Diagnostic Value of Anti‐deamidated Gliadin Peptide IgG Antibodies for Celiac Disease in Children and IgA‐deficient Patients

Abstract

The diagnostic performance of anti-dGp depends on the antibody isotype and on the age at CD diagnosis, anti-dGp IgG being a serological marker at least as useful as anti-tTG IgA for detecting CD in children ages 7 years or younger. Our data also indicate that anti-dGp IgG can improve the diagnosis of IgA-deficient patients.
