An ANA 11 Components (no ANA Screen) test is a blood test that measures the level of specific autoantibodies in the blood. Autoantibodies are antibodies that attack the body’s own cells and tissues, and the presence of certain autoantibodies can indicate the presence of an autoimmune disease. Here are some reasons why you might need an ANA 11 Components (no ANA Screen) test:
Suspected autoimmune disease: An ANA test is often used as a screening test for autoimmune diseases, such as lupus, rheumatoid arthritis, and scleroderma. An ANA 11 Components test is more specific than a general ANA screen and can help to identify specific autoantibodies that are associated with certain autoimmune diseases.
Monitoring disease progression: An ANA 11 Components test can be used to monitor the progression of autoimmune diseases and the effectiveness of treatment. Changes in autoantibody levels can indicate changes in disease activity, and the test can be used to adjust treatment accordingly.
Differential diagnosis: The symptoms of autoimmune diseases can be similar to other medical conditions, and an ANA 11 Components test can be used to help differentiate between these conditions. The test can help to confirm a diagnosis of autoimmune disease and rule out other possible causes of symptoms.
Your healthcare provider will determine whether an ANA 11 Components (no ANA Screen) test is necessary based on your individual medical history and symptoms. The test typically includes tests for specific autoantibodies, such as anti-dsDNA, anti-SSA, anti-SSB, anti-Sm, anti-Ro/SSA, anti-La/SSB, anti-Jo-1, anti-Scl-70, anti-centromere B, anti-RNP, and anti-histone.
