Hi everyone -
Hi Allison, and welcome back. Sorry you're in a bad flare. Yes, I've had the CCP (or anti-CCP as it's sometimes called), but like you said, it was during the diagnosis stage. It is a bit strange that they want to do it now, but ask the doctor why and maybe we'll all learn something.
For more info on the test, you can check out http://www.labtestsonline.org/understanding/analytes/ccp/glance.html. I just read the overview and it can sometimes be used to evaluate prognosis...maybe that's what the new doc is doing?
