What this test is
The rheumatoid factor test measures the level of an antibody that attacks the body's own tissues. It is most commonly used to help evaluate rheumatoid arthritis, but it is not a definitive test on its own.
What it measures
- Rheumatoid factor (RF) — Overall level of the autoantibody, often reported as a titer or units per milliliter.
- RF IgM — The most common type of rheumatoid factor measured.
- RF IgA — Another type that may be elevated in some people with rheumatoid arthritis.
- RF IgG — A less common type that can also be present in rheumatoid arthritis.
What the test involves
The test requires a standard blood draw from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test when someone has joint pain, swelling, or stiffness that could be due to rheumatoid arthritis. It is also sometimes used to monitor the activity of known rheumatoid arthritis or to help distinguish it from other types of arthritis.
Preparation
No special preparation is usually needed, but you should follow the specific instructions provided by the collection lab. This may include fasting or avoiding certain medications, depending on the lab's protocol.
How results are reported
Results are typically reported as a number or a titer, along with a reference range that indicates what is considered normal. Reference ranges can vary significantly between laboratories, so your result should always be interpreted in the context of the lab that performed the test.

FAQ
Frequently asked questions
Can a positive rheumatoid factor test mean I definitely have rheumatoid arthritis?
No, a positive result does not confirm rheumatoid arthritis on its own. Many people with the condition test positive, but some do not, and the factor can also be found in other conditions or even in healthy individuals. Your clinician will consider your symptoms, physical exam, and other tests before making a diagnosis.
What if my rheumatoid factor test is negative but I still have joint pain?
A negative result does not rule out rheumatoid arthritis. Some people with the condition do not have detectable levels of rheumatoid factor, which is sometimes called seronegative rheumatoid arthritis. Your clinician may order other tests or rely on your symptoms to make a diagnosis.
Are there other reasons my rheumatoid factor might be high?
Yes, elevated levels can occur in other autoimmune diseases, chronic infections, and some liver or lung conditions. It can also be temporarily elevated in healthy people, especially as they get older. Your clinician will interpret the result along with your medical history and other findings.
How long does it take to get rheumatoid factor test results?
Results are typically available within one to three business days, but this can vary by laboratory. Your clinician's office will inform you when your results are ready and discuss what they mean for you.
