Positive Rheumatoid Factor

It's possible that you have rheumatoid arthritis (RA), but when symptoms are present for less than six weeks, it is difficult to be sure, even with a positive RF result. That's because the joint symptoms and positive rheumatoid factor could be due to a virus that the body will fight off in short order--and then, all of your symptoms should go away. It's also possible you have a condition related to RA, such as lupus or Sjogren's syndrome.

Would you like more information about the rheumatoid factor and various forms of arthritis?

Yes, I'd like more information.

No, I'm all set, thanks.
