Experiencing joint pain, stiffness, or swelling? This test measures rheumatoid factor (RF), an antibody that can indicate autoimmune conditions such as rheumatoid arthritis. While rheumatoid factor is commonly elevated in rheumatoid arthritis, it can also be present in other inflammatory or autoimmune disorders.

Test limitations
This test helps detect rheumatoid factor but does not diagnose rheumatoid arthritis or other autoimmune diseases on its own. Some people without rheumatoid arthritis may have elevated RF, while some with rheumatoid arthritis may test negative. Further tests, such as anti-CCP antibodies or inflammatory markers, may be needed for a complete assessment.
