YouCanCallMeCelia replied to bincongo's topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsIf you test an asymptomatic child can the blood test still be positive? Or do you have to wait for things to "build up" to have it show? I am waiting on my biopsy report - not even sure I have Celiac yet but I am worried about my 9 yr old who is already so constipated she has to take stool softeners daily She has been constipated pretty much since she started eating. I didn't have the blood test because I was at the gastro for reflux...he only mentioned Celiac when I said I had unexplained low iron. Now that I've done a little research I have several more symptoms that could be explained by Celiac. I just know my siblings will shrug it off and not get tested. sigh.
