Rheumatoid Factor Test

The rheumatoid factor (RF) test is a blood test that detects an antibody often present in patients with rheumatoid arthritis, an autoimmune condition that causes joint inflammation, pain and swelling. While a positive result supports a diagnosis of rheumatoid arthritis, it is not fully specific, as RF can also be positive in other autoimmune diseases or even in some healthy individuals, so it is always interpreted alongside clinical findings and other tests. It is commonly ordered together with the anti-CCP antibody test for a more complete picture, as the two tests together improve diagnostic accuracy. The test is also occasionally used to monitor disease activity, though it is less useful for this purpose than for initial diagnosis.
