wille25 posted a topic in Celiac Disease - Parents of Kids or Babies With Celiac DiseaseMy son just had his one year well baby and has fallen off the growth charts and now has a trend for a downward spike for the last three appts. We went and had blood work done and his Gliadin AB IgG level is 17. No our ped wants us to go to a GI specialist. Does anyone know what the next step is and what the GI specialist will test for and how invasive the tests are? Anything would be helpful we are kind of at a confused stand still and I haven't been able to get a straight answer. Thank you so much.
