Tests and diagnosis

By Mayo Clinic Staff


Your doctor might recommend:

  • Endoscopy. A flexible tube (endoscope) that is passed down your throat allows your doctor to see the inside of the esophagus. Your doctor may remove a tissue sample (biopsy) for testing to rule out other esophageal diseases.
  • X-ray. Images of your esophagus are taken after you swallow a contrast liquid.
  • Esophageal manometry. This test measures muscle contractions in your esophagus when you swallow water
  • Esophageal pH monitoring. This test can determine if stomach acid is flowing back into your esophagus (acid reflux).
