Is Gluten Free Wheat flour safe for Celiacs? https://bread-free.com/products/

Her IgA was normal at 89. TTG IgA Ab was less than 1.

Thanks @trents I'll keep that in mind.

One thing to be aware of is that reactions to gluten can sometimes be more severe after having been gluten free for a significant period of time. Something to think about in connection with a gluten challenge.

Hi @trents Thanks for your reply and the clarification on terminology—most appreciated. My GP has referred us to a Paediatric Gastroenterologist, and we're waiting for an appointment. She mentioned they might want to do an endoscopy or run further testing. But that often with children they try to avoid scoping them.  She also said it could take months to get an appointment, which is why she recommended starting a gluten-free diet immediately to see if there's any improvement in his symptoms, growth, and blood tests. I have an appointment in 5 weeks with the Paediatrician (who ordered all the tests)—not the Gastroenterologist. I expect the Paediatrician will also recommend a Gastroenterologist referral for further testing and diagnosis. I understand the reasons for confirming with biopsies. I'm just eager to help him feel better and I don't want to keep him eating gluten for months while waiting for a specialist when it's clearly affecting him. I really appreciate your input on this, especially your thoughts about this pointing to celiac rather than NCGS. Intuitively, it feels that way—he's always been incredibly healthy and strong, but he's suddenly wasting away. We're in Australia, so I'm not sure about benefits, etc. and needing a formal diagnosis. I’ll have to investigate.  If necessary to do a gluten challenge down the track for confirmation I'm happy to cross that bridge when I come to it. Thanks so much for your advice!
