Order Rheumatoid Factor (RA) Test - ArthritisThe rheumatoid factor test is a blood test that detects an autoantibody commonly associated with rheumatoid arthritis. It is one of several tools clinicians use when evaluating persistent joint pain, swelling, and stiffness, and it is interpreted alongside symptoms, physical examination, and other laboratory findings rather than as a stand-alone diagnosis.
About Rheumatoid Factor (RA) Test - Arthritis in Kennewick
Rheumatoid factor is an antibody directed against the body's own immunoglobulin G, and it circulates in several forms, including IgM, IgA, and IgG.
The classic rheumatoid factor is an IgM antibody, but IgA and IgG rheumatoid factors have also been reported at elevated levels in people with rheumatoid arthritis. Because these different isotypes can behave differently in laboratory assays, the specific method used by a laboratory can influence what a result means.
Rheumatoid factor is not exclusive to rheumatoid arthritis. It can be detected in other autoimmune conditions, in some chronic infections, and in a proportion of healthy individuals, particularly with advancing age. A positive result therefore supports further evaluation rather than confirming a single disease.
The test is typically ordered when a person has joint symptoms that raise concern for an inflammatory arthritis. Results are considered together with markers such as anti-cyclic citrullinated peptide antibodies, inflammatory indicators, and imaging, which together help characterize the pattern of disease.
