Regrettably, I'm a non-medically-literate layperson, but I wondered if you might have a friend or family member that could host your pets for a while? Perhaps that would allow you to see if your lab values might reverse and trend in a better direction? A very low-tech approach.
I must say you've done an incredible job in improving your environment. Obviously, you've put a lot of resources into the matter. I do hope you find the culprit and obtain the healing you deserve.
Good luck, friend!
p.s. Have you tried Spanish Black Radish?/www.youtube.com/user/NutritionalHealingA2/search?query=mold
See the video titled "Better Than Bleach! Kill Mold/Yeast in Your Body in 3 Simple Phases."
(I'd argue that few things are "simple," when it comes to illness.)
