Anti-Nuclear Antibody / Factor (ANA/ANF), EIA ( Offer )

The Anti-Nuclear Antibody / Factor (ANA/ANF), EIA (Offer) test is a specialized blood test used to detect anti-nuclear antibodies (ANA), which are autoantibodies produced when the immune system mistakenly attacks the body’s own healthy cells. These antibodies target the nucleus of cells and are commonly associated with autoimmune diseases. The test is performed using the Enzyme Immunoassay (EIA) method and serves as an important screening tool for evaluating autoimmune disorders.

The ANA/ANF test is commonly recommended for individuals experiencing symptoms such as persistent joint pain, chronic fatigue, unexplained fever, skin rashes, muscle pain, or other signs suggestive of autoimmune disease. It helps support the diagnosis of conditions including Systemic Lupus Erythematosus (SLE), Rheumatoid Arthritis, Sjögren’s Syndrome, Scleroderma, and other connective tissue disorders. Although a positive ANA result may indicate an autoimmune condition, it does not confirm a diagnosis on its own, as positive results can also occur in healthy individuals or other medical conditions. Therefore, ANA results should always be interpreted alongside the patient’s symptoms, medical history, physical examination, and additional laboratory tests such as Anti-dsDNA, Anti-Smith antibodies, and other autoimmune markers. This test also plays an important role in monitoring patients already diagnosed with autoimmune diseases and guiding appropriate treatment decisions.
