What Does ANA Stand For?
ANA stands for Antinuclear Antibody
ANA, or Antinuclear Antibody, refers to a type of autoimmune antibody that targets components within the nucleus of cells. The presence of ANAs in the bloodstream is commonly associated with various autoimmune disorders, including systemic lupus erythematosus, rheumatoid arthritis, and Sjögren's syndrome. Testing for ANA is often used as a diagnostic tool to help identify these conditions, as elevated levels can indicate an autoimmune response. However, ANAs can also be present in healthy individuals, making further clinical evaluation necessary for accurate diagnosis.
