NCT ID NCT03776474
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at levels of a specific antibody (IgG4) to cow's milk and egg in 135 children, both with and without allergies. Researchers wanted to see if these levels could help tell which children have outgrown their allergy. The study involved a single blood draw and did not test any new treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this research could help doctors better understand which children have outgrown their food allergy and which still need to avoid certain foods.
- What could go wrong
- This is an observational study, not a treatment trial. It aims to gather knowledge, not to test a new therapy, so there is no direct benefit for participants.
