24 Hour Esophageal Impedance PH Test

The esophageal pH test is an outpatient procedure performed to measure the pH or amount of acid that flows into the esophagus from the stomach during a 24-hour period.

It measures the rate at which liquids and gases pass through your esophagus. When these results are compared with your manometry findings, your doctor will be able to assess how effectively your esophageal contractions are moving substances through your esophagus into your stomach.

After your test, your throat may feel a little sore for a day or so. Sucking on lozenges or hard candy may be soothing. Later on, at your next doctor’s appointment, you should receive the results of your esophageal pH test. After applying a numbing agent to the inside of your nose, the doctor will ask you to remain seated. Then a narrow, flexible tube will be passed through your nose, through your esophagus, and into your stomach. Before inserting the tube, your gastroenterologist may administer a mild sedative to help you relax. The doctor may also spray your throat with an analgesic spray to make the procedure more comfortable for you.

There are no alternatives for obtaining the information that esophageal pH monitoring provides. Nevertheless, the presence of esophagitis visually at the time of endoscopy strongly suggests the presence of acidic reflux among patients who don’t have other likely causes of esophageal pain This may obviate the need to do a pH monitoring study. If your doctor recommends an endoscopy, she will have you set up a time to do the procedure, usually in the endoscopy suite at the hospital or in a free-standing endoscopy clinic. She will advise you that the procedure can be a little uncomfortable, but is usually tolerated quite well.

A few people have GERD that doesn’t respond to treatment. Or they may have other concerning symptoms, such as weight loss , difficulty swallowing, anemia , or black stools. If you’re one of them, you may need any of the following tests. Esophageal pH monitoring is a test used to evaluate for gastroesophageal reflux disease and to determine the effectiveness of medications that prevent acid reflux. This test measures the amount of acid refluxing or backing up from the stomach into the esophagus (food pipe).

This test may be performed in combination with an endoscopy of your upper gastrointestinal (GI) tract. During an endoscopy, your doctor inserts a flexible scope with attached camera into your esophagus, to look for causes of GERD. Either way, you will be keeping a record of any suspected acid reflux issues, and other symptoms, such as coughing and wheezing. This can help the doctor determine if acid reflux is related to unexplained asthma or other respiratory symptoms. Depending on what the EGD shows, your doctor may decide to perform a biopsy during the procedure. If this is the case, your gastroenterologist will pass a tiny surgical instrument through the scope to remove a small piece of the lining in the esophagus. The tissue sample will then be sent to a pathology lab for analysis. There it will be assessed to see if there is an underlying disease such as esophageal cancer.
