Blood test could spare kids from risky food allergy challenges
NCT ID NCT03265262
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a blood test called the basophil activation test (BAT) can accurately diagnose food allergies in children, potentially replacing the need for oral food challenges (OFCs). Researchers tested 116 children aged 0-18 who were already scheduled for an OFC. The goal was to see if BAT results match OFC results well enough to safely replace at least half of those food challenges.
