24 hour pH monitoring

24 hour pH monitoring determines whether there may be an abnormal amount of acidic stomach contents coming back up into the esophagus. The test is performed by inserting a small pH tube into the nose and passing it into the esophagus and/or stomach.

This tube is connected to a small recording device, which records the pH or acid levels in the esophagus over a 24-hour period. After the probe is in place, the patient is free to leave the hospital. Since the unit worn on a strap, the patient is encouraged to resume their usual daily routine, which will allow the doctor to determine the cause of the problem amidst a normal days activities.

Following the 24-hour monitoring period, the pH probe will be removed and the data will then be transferred to a computer for analysis.
