Laboratory Findings

Ambulatory reflux monitoring

• GERD is mostly diagnosed clinically by the presenting typical symptoms which include heartburn, regurgitation, and dysphagia.
• Correlation of the GERD symptoms with confirmed acid presence by the ambulatory reflux monitoring is strongly suggestive of GERD.
• Ambulatory reflux monitoring is recommended by the American College of Gastroenterology (ACG) as the only laboratory test to determine the presence of acidic reflux in the esophagus.
• Indications of ambulatory reflux monitoring include the following:
  • GERD diagnosis if it is not confirmed
  • Determine the time of reflux occurrence
  • Refractory GERD symptoms
  • Preoperative for non-erosive disease
• Ambulatory reflux monitoring is performed in either two ways which include:
  • Telemetry capsule (48 hours monitoring)
  • Transnasal catheter (24 hours monitoring)
