Monitoring Tests. In order to diagnose gastroesophageal reflux disease (GERD), a pH monitoring test is necessary to keep track of acid levels in the esophagus. This test can help assess whether acid reflux disease is present and what treatments might help.It is possible to monitor pH in the esophagus and changes in pH levels for a period of up to twelve hours. Esophageal pH monitoring tests can be performed as an outpatient procedure.ased on the description of your symptoms, the doctor will determine whether you are suffering from indigestion or whether there is a possibility that you have GERD. Detailed medical and health history records are important documents that can help illustrate the progression of a problem.
The main diagnostic tests include an endoscopic examination of the esophagus and stomach to check for inflammation or ulceration; a test to check for acid in the esophagus (this would be negative if bile reflux is the only problem), and a test to determine if gas or liquids reflux into the esophagus.
