The ANA blood test is one of many screening tests for autoimmune disorders. Find out how this test helps doctors to identify invisible illnesses that cause chronic pain and other symptoms and learn what your test results mean.
ANA testing is very useful in establishing a diagnosis of systemic lupus erythematosus (SLE). Nearly all patients with SLE have a positive ANA test, with a sensitivity of 93% to 95% and a specificity of 57%. However, even healthy persons can have a positive ANA test at lower titers. About 25% to 30% of healthy persons have a positive test with a titer of 1 : 40, 10% to 15% at a titer of 1 : 80, and 5% at a titer of 1 : 160 or greater. The frequency increases with age, particularly in women.
