Antinuclear Antibodies (ANA) An ANA is an antibody against a nuclear component of the cell. At Clinipath Pathology, the test is performed by immunofluorescence, and a titre is given, as well as the pattern of the fluorescence. The ANA may represent many autoantibodies, so once an ANA is found, often further testing needs to be

A positive ANA test result may suggest an autoimmune disease, but further specific testing is required to assist in making a final diagnosis. ANA test results can be positive in people without any known autoimmune disease. While this is not common, the frequency of a false positive ANA result increases as people get older.

ANA levels could change from positive to negative and back again. I have illustrated a very common way that ANA may appear to change from positive to negative. There is one situation, discussed later, where ANA levels truly can drop dramatically and perhaps become negative, but let's first take a look at the more general question of how ANA and
