Interestingly, I just ordered the organic acids and metal urine test from Great Plains Laboratory and you're sending me the link as well. :)
Those tests should clear thing out a little more. They didn't give me the price though so I'll have to call them tomorrow.
I was taking Candicid Forte as my doctor told me but that had aggravated my GERD so much that my voice is hoarse now and I see blood in my saliva sometimes so I'm off anything that is not alkaline. Won't be able to take caprylic acid until I get the reflux under control.
