Positive Rheumatoid Factor

Excellent. There's a good chance that your positive RF is a false-positive, meaning that it is abnormal but of no clear significance. That does happen, perhaps more often than many people (and many doctors) realize. It's simply that the test is far from perfect in identifying those with diseases such as rheumatoid arthritis and separating them out from those who are healthy.

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.
