A blood factor present in rheumatoid arthritis and various other infectious diseases.
Antibodies raised by the body against immunoglobulins. They are present in roughly 80% of patients with rheumatoid arthritis and in many patients with other rheumatological and infectious illnesses.

An autoantibody detected in the serum of numerous individuals who are either afflicted by rheumatoid arthritis or prone to developing it.
A particular autoantibody, which is a protein created by the immune system to target the body’s own cells, attaches itself to naturally existing immunoglobulin G. This is another antibody that, in this context, has actually initiated the immune response. When these two combine, they form an immune complex that can accumulate in the joints, leading to rheumatoid arthritis. The majority of individuals with rheumatoid arthritis have this rheumatoid factor present in their blood.
