Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Rheumatoid Factor
Rheumatoid Factor (RF) is an autoantibody commonly associated with rheumatoid arthritis and other autoimmune conditions. Testing RF provides valuable insight into your immune health and can help identify potential autoimmune activity early.
What It Measures
This test measures the level of rheumatoid factor antibodies in your blood. RF antibodies mistakenly target healthy tissue, which can contribute to inflammation and joint damage in autoimmune conditions.
Why It Matters
Rheumatoid factor testing can help support the diagnosis of rheumatoid arthritis and other autoimmune conditions such as Sjogren's syndrome. However, RF can also be present in healthy individuals or those with chronic infections, so results should always be interpreted alongside clinical symptoms and other tests.
When to Test
Testing may be recommended when you experience joint pain, stiffness, or swelling, especially in the hands and feet. It is also part of routine autoimmune screening when symptoms suggest a systemic condition. Consult a healthcare professional for interpretation of results.

Lifestyle Tips
An anti-inflammatory diet rich in omega-3 fatty acids, fruits, and vegetables may support joint health. Regular low-impact exercise such as swimming or walking can help maintain joint flexibility. Stress management techniques and adequate rest are also associated with reduced inflammation.
