The short explanation
A positive RA factor on its own does not mean you have rheumatoid arthritis. Rheumatoid factor is an antibody that is found in many people with rheumatoid arthritis, but it is also found in some healthy people, especially older adults, and in other conditions such as infections, liver disease and other autoimmune conditions. Rheumatoid arthritis is diagnosed from a combination of symptoms, examination findings and tests. Without joint pain, swelling or stiffness, a positive RA factor is usually only something to keep in mind, not a diagnosis.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Doctors sometimes check another antibody, called anti-CCP, which is more specific for rheumatoid arthritis, along with inflammation markers, if there is reason to.
- Full body checkup packages often include tests that are not needed without symptoms, and a borderline or weakly positive result can cause worry without changing anything.
- If you later develop joint pain, swelling or long morning stiffness, mention this result to your doctor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell what your result means for you. That depends on the actual value, your health and your doctor's assessment.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How strongly positive is my RA factor?
- Does it need any further test, such as anti-CCP?
- What symptoms should I watch for?
- Do I need to repeat the test?
