I'm very familiar w the Tahoma Clinic/Dr. Wright - an esteemed "iodine doc", actually. It sounds like he used either Dr's. Data or Genova. My experience and opinion is these labs too commonly produce inaccurate and often false negative results. Did you actually see a copy of the results and read ZERO for C. albicans? It's simply absurd.
What symptoms suggest to you Candida overgrowth? Did they or have you considered b hominis, d fragilis, etc.?
The bottom line, whatever the case/cause, is that if your issues are microbial in nature AND limited to the GI - you and only you should be able to get dysbiosis of such a level under control. And you are in the right place, probably doing the right things. Have you made any progress, Marci? I know you've been around a while.
