Bravo is the first catheter-free test available to measure and record the pH in your esophagus, used to determine if you have gastroesophageal reflux disease (GERD).Most patients prefer this catheter-free test because it is more comfortable and allows them to continue their daily activities more easily.
Here’s how it works:
A small capsule is attached to the wall of the esophagus during an upper endoscopy. For the next two days, the capsule measures pH levels in the esophagus and transmits readings to a receiver you wear at your waist. You must also maintain a diary to record when you eat, drink, lie down, get up, etc.
To prepare for your test:-
– Stop or delay taking certain medications. This should be discussed prior with your doctor.
– The night before your test, stop eating solid food at midnight.
– Six hours prior to your exam, stop drinking clear liquids
During the testing period:
– Do not alter your daily activities during the monitoring period.
– Eat your regular meals at the usual times.
– Eat foods that tend to cause your symptoms.
– Do not get the receiver wet.
– Do not suck on hard candy or chew gum while being monitored.
– Once the monitoring period is complete, return the receiver and diary to our office where the collected information will be downloaded and analyzed.
