About Rheumatoid Factor (RA) Test - Arthritis in Lancaster
Rheumatoid factor testing measures the concentration of this autoantibody in a blood sample.
Rheumatoid factor belongs to the immunoglobulin family. The most commonly measured form is IgM rheumatoid factor, though IgA and IgG rheumatoid factor have also been studied in people with rheumatoid arthritis.
Rheumatoid factor is not exclusive to rheumatoid arthritis. It can appear in other inflammatory and autoimmune conditions, in some chronic infections, and in a proportion of healthy individuals, particularly as they age.
Because of this overlap, rheumatoid factor results are interpreted alongside a person's symptoms, physical examination, and other laboratory findings rather than as a standalone diagnostic marker.
