    There is an association between rheumatoid factor and more persistently active synovitis, more joint damage, greater eventual disability and arthritis. [12] [13] Other than in rheumatoid arthritis, rheumatoid factor may also be elevated in other conditions, including: Systemic lupus erythematosus (SLE) [14] [15] Sjögren syndrome [14] [15]

  3. Heterophile antibody - Wikipedia

    en.wikipedia.org/wiki/Heterophile_antibody

    It is present in 80% of infected teens and adults, 40% of all infected children, and only 20% of infected children under age four. Heterophile antibodies can arise in non-EBV infections. False positive monospot tests may occur in cases of HIV, lymphoma, or systemic lupus erythematosus. Other assays for detection of EBV are available, including ...

  4. Anti-histone antibodies - Wikipedia

    en.wikipedia.org/wiki/Anti-histone_antibodies

    Ninety-six percent of patients with lupus induced by procainamide will have a positive test for anti-histone antibodies, and 100% of patients whose lupus was induced by penicillamine, isoniazid, or methyldopa will have a positive test for anti-histone antibodies. In 70% of patients with rheumatoid arthritis, Felty's syndrome, Sjogren's syndrome ...

    For example, IgM-rheumatoid factor (IgM-RF) have been shown to cross-react with ANA giving falsely positive immunofluorescence. [64] Positive ANA as well as anti-DNA antibodies have been reported in patients with autoimmune thyroid disease.

  6. Autoantibody - Wikipedia

    en.wikipedia.org/wiki/Autoantibody

    ANA is a marker of the autoimmune process – it is positive with a variety of different autoimmune diseases but not specific. Consequently, if an ANA test is positive, it is often followed up with other tests associated with arthritis and inflammation , such as a rheumatoid factor (RF), an erythrocyte sedimentation rate (ESR), a c-reactive ...

    en.wikipedia.org/wiki/D-dimer

    False positive readings can be due to various causes: liver disease, high rheumatoid factor, inflammation, malignancy, trauma, pregnancy, recent surgery as well as advanced age. [21] False negative readings can occur if the sample is taken either too early after thrombus formation or if testing is delayed for several days. Additionally, the ...

    Their significance is greater than that of rheumatoid factor. Recently a serological point-of-care test (POCT) for the early detection of RA has been developed. This assay combines the detection of rheumatoid factor and anti-MCV for diagnosis of rheumatoid arthritis and shows a sensitivity of 72% and specificity of 99.7%. [4] [5]
