EoE Food Test Pilot Study

Functional T cell assay(s) will be performed on research subjects' peripheral blood using four foods known to commonly cause Eosinophilic esophagitis - milk, soy, egg, and wheat. Response magnitude to foods in vitro will influence whether a subject's physician chooses to recommend the subject AVOID the food or continue to CONSUME the food. Disease response to the diet changes will be evaluated in standard-of-care follow up endoscopy.
