Rheumatoid Factor (RA Test) Quantitative: A blood test that measures the concentration of rheumatoid factor (RF) antibodies in the bloodstream, providing a quantitative assessment of autoimmune activity associated with rheumatoid arthritis (RA) and other conditions.
Purpose: This test is primarily used to diagnose rheumatoid arthritis, assess disease severity, and monitor treatment response over time. It can help differentiate RA from other types of arthritis and autoimmune disorders.
Result Interpretation: The quantitative results are expressed in international units per milliliter (IU/mL). Higher levels of RF can indicate more active disease, while lower levels may suggest improvement or remission.
Clinical Significance: Elevated RF levels are commonly associated with rheumatoid arthritis, but they can also be present in other autoimmune diseases, infections, and some chronic conditions, making the test results part of a broader diagnostic picture.
Limitations: A positive RF test does not confirm rheumatoid arthritis, as RF can be elevated in healthy individuals and various other illnesses. Conversely, some patients with RA may have low or undetectable RF levels.
Follow-Up: The quantitative measurement helps healthcare providers track changes in RF levels over time, guiding treatment decisions and evaluating the effectiveness of therapies in managing rheumatoid arthritis.
