The AGA test is now considered outdated. It has been replaced by the DGP test which is considered more accurate. Still, it is a positive and I can understand your frustration. Here is a study about
a positive AGA test, though not common, can catch a CD diagnosis.
All celiac tests require you to be on a gluten diet. Was the child on a gluten diet? What did the GI recommend? Did he suggest a gene test? This test is used to help rule out celiac disease. Did he suggest re-testing in six months? Did he suggest an endoscopy to obtain intestinal biopsies (and still considered the gold standard for diagnosing celiac disease).
Susie is correct. Another professional opinion by a celiac-savvy GI may be in order. Celiac disease can develop at any age. If there is a first degree relative who has CD, your child should be screened every few years. To learn more visit the University of Chicago's celiac website which is well-written or the Celiac Disease Foundation.
