Update

I just heard back. Our pediatrician is referring us to an infectious disease expert. This doctor is willing to do the tests, but doesn't really buy into PANDAS affecting anorexia (he thinks it has more to do with movement and tics). Anyway, at least they were willing to do the tests (ASO Titer, AntiDNA, and FreeT). If the antibody levels come back high, then I need to be armed with a bunch of research and be ready to make a case for antibiotic treatment for N.
