HI Wendy,
If you haven’t see a rheumatologist yet, it would be a good idea to do so. There are many types of arthritis and some cannot be diagnosed by a blood test. There are many pain syndromes that can mimic arthritis, too, like fibromyalgia and TMJ syndrome (pain in the jaw). Plus, there is another blood test that should be checked before RA is fully ruled out. Good luck !!
