NCT ID NCT03776474

First seen Sep 30, 2025 · Last updated Jun 16, 2026 · Updated 34 times

Summary

This study looked at blood levels of certain immune markers (IgG4) in children with and without milk or egg allergies. Researchers compared these levels in allergic children, non-allergic children, and those who had outgrown their allergy. The goal was to better understand how tolerance to these foods develops, not to test a new treatment.
