Summary

This study looked at 145 people who had an allergic or non-allergic reaction during surgery. Researchers wanted to find out which signs, like skin changes or heart rate, could tell the difference between a true allergy and a non-allergic reaction. The goal is to help doctors treat dangerous allergic reactions faster and more accurately.
