No draw fees, no physician fees, no surprise bills. Results usually in 1β2 business days, in your secure online account.

Understanding Your Results
A positive RF with matching symptoms supports rheumatoid arthritis but isn't specific (it's positive in some healthy people and other conditions); CCP is more specific, so the two are read together. Review with a clinician.
