Yes I know the test are often wrong. I was lucky 10 years ago. to get a Positive with Quest. I can not afford to pay out of pocket money for Igenex at this time. I do have the kits though. He complains about some things hurting, and has ADHD he has been on meds for that since he was 3. Also has trouble with reading in school. We start 4th grade this year. I have to sya he was awful in school up in till last year( it was the best year we had since he was 3)
