Most of my (blood) labs were negative in the beginning and even now (after diagnosis) they are borderline or up and down. My biopsies were positive as well as some scans and some other tests. My rheumy saw everything that was happening to me and did the wait and see thing. The longer he waited the more stuff that happened to me, so my advice is stick with you rheumy and try to be patient.. I know....I mean I really know how hard that is to do but it will present itself eventually. In the meantime see that your pain is treated and you do the best you can to feel better right now.
