Hello, and welcome to the forum.
I can’t help you much with the test accuracy as I never sought the help of a physician of any kind when I had the infestation so never took a test.
Yes it looks like you started a good case of die-off when you went directly on a green vegetables diet and started taking probiotics all at the same time. You can’t do this unless you want to become a lot sicker than you have been; but then, you know that now. I would agree that it sounds a lot like your problem is a Candida overgrowth.
Read the protocol on the forum as this is what most of the members are doing for their treatment.
Let us know if you have other questions after reading the protocol.
