Summary

This study tests a new, less invasive device called the Esophageal String Test (EST) to diagnose and monitor a rare condition called eosinophilic esophagitis (EoE). Instead of using a scope with a biopsy, patients swallow a small string that collects samples from the esophagus. The goal is to see if the string test can accurately measure inflammation and help doctors track treatment without needing repeated endoscopies. About 440 people with suspected or known EoE are taking part.
