Antinuclear Antibody (ANA) Blood Test

Item # LC164855

Antinuclear antibody (ANA) blood testing is used in the screening of autoimmune disorders such as rheumatoid arthritis, scleroderma, Sjögren’s syndrome and systemic lupus erythematosus.

This test detects antibodies to nuclear antigens. It is ordered to help screen for autoimmune disorders such as rheumatoid arthritis, scleroderma and Sjögren’s syndrome. Additionally, it is most often used as one of the tests to diagnose systemic lupus erythematosus (SLE).


Fasting is not required for this test. Take all medications as prescribed.


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 a known disease.

This test provided me with some important information. It was nice to have the opportunity to get this information without a long wait.


I have to check ANA periodically and can do it without doctor's referral.
