You're very welcome. My heart goes out to both of you; its a scary time for you.
One thing I still wanted to share about was how easy the food testing itself turned out to be!
I don't know what state you're in (I'm in Oregon) but the testing I had done was fast (45 min.), totally painless, checked for over 180 foods, additives and combinations and I had the test results in my hand before I ever left the office.
It cost me $85 total. My insurance may or may not still cover it- they're pretty nit-picky, but regardless - the knowledge its given me is priceless.
Anyway, here's a info link about this type of testing. I'm sure it, or something similar, is offered "in your neck of the woods", if you choose to look into it.
