About Rheumatoid Factor (RA) Test - Arthritis in Addison
Rheumatoid factor testing is a blood test used to detect and measure autoantibodies directed against the body's own immunoglobulins.
Rheumatoid factor is not a single molecule but a family of antibodies, most commonly of the IgM class, that bind to the Fc portion of IgG. Although IgM rheumatoid factor is the form usually measured, IgA and IgG rheumatoid factor can also be elevated in people with rheumatoid arthritis and may correlate with more active disease.
The test is most useful when a patient has signs and symptoms consistent with rheumatoid arthritis, such as symmetric joint pain, morning stiffness, and swelling of the small joints of the hands and feet. A positive result supports the diagnosis but is not sufficient on its own, because rheumatoid factor can also appear in other autoimmune conditions, chronic infections, and in some healthy individuals, particularly older adults.
Because rheumatoid factor lacks perfect specificity, clinicians often interpret it alongside the patient's history, physical examination, inflammatory markers, and other autoantibodies such as anti-cyclic citrullinated peptide. Serial measurements may be used to track disease activity, though treatment decisions rely on the full clinical picture rather than a single laboratory value.
