Experiencing symptoms like joint pain, stiffness, and swelling, suggestive of rheumatoid arthritis or related autoimmune disorders? A Rheumatoid Factor (RF) test may be recommended. This blood test detects RF antibodies, which are often elevated in autoimmune conditions like rheumatoid arthritis. Timely medical evaluation is crucial for an accurate diagnosis and appropriate management, especially when these symptoms persist or worsen. RF testing aids in identifying autoimmune disorders, enabling early intervention and improved symptom control.
