NCT ID NCT00702533
First seen Jun 27, 2026 · Last updated Aug 05, 2026 · Updated 12 times
Summary
This study tests a new, less invasive way to measure stomach acid using a small wireless capsule (SmartPill) that patients swallow. It compares the capsule's accuracy to the standard method, which involves a tube placed through the nose into the stomach. The study includes healthy volunteers and people with acid-related disorders like Zollinger-Ellison syndrome and GERD.
