Rheumatoid factors (RFs) are IgM-type antibodies that interact with assay antibodies at the Fc area. RFs are present in serum from more than 70% of patients with rheumatoid arthritis.

Can RA factor be reduced?
Exercise. In addition to performing targeted stretches, some dynamic, low-stress forms of exercise can benefit people living with RA. Activities such as swimming or cycling can strengthen the muscles around the affected joints. This can help reduce the overall impact on the joints and slow the progression of RA.
