Esophagus Tests

What To Think About

  • Occasionally, samples of stomach secretions may be taken during the pH monitoring test.
  • Combining multichannel intraluminal impedance testing with pH (MII-pH) can record reflux, even if it's not acidic. pH testing by itself will only record acidic reflux events.
  • Other tests may be done to help diagnose problems with the esophagus, including upper gastrointestinal (UGI) endoscopy, barium swallow, or upper gastrointestinal studies (upper GI series). For more information, see the topics Upper Gastrointestinal (UGI) Series and Upper Gastrointestinal Endoscopy.
