Antinuclear Antibody (ANA)
Item Catalog Number: LC164855
This test detects antibodies to nuclear antigens. The ANA test is ordered to help screen for autoimmune disorders such as rheumatoid arthritis, scleroderma and Sjögren’s syndrome. It is most often used as one of the tests to diagnose systemic lupus erythematosus (SLE).
Although a positive ANA result may suggest an autoimmune disorder, the test can be positive in people with allergies as well as older populations without known disease.
You can check for ANA antibodies with or without fasting. This test is not included in any other Life Extension Panel.
