I'm scared of a misdiagnosis , either way. I want to help him, but I want to know how to help him properly. I have walked where you are walking now, and I understand your fear. I didn't want any label that wasn't right for Ryan. But I am glad to see that you are pursuing answers.
Time is of the essence.
In regards to the diet, there are 2 tests that can help you decide if you need the diet. The first is a urinary peptide test. This checks to see if there are gluten or casein peptides in your child's urine. The second test would be a simple blood test to look for IgA and IgG antibodies to gluten and casein. This would show if the child is having an immune reaction to these substances.
