pH Probe or Bravo Study

A pH Probe or Bravo Study is used to evaluate acid levels in the upper gastrointestinal tract and is typically ordered when a diagnosis of acid reflux is suspected.

This is an endoscopic procedure, in which a plastic coated wire with two sensors on it is inserted through the nose and into the esophagus. A tiny box is attached to the end of the wire, and this device will record acid levels during certain activities such as eating and sleeping for the next twenty-four hours. We ask that you keep a log of your child's activities during this time and return the device to the Center the following day.

A gastroenterologist will use the information recorded on the device to evaluate acid levels in your child's gastrointestinal tract.
