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.
