What is the Rheumatoid factor?

Does it ever change with flare ups? And, I understand the normal Rheumatoid factor is 14. My Rheumatoid factor reads 31, but I'm reading that some people have a factor of 90 and higher.

  1. Hi there "greatestmother" Thank you for reaching out. RA can effect each person in different ways. While some with RA may have an elevated Rheumatoid Factor others may have a negative factor. Rheumatoid Factor is one of several components in diagnosing RA. It can fluctuate and doesn't always match with current symptoms, which is why it's only one piece of assessing RA progression. In addition to speaking with your doctor, this article may be helpful to you: https://rheumatoidarthritis.net/living/what-ra-factor-diagnosis-mean/. Kelly, Rheumatoidarthritis.net Team Member
