About Rheumatoid Factor (RA) Test - Arthritis in La Quinta
Rheumatoid factor testing measures the presence and level of these autoantibodies in the blood.
Rheumatoid factor belongs to a family of antibodies called immunoglobulins. The most commonly detected form is IgM rheumatoid factor, though IgA and IgG forms also occur and have been studied in people with rheumatoid arthritis. The test reports whether rheumatoid factor is present and, in many cases, how much is present.
Rheumatoid factor is not exclusive to rheumatoid arthritis. It can appear in other autoimmune conditions, in some chronic infections, and in a proportion of healthy people, especially with advancing age. Because of this, a positive result on its own does not confirm rheumatoid arthritis, and a negative result does not rule it out.
Clinicians interpret rheumatoid factor alongside symptoms, physical examination, and other laboratory findings such as anti-cyclic citrullinated peptide antibodies and inflammatory markers. Used in context, the test helps build a fuller picture of what is driving joint pain, swelling, or stiffness.
