Eosinophilic Esophagitis (EoE)-Causal Food Assay

The goal of this study is to evaluate the effectiveness of a new blood test for Eosinophilic Esophagitis (EoE). Eligible participants include patients undergoing their first upper endoscopy for evaluation of EoE, or who have already been diagnosed with EoE, but whose food sensitivities are currently unknown. The findings of this study will contribute to the development of clinical diagnostic tools (ie. blood tests for food allergies) that will decrease the time needed to identify food sensitivities, and subsequently reduce the time to symptom resolution for newly diagnosed patients with EoE.
