A Study of Detergents in the Pathogenesis of Eosinophilic Esophagitis

Non-invasive, FDA-registered sampling method to evaluate eosinophilic inflammation in the esophagus. The EST is performed by having an individual swallow a capsule attached to a string which captures secretions from the esophagus. The end of the string is taped to the cheek and the capsule is swallowed with water. After 1 hour, the EST will be removed, and the string will be processed for laboratory analysis.
