Overview
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.[1]
- Indications of ambulatory reflux monitoring include the following:[2]
- 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)
