If we suspect that your child has gastroesophageal reflux disease, or GERD, which occurs when acidic stomach content flows back into the esophagus, we may test acid levels over a period of 12 to 24 hours with an esophageal pH monitor.


We will guide a tube down your child’s nostril and into the esophagus to the point where it meets the stomach. A sensor at the end of the tube measures pH, or acidity. A monitor will record pH levels while your child engages in normal activity for up to 24 hours. The test will help us determine whether your child needs treatment for GERD.
