Esophageal pH (acid) Monitoring

Male doctor with mature patient


UT Health San Antonio's gastroenterology practice specializes in expert diagnosis and treatments for a wide range of conditions, including acid reflux.

The esophageal pH system is an outpatient procedure to help your physician determine if you have acid reflux. Often performed when symptoms do not subside with the use of medication, this test typically lasts 24 to 48 hours in order to properly measure acidity levels in the esophagus.
