Summary

This study looks at what happens in the body right after a tick bite. Researchers want to learn why some people develop a food allergy to red meat, called alpha-gal syndrome. About 100 adults who have been bitten by a tick will donate blood and their tick for testing. The goal is to find early signs that predict who will get the allergy.
