The Minimally Invasive 1-Hr Esophageal String Test (EST) Monitors Therapeutic Changes in Mucosal Inflammation in Eosinophilic Esophagitis

Endoscopy, standard-of-care for monitoring Eosinophilic Esophagitis (EoE), assesses mucosal inflammation. The Esophageal String Test (EST®), a minimally invasive swallowed capsule and immunoassays, quantifies EoE inflammation. We determined whether the EST/EoEScore can monitor disease in patients undergoing treatment.
