My son just got tested for food allergies through the elisa food allergy igg testing. He had many "class 3s:", which is the highest class the test gives. I especially had really high scores to brewers yeast (.8 out of 1). Has anyone else had these type of scores with their kids, and if so, what did you do from here? I hate to put him on the VERY restrictive diet if there are doubts out there.
