Ambulatory PH- Impedence Study

Your doctor may recommend Ambulatory Esophageal Reflux Testing (pH-Z monitoring).  This is a catheter-based test using a combination of pH and impedance sensors for the identification of both acid and non-acid reflux (that may be contributing to PPI Refractory Reflux Disease). It can evaluate the number of reflux events, the acid content of each event and how long each event lasted. This enables your physician to improve management of Gastroesophageal Reflux Disease (GERD) and develop the best care plan.
