Hello @ellenh — Welcome to Connect. Thank you for sharing your post. It is a good thing to ask questions and learn all you can about your health condition. I don't have RA but do have polymyalgia rheumatica that is currently in remission. I found a website that may give you some additional information about the Anti-CCP Test (Anti-Cyclic Citrullinated Peptide):
@ellenh did the doctor identify any other conditions along with the anti CCP test that indicates RA? According to the anti CCP test description it is used in conjunction with several other criteria to make a diagnosis of RA. I would ask them what else makes them think RA.
