Rheumatoid factor (RF) is an antibody produced by the immune system, often associated with autoimmune conditions like rheumatoid arthritis (RA). A blood test can detect elevated levels of RF, providing valuable information for diagnosing and managing RA. However, it’s important to note that RF can be present in individuals without RA, and not everyone with RA will test positive for RF. The RF test is part of a comprehensive diagnostic approach, considering clinical symptoms, imaging studies, and other blood tests for an accurate assessment of autoimmune conditions. Positive RF results aid healthcare professionals in guiding treatment decisions and monitoring the progression of rheumatoid arthritis.
