"THANKFUL! I thought I was giving my son one of the healthiest foods (eggs) for a growing boy. I was so thankful to have found out he was reacting to them when I did. If we hadn't done the test, I'm sure he would be getting eggs most mornings. I hope in eliminating them, we have reduced a temporary burden on his body."
