This blood test is used for the diagnosis of rheumatoid arthritis. High levels of rheumatoid factor in the blood are most often associated with autoimmune diseases, such as rheumatoid arthritis and Sjogren’s syndrome.
No specific patient preparation protocol required. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing this test.
Rheumatoid factor (RF) is an autoantibody, an immunoglobulin M (IgM) protein that is produced by the body’s immune system. Autoantibodies attack a person’s own tissues, mistakenly identifying the tissue as “foreign.”
This test detects and measures RF in the blood and may be used, along with other tests, to help in the diagnose of rheumatoid arthritis (RA).
