Antinuclear Antibodies (ANA) are autoantibodies directed against components of the cell nucleus. ANA positivity is common in autoimmune diseases and is a hallmark of systemic lupus erythematosus (SLE) and other rheumatic conditions.
A venous blood sample is analyzed for antinuclear antibody levels. Common methods include Indirect Immunofluorescence (IFA) and ELISA. Results should be interpreted together with tests such as ENA and anti-dsDNA antibodies.
Q1: Does a positive ANA always mean disease?
A: No. Some healthy individuals may have low-titer ANA, so results must be correlated with clinical findings.
Q2: Can ANA alone confirm lupus?
A: No. Further tests such as anti-dsDNA and ENA are required for diagnosis.
Q3: Which diseases are commonly ANA positive?
A: SLE, Sjögren’s syndrome, scleroderma, and mixed connective tissue disease.
