Summary

This study looked at blood levels of a specific immune marker (IgG4) for cow's milk and egg in 135 children, both with and without allergies. The goal was to understand how these levels change with age and whether they can show if a child has outgrown their allergy. Researchers also compared these markers to standard allergy tests to better predict tolerance.
