Which abbreviation stands for Antinuclear Antibody?

• A. RF
• B. ANCA
• C. ANA
• D. Anti-dsDNA

Answer: (C)

ANA stands for Antinuclear Antibody, the autoantibody directed against components of the cell nucleus. This abbreviation is used for a broad screening test in autoimmune diseases such as lupus and other connective tissue disorders, though a positive result is not specific to one disease and can occur in healthy individuals as well. Other common abbreviations refer to different antibodies: RF is rheumatoid factor, ANCA is anti-neutrophil cytoplasmic antibodies, and anti-dsDNA are antibodies against double-stranded DNA. In short, the term you’re looking for is ANA, which literally means Antinuclear Antibody.
