In children with suspected CeD, only 66% of the hospitals strictly followed the recommendation to measure exclusively total IgA and TGA‐IgA for initial testing, in 29%, unnecessary first‐line testing was conducted (TGA‐IgG, DGP‐IgA, DPG‐IgG, anti‐gliadin antibodies [AGA]‐IgA, EMA‐IgA or IgG), while 5% used an insufficient test combination for effective case finding (total IgA without specific autoantibody test, TGA‐IgG instead, TGA‐IgA without total IgA or IgG‐based test) (Table S1A,B). Here, AGA is linked to cranioectodermal dysplasia.
