This is an autoantibody, most likely an IgM class that attacks the Fc region of an IgG antibody. “Research initiated by Cecil, Nichols, and Stainsby (1931), Waaler (1940), and Rose, Ragan, Pearce, and Lipman (1949) on the agglutinating activity of serum from patients with rheumatoid arthritis led to the discovery of a serum factor, now regarded as characteristic of rheumatoid arthritis, and therefore designated “rheumatoid factor”” (Wholer, Muller & Hofmann, 1960). The biomarker can be developed in healthy individuals during acute infectious diseases so the presence of the factor can be misleading. Multiple tests to confirm a high titer of the autoantibody are usually done after the infection has passed to confirm a rheumatoid arthritis diagnosis. The presence can be less in the beginning stages of the disease then rise after an individual has had the illness for some time. Therefore, rheumatoid factor is not a cause of the disease but an indication that is useful in making a medical identification of a problem. It is a way to recognize the disease beyond just basic symptoms of paint, joint stiffness and
