Positive ANA may be found in apparently healthy people. It is therefore imperative that the results be interpreted in light of the patient’s clinical picture by a medical authority. SLE patients undergoing steroid therapy may have negative test results. Many commonly prescribed drugs may induce ANA. The ZEUS ELISA ANA Screen Test System will not identify the specific type of ANA present in a ...

Testing for antibodies against nuclear antigens can be helpful in the diagnosis of diseases such as systemic lupus erythematosus and scleroderma. The National Consensus Conference on Guidelines for ANA testing was published by Kavanaugh et al. in January, 2000.1 Those Guidelines stress that improper use of ANA testing can lead to misinformation, incorrect diagnoses, and a waste of limited ...

Antinuclear antibodies (ANA) are frequently present in patients with systemic lupus erythematosus (SLE) and, less commonly, in other autoimmune diseases Rheumatoid arthritis, Collagen vascular diseases, chronic liver diseases and systemic sclerosis (scleroderma). ANA bind to several nuclear antigens including DsDNA, SSDNA, RNP, Sm, SSA and SSB.

That said, only about 11-13 percent of persons with a positive ANA test have lupus and up to 15 percent of completely healthy people have a positive ANA test. Thus a positive ANA test does not automatically translate into a diagnosis of lupus or any autoimmune or connective tissue disease. FANA test results are reported in titers and the patterns that the autoantibodies make, e.g., homogeneous ...

A positive ANA is seen in 98 to 99% of patients with SLE. The specificity is low as ANA positivity is seen in up to 15% of the population and more so in patients with chronic infections. A positive ds- DNA is highly specific for lupus and higher titres are seen in patients with renal involvement. Anti- Ro and Anti – La antibodies are seen in subacute cutaneous lupus as well as in SLE where ...

Anti-dsDNA was positive in 8.7% of ANA positive patients in the study. The major pattern of anti-dsDNA positive samples was homogeneous (68.8%). The most seen pattern from SLE disease is homogeneous (60-70%) which shows the autoantibody presence against dsDNA and our results were parallel to the literature (1, 17, 20). On the other hand, it must be considered that homogeneous pattern may also ...

A positive ANA in a patient who you do not think has SLE and who only has 1 of the diagnostic symptoms is most likely to be a NON-SPECIFIC FINDING. ANA alone has a low positive predictive value for SLE so it is unlikely to be useful in patient populations with a low prevalence of systemic lupus erythematosus (e.g. the elderly).
