Healthy volunteers needed to set new standards for reflux testing
NCT ID NCT05180253
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to collect normal measurements from the esophagus and stomach in 40 healthy adults aged 18-85. Participants will undergo two quick, FDA-approved tests during a standard upper endoscopy to measure muscle function and tissue health. The data will help doctors better diagnose reflux and swallowing problems in the future.
