What is a Bravo esophageal pH test?

The Bravo pH test is used to measure the levels of acid reflux in the esophagus. This information may be helpful in some patients where acid reflux is in question. It can provide information to a doctor about when stomach acid enters the esophagus. It can also help them determine the best treatment plan if the patient is experiencing symptoms of acid reflux, such as heartburn or a sore throat. The test measures the pH levels in the esophagus. The pH levels of a substance determine whether or not the substance is basic or acidic. When the acid of the stomach enters the esophagus, it decreases the pH level and can damage its lining. Patients will undergo this test if their doctor believes that they might have GERD, also known as gastroesophageal reflux disease. Symptoms of GERD include heartburn, chest pain, sore throat, and coughing.

What is the Bravo esophageal pH test like?

To prepare for the test, a patient may be required to stop taking proton pump inhibitors for seven days prior. They will also be required to stop taking H2 blockers for two days prior and antacids for six hours before the test. In addition, they will need to fast for four to six hours before the procedure.

The Bravo pH monitoring test system contains a pH sensing wireless capsule, a recorder, and a software system. The patient will have the wireless capsule placed during an upper endoscopy,
into the esophageal tissue. The patient will wear a recorder to capture data for 48 hours. After the recordings are completed, a doctor will then be able to view the data and develop a treatment plan that best suits the patient. The capsule that is placed is the size of a large pill and the recorder can be worn on a belt or waistband. The patient will use the buttons on the recorder to record symptoms of GERD. They will also be asked to write down the symptoms they experience when they start and stop eating or drinking and when they lie down and get up. Patients can resume taking any medications after the study is complete. The capsule will detach and pass through the digestive tract within seven to ten days.

Patients who have symptoms of GERD may want to talk to their doctor about a Bravo Esophageal pH Test. Treatment for GERD can help the patient avoid other health complications.
