Can you have rheumatoid arthritis with negative rheumatoid factor?
If you have negative rheumatoid factor and negative anti-CCP and are diagnosed with rheumatoid arthritis, it is called seronegative RA. Occasionally, seronegative RA patients may develop antibodies and become seropositive at a later date — but this does not occur in most cases.
Can you have RA with a negative ANA test?
When the results show negative for both anti-CCP and RF, but the person still exhibits multiple signs and symptoms of rheumatoid arthritis, this is a good indication of seronegative rheumatoid arthritis. “Seronegative” simply means the person does not have the same antibodies that a person who is “seropositive” has.
What does seronegative mean for RA?
Being seronegative for RA means that a blood test doesn’t find certain antibodies your body typically makes when you have the condition. So if you are seronegative for them, an RA diagnosis would have to be based on symptoms and other things.
Is seronegative arthritis the same as rheumatoid arthritis?
There are two main types of rheumatoid arthritis (RA) in adults: seropositive and seronegative. Both have the same symptoms — joint pain, morning stiffness, fatigue, fever, low appetite — but the primary difference is in the bloodwork.

Is a rheumatoid factor of 15 high?
What are the normal ranges for rheumatoid factor? The “normal” range (or negative test result) for rheumatoid factor is less than 14 IU/ml. Any result with values 14 IU/ml or above is considered abnormally high, elevated, or positive.
How do you permanently treat rheumatoid arthritis?
There is no cure for rheumatoid arthritis. But clinical studies indicate that remission of symptoms is more likely when treatment begins early with medications known as disease-modifying antirheumatic drugs (DMARDs).
