Reference range: 0–0 (Source: ABIM)
High values may indicate
A positive ANA result may indicate an autoimmune condition such as systemic lupus erythematosus (SLE), Sjögren's syndrome, scleroderma, or mixed connective tissue disease. Further testing is required to confirm a diagnosis.
Low values may indicate
A negative ANA result makes most autoimmune conditions less likely, though clinical correlation is still needed.
