Benefits of Monitoring Your RF Levels
The Rheumatoid Factor (RF) Test is a crucial screening tool used to detect the presence of Rheumatoid Factor, an autoantibody often associated with Rheumatoid Arthritis (RA) and other autoimmune disorders. Rheumatoid Factor is a protein produced by the immune system that can mistakenly attack the body’s own healthy tissues. This rapid test provides a simple, quantitative measurement of this marker, giving you a quick insight into potential inflammatory or autoimmune activity in your body. Get your results quickly from a simple finger-prick sample.
Early Detection
Detect and address raised RF levels early before disease progression.
Investigating Joint Symptoms
If you suffer from persistent joint pain, morning stiffness, or swelling in multiple joints (symmetrically), the RF test is often the first step.
Screening for Autoimmune Conditions
High levels of RF are most closely linked to Rheumatoid Arthritis, but can also be elevated in conditions like Sjögren's Syndrome, systemic lupus erythematosus (SLE), and chronic infections.
Monitoring Disease Activity
In individuals already diagnosed with RA, the RF level may be monitored (alongside CRP/ESR) to assess the level of autoimmune activity.

What Are the Symptoms of Rheumatoid Arthritis (RA)?
Rheumatoid Arthritis (RA) is a chronic inflammatory disorder that most commonly affects the lining of the joints, causing painful swelling. Unlike the wear-and-tear damage of osteoarthritis, RA affects the body systemically. Key symptoms often include:
1
Symmetrical Joint Pain
Pain and tenderness affecting the same joints on both sides of the body (e.g., both wrists or both knees).
2
Morning Stiffness
Stiffness that lasts for an hour or more after waking up, which is a classic indicator of inflammatory arthritis.
3
Swelling and Warmth
Joints become visibly swollen, warm, and tender to the touch, most commonly affecting the small joints of the hands and feet.
4
Systemic Symptoms
Fatigue, fever, and weight loss can occur, indicating systemic inflammation.

What do your RF test results mean?
Your result is reported in (IU/L). Note that a positive result alone is not diagnostic for RA; clinical assessment and correlation is essential.
| RF Level (IU/mL) | Classification | What do your results indicate? |
|---|---|---|
| Under 15 | Normal | Indicates Rheumatoid Factor (RF) is within the normal range. If you suffer from any symptoms or have concerns, see your doctor for assessment. |
| Between 15 and 40 | Elevated | Indicates elevated levels of Rheumatoid Factor which could suggest an inflammatory or autoimmune disease. See your doctor for further investigation. |
| Above 40 | High | Shows that your Rheumatoid Factor levels are high. This could be due to the presence of an inflammatory or autoimmune disease. See your doctor for further investigation. |
Please be aware that different laboratories, manufacturers, and providers may use slightly different reference ranges. The reference ranges provided on this page are for general guidance only and represent commonly accepted clinical thresholds.
This rapid blood test is designed solely as an initial screening tool for triage and is not a substitute for a full lab-based venous blood draw. The results offer quantitative insights but are for informational purposes only and should not be considered a medical diagnosis. Any abnormal or significant result must be followed up with a medical assessment with your doctor and potential confirmatory lab-based testing.

What is Rheumatoid Factor (RF)?
Rheumatoid Factor is an autoantibody, meaning it is an antibody produced by your immune system that incorrectly targets the body’s own proteins. Specifically, RF targets the Fc portion of the human IgG antibody.
Is a positive RF result always Rheumatoid Arthritis (RA)?
No. RF is not specific to RA. A positive result can occur in up to 10% of healthy individuals, especially the elderly. It is also often positive in other conditions like chronic infections, lung disease, or other connective tissue diseases. A diagnosis of RA requires clinical symptoms and often confirmation using a more specific marker like the anti-CCP antibody test.
Do I need to fast before the test?
No, fasting is not required for the RF test.
Can I have RA if my RF test is negative?
Yes. Approximately 20% to 30% of people who have a confirmed diagnosis of Rheumatoid Arthritis are “seronegative,” meaning their RF test is negative. In these cases, the diagnosis relies heavily on clinical symptoms and other biomarkers, such as CRP, ESR, and the Anti-CCP antibody test.
Is the test suitable for children?
The service is primarily for adults; therefore, we can only offer this test to those aged 18 years and over. Please consult with your GP if you are aged below 18 years old.
What is the difference between RF and Anti-CCP?
Both are used to diagnose RA. RF is common but non-specific. Anti-CCP (anti-cyclic citrullinated peptide) is a newer, highly specific marker. If both RF and Anti-CCP are positive, the diagnosis of RA is much more likely.
