis - Wikipedia

    en.wikipedia.org/wiki/Autoimmune_hepatitis

    Type 1 autoimmune hepatitis. Positive antibodies include: [19] [20] Antinuclear antibody (ANA) Anti-smooth muscle antibody (ASMA) - 65% of people; Anti-actin antibodies; Anti-mitochondrial antibodies - rare except for overlap syndromes with primary biliary cholangitis; Anti-soluble liver antigen/liver pancreas antibody antigen - 20% of people

    [10] On the other hand, they say, although 95% of the patients who actually have lupus test positive for ANA, "Only a small percentage have a negative ANA, and many of those have other antibodies (such as anti-phospholipid antibodies, anti-Ro, anti-SSA) or their ANA converted from positive to negative from steroids, cytotoxic medications, or ...

  4. Undifferentiated connective tissue disease - Wikipedia

    en.wikipedia.org/wiki/Undifferentiated...

    Patients with UCTD usually have positive ANA (antinuclear antibody), and raised ESR (erythrocyte sedimentation rate) values, without typical autoantibody specificities. [14] Some 20% of the general population, [ 15 ] and up to 15% of completely healthy people, [ 16 ] test positive for ANA, but nonetheless this is regarded by some as almost ...

  5. Autoimmune pancreatitis - Wikipedia

    en.wikipedia.org/wiki/Autoimmune_pancreatitis

    These antibodies are postulated to provoke an immune response against these ancinar cells resulting in pancreatic inflammation and destruction. [5] Knowing the auto-antigens involved would allow early diagnosis of the disease, its differentiation from a diagnosis of pancreatic cancer, and potentially even prevention, but unfortunately these ...

  6. Anti-histone antibodies - Wikipedia

    en.wikipedia.org/wiki/Anti-histone_antibodies

    A value of greater than 1.5 units relative to a control serum is considered a positive ELISA test for the anti-histone antibodies. Patients with drug-induced lupus erythematosus typically have positive tests for anti-histone antibodies but do not have indications for anti-dsDNA antibodies. Patients with idiopathic systemic lupus erythematosus ...

  7. Anti-SSA/Ro autoantibodies - Wikipedia

    en.wikipedia.org/wiki/Anti-SSA/Ro_autoantibodies

    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 ...

    Indeed, in 84.3% of positive anti-ENA samples, ANA reagents were also found. [1] The use of anti-ENA autoantibody tests can serve as additional verification of an autoimmune disorder, because a positive ANA test alone does not suffice for diagnosis. In fact, low levels of ANAs can be found in healthy patients.

  9. Anti-dsDNA antibodies - Wikipedia

    en.wikipedia.org/wiki/Anti-dsDNA_antibodies

    Anti-double stranded DNA (Anti-dsDNA) antibodies are a group of anti-nuclear antibodies (ANA) the target antigen of which is double stranded DNA. Blood tests such as enzyme-linked immunosorbent assay (ELISA) and immunofluorescence are routinely performed to detect anti-dsDNA antibodies in diagnostic laboratories.
