The reported titer will be the last titer read before the negative result. Fluorescence techniques are frequently used to actually detect the antibodies in the cells, thus ANA testing is sometimes referred to as fluorescent antinuclear antibody test (FANA). "ANA."
What non-autoimmune conditions produce ANAs?
This Lupus Quiz covers causes, signs, symptoms, facts, and treatments for this inflammatory autoimmune disease. The ANA blood test reveals the presence of antinuclear antibodies in the blood. The diagnosis of Sjögren's syndrome is often challenging because patients often present with nonspecific complaints such as fatigue, joint ache and swelling, abdominal pain, and diarrhea (as well as the classic dry eyes and dry mouth). Determine the test result by the use of either indirect immuno-fluorescence microscopy or ELISA (enzyme-linked immunoabsorbant assay).

ANAs present different "patterns" depending on the staining of the cell nucleus in the laboratory: homogeneous or diffuse pattern; speckled pattern; nucleolar pattern; and peripheral or rim pattern.

For example, the nucleolar pattern is more commonly seen in the disease scleroderma. Autoimmune diseases are conditions in which there is a disorder of the immune system characterized by the abnormal production of antibodies (autoantibodies) directed against the tissues of the body.
