What tests are used to diagnose acid reflux disease?

ANSWER

If medications or lifestyle changes don't help, or if you have frequent or severe symptoms, your doctor may order tests to confirm a diagnosis and check for other problems. You may need one or more tests, such as these:

  • A barium swallow (esophagram) can check for ulcers or a narrowing of the esophagus. You first swallow a solution to help structures show up on an X-ray.
  • Esophageal manometry can check the function and movement of the esophagus and lower esophageal sphincter.
  • pH monitoring can check for acid in your esophagus. The doctor inserts a device into your esophagus and leaves it in place for 1 to 2 days to measure the amount of acid in your esophagus.
  • Endoscopy can check for problems in your esophagus or stomach. This test involves inserting a long, flexible, lighted tube with a camera down your throat. First, the doctor will spray the back of your throat with anesthetic and give you a sedative to make you more comfortable.
  • A biopsy may be taken during endoscopy to check samples of tissue under a microscope for infection or abnormalities.
