Quizplus · Accepted Answer

Antinuclear antibodies (ANAs) are present in a variety of immunologic diseases including systemic lupus erythematosus (SLE), rheumatoid arthritis, scleroderma, and Sjögren syndrome. ANAs are antibodies that recognize and bind to various components within the nucleus of a cell, and their presence can be detected through various laboratory tests. Alkaline phosphatase (A), c-reactive protein (B), and uric acid (D) may be elevated in certain inflammatory conditions, but are not specific to immunologic diseases.
