Noninvasive biomarkers identify eosinophilic esophagitis: A prospective longitudinal study in children

Esophageal histology is critical for diagnosis and surveillance of disease activity in eosinophilic esophagitis (EoE). A validated noninvasive biomarker has not been identified. We aimed to determine the utility of blood and urine eosinophil‐associated proteins to diagnose EoE and predict esophageal eosinophilia.
