What is Esophageal pH Monitoring?

Esophageal pH monitoring is a test to diagnose the abnormal reflux of acidic stomach contents back into the esophagus. This condition, known as GERD, is a common cause of heartburn, indigestion and sometimes unusual symptoms such as chest pain, cough, sore throat or laryngitis.

During the procedure, the acid level (pH) in the esophagus is measured over 24-48 hours by either a probe attached to the lining of the esophagus during an upper endoscopy procedure or a long, thin tube inserted through the nose.

The information is transmitted to a recording device worn by the patient during the procedure. The patient is also asked to record symptoms during the test. The physician analyzing the data can determine if the patients symptoms are related to GERD.
