Esophageal Function Testing (impedance/manometry)

When the esophagus is not functioning properly, several tests can be used to assist in providing an accurate diagnosis. Manometry is used to check the ability of the esophageal muscles for their ability to contract properly. Esophageal pH monitoring measures changes in the acidity of the esophagus, which is especially useful when evaluating heartburn or gastroesophageal reflux disease (GERD). Multichannel intraluminal impedance testing is a new technique to measure how far up the esophagus acid or alkaline from the stomach travels.
