Question
I have Rheumatoid factor of 440. I realize this is high. But what is the severity of my RA with a factor this high? My ccp is 33 and SED Rate is 25. I am 43 and just discovered this 2 weeks ago, due to foot and shoulder pain. Could you please give me some guidance.
Answer
The severity of your arthritis does not depend on the rheumatoid factor test alone. In general, studies show that patients with high rheumatoid factor test have more severe disease, but the correlation is not always true for the individual patient. I think the high test value means that you should be followed closely for prompt and appropriate treatment.
