Bravo pH Probe Test

The Bravo pH probe is a test that records the pH or acid content within your esophagus for 48 hours. 

You will be asked not to drink or eat anything for eight hours before the test. For 24 hours before the test stop the following medication: Zantac, Tagamet, Pepcid, Axid, Reglan(metoclopromide), Bethanechol (urecholine), Lomotil(diaphenoxylate) or any antacid. Prilosec (omeprazole), Protonix, Aciphex, Protonix, or Prevacid must be stopped four days prior to the test unless your doctor specifies otherwise. Your doctor may also want you to lower the head of your bed if you have it raised.

The Bravo capsule is placed during an endoscopy. Once your physician has examined your stomach and esophagus, a miniature pH capsule (about the size of a gelcap) is attached to the esophagus. The capsule contains a radio-transmitter that will transmit the data to a pager-sized receiver which is worn on your waistband or belt. 

You will be asked to keep a diary during the 48 hours of testing. Please write down any activities you may do such as sitting down, bending over, lying down, eating, or exercising. You will also be instructed to press the appropriate button on the recorder for these activities. Bedtime and wake-up times should also be written in your diary. If you experience any symptoms of indigestion, burning, chest pain, abdominal pain, or pressure you need to press the "event" button on the recorder and write it down in your diary. 

Data continues to be recorded as long as the capsule and receiver are within 9 feet of each other. You can bathe and sleep as usual. Be sure to place the receiver on the cabinet in the bathroom while bathing or the nightstand by the bed while sleeping. 

You may feel a vague sensation that "something" is in your esophagus. It should not be painful. You may feel the capsule when you eat or when food passes by the capsule. If you experience this, chewing food carefully and drinking liquids may minimize this sensation. 

After 48 hours, the Bravo receiver needs to be returned to the Digestive Disease Center. The test data is uploaded to a computer and analyzed by your physician. 

Several days after the test the capsule naturally falls off the wall of the esophagus and passes through your digestive tract and is eliminated from the body.

You cannot undergo an MRI study for 30 days after the Bravo procedure.
