I'm in the exact same spot as you powertool. Getting ready to send out more poop and swabs for parasite and bacteria testing. And talking to my doctor Tuesday about chelation.
I haveheard of Dr Buttar and had heard he did heal his own son. Did he use the transdermal on his son or IV ?
Another autism doc , Dr. Andrew Levinson reports chelation really helping iwth gut problems in the kids, including severe problems. He reports not working on the gut too long.
Where are you having your testing done ? I'm thinking rectal swab to the parasitology centre in arizona and also the poop test done by diagnos-tech.
