NCT ID NCT04239131
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 96 adults with house dust mite allergy to see if they also react to edible insects like crickets or mealworms. Participants had skin prick tests and their allergy history was reviewed. The goal was to understand patterns of insect sensitization, especially in those already allergic to seafood.
