WebJun 23, 2024 · In the antinuclear antibody (ANA) test, antinuclear (or anti-cytoplasmic) antibodies bind to cells that have been fixed on a slide. The addition of a secondary antibody (with an attached fluorescent dye) directed against human antibodies may reveal staining of the nucleus or cytoplasm under a fluorescence microscope. WebJun 2, 2024 · These staining patterns appear as a result of the adhesion of autoantibodies to certain nuclear antigens. Although ANAs are specific to nuclear antigens, in some cases, cytoplasmic patterns correlated with autoantibodies against cytoplasmic antigens can also be visualized. Sometimes, a mixed pattern can be observed. diasystematic
