What is the confirmatory test for lupus?

98% of all people with systemic lupus have a positive ANA test, making it the most sensitive diagnostic test for confirming diagnosis of the disease. The test for anti-nuclear antibodies is called the immunofluorescent antinuclear antibody test. In this test, a blood sample is drawn and sent to a laboratory.

What are the biomarkers for lupus?

Significantly, T-cell surface levels of CD44v3 and CD44v6 were found to be correlated with the SLEDAI score, positivity of anti-dsDNA, and the presence of lupus nephritis. These results suggest that expression levels of CD44v3 and CD44v6 on T cells may serve as biomarkers for SLE disease activity [Crispin et al.

What tests are used to diagnose systemic lupus erythematosus?

Antinuclear antibody titer is the primary laboratory test used to diagnose systemic lupus erythematosus. Because of the low prevalence of the disease in primary care populations, the antinuclear antibody titer has a low predictive value in patients without typical clinical symptoms.
