Study of pH-impedance tests for GERD diagnosis
Part of Digestive system clinical trials.
This trial looks at how well a special test (pH-impedance) can diagnose GERD (acid reflux disease) when done correctly. It will use a new way to read the test results to see if it helps doctors classify GERD better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have had a pH-impedance test without taking acid-reducing medication (like omeprazole).
- You have not had any surgery on your esophagus or stomach.
- Your pH-impedance test must have recorded for at least 21 hours.
- You have not had a recent upper GI endoscopy showing a serious structural problem (except mild esophagitis or hiatal hernia).

This study compares two ways of placing a reflux testing probe to find which works better for women and people with a lower body mass index. You may be able to join if you have typical heartburn or regurgitation symptoms and have not had stomach or esophagus surgery.
This trial tests a new way to treat GERD (chronic acid reflux) using a tiny camera and a device that delivers a gentle heat treatment (argon plasma coagulation) to the area where the stomach meets the esophagus. It's compared to a 'sham' procedure (you won't know which you get) to see if it stops acid from backing up better than medicine alone.
This study looks at the “upward reflux” that can irritate the throat and sometimes worsen symptoms like cough or asthma. It aims to understand the mechanisms that prevent or allow throat reflux, which may lead to better ways to manage symptoms.
This study looks at how following specific diet and behavior changes affects symptoms of acid reflux (heartburn/regurgitation) in everyday life. It may help you understand what lifestyle steps improve reflux and how symptoms change over time.
This study checks whether a special test of the esophagus after meals can find the exact reason for ongoing reflux symptoms when proton pump pills (PPIs) don’t help. It may help doctors choose the right next treatment for people whose reflux symptoms keep coming back.
This study tests a new way to measure how your esophagus lining reacts to acid (called mucosal impedance) to help diagnose GERD. It's for people who still have symptoms even after taking standard medication for 8 weeks.
