What tests help diagnose gastroesophageal reflux disease (GERD)?
ANSWER
If your doctor isn't sure you have GERD, she may do a few tests, including:
- X-ray
- Endoscopy. This looks at your esophagus with a small flexible tube with a light and camera on it.
- Ambulatory acid (pH) test. This keeps track of the amount of acid in your esophagus.
- Esophageal impedance test. It measures how things move through your esophagus.
