RHEUMATOID FACTOR (RF)

The rheumatoid factor (RF) test measures the level of RF antibodies in the blood. RF antibodies are often present in individuals with rheumatoid arthritis and other autoimmune diseases. Elevated RF levels indicate an autoimmune response, suggesting conditions such as rheumatoid arthritis, Sjgren’s syndrome, and systemic lupus erythematosus. The RF test is used to diagnose and monitor autoimmune diseases, guide treatment decisions, and assess disease activity. It provides valuable information for managing autoimmune conditions, ensuring timely intervention, and improving patient outcomes.
