About this test

What Are Rheumatoid Factors?
Rheumatoid factors (RF) are a diverse group of autoantibodies that target the Fc region of IgG antibodies. These autoantibodies are commonly associated with autoimmune activity within the body.

Diagnostic Role in Rheumatoid Arthritis
Rheumatoid factors are a key marker used in the diagnosis of rheumatoid arthritis, an autoimmune condition that primarily affects the joints, leading to pain, stiffness, and swelling. Their presence supports early detection and management of the disease.

Presence in Other Conditions
While most commonly linked to rheumatoid arthritis, rheumatoid factors may also be detected in other inflammatory rheumatic diseases as well as certain non-rheumatic conditions, such as chronic infections and liver disorders.
