A Bravo involves a miniature pH capsule, approximately the size of a gel cap, which is placed during an EGD procedure. Throughout the test period, the Bravo capsule measures the pH in the esophagus and transmits this information to a pager-sized receiver worn on your belt or waistband. You will be given a diary to write down the times when you have reflux symptoms (for example, coughing, heartburn, regurgitation), when eating or when lying down.


After the test is completed, you return the diary and the Bravo Receiver to your doctor and the information is uploaded to a computer, which provides a comprehensive report so the physician can diagnosis your condition.

Your doctor will ask you to not eat or drink after midnight. You will also be asked to stop all proton pump inhibitors (PPI) at least two weeks prior to the test. Detailed instructions will be given to you prior to having the procedure.
