Diagnostic screening for subclinical celiac disease using a rapid test in children aged 2-4.

Background: Our aim is to study the prevalence of subclinical celiac disease (CD) and analyze the diagnostic yield of a new rapid test in children aged 2-4.

Methods: We carried out a cross-sectional study in a sample population of children aged 2-4 from the same metropolitan area. We recruited apparently healthy subjects, and collected clinical, anthropometric, analytical, and serological variables.
