I have had pain diagnosed as seronegative RA for 15+ years, have taken methotrexate, Lyrica for fibromyalgia, and host of other NSAID drugs. Today my Dr. ran a CYCLIC CITRULLINATED PEPTIDE AB IGG test and results showed < 15 on a standard range of <20 being negative. So, I guess my question is with both of these RA lab tests not indicating RA, could I still in fact have Rheumatoid arthritis....and if not??
Any advice/help appreciated!
