Well the Ref range i used (VA lab) is 0-20 U/mL. I was 26.7. So i would get on it right away. Get an anti-CCP test also.
If that is positive, then you do have RA. CCP range was 0-5 U/mL i was 8.6. Ive seen some real high #'s in this forum and others. Some people manage with meds or Biologics and go into remission and can do stuff. So far for me, im in pain, but not to the point of being unable to do the basic everyday stuff. Walking my big dog is getting harder, i stiffen up in the back and the walks are shorter. Good Luck and get started with Rheumatolgist as im about to do.
