Can the diagnosis of celiac disease be based on serologic tests alone?

Authors’ conclusions: in a prospective study, we validated two procedures based on the determination of anti-glutaminase and anti-gliadin-deaminated antibodies for the identification of pediatric patients with or without celiac disease, without biopsy.

Reviewers’ commentary: although serological determinations are useful for the diagnosis of celiac disease and can allow diagnosis without duodenal biopsy, it seems reasonable to continue with the current recommendations, especially in groups of patients with low risk of disease.
