I have searched the web trying to find out ranges that rheumatoid factor may show up as on lab results. I understand that <20 is considered normal, but other than >20, what might be considered as a low high, medium high, or super high? What might be the top most number that the factor can be elevated to?? When might a practitioner consider a referral to a rheumatologist, based on an elevated lab result?
Thank you,
