pH Bravo testing is a diagnostic procedure used to measure acid levels in the esophagus over a prolonged period. It involves placing a small pH monitoring device (Bravo capsule) in the esophagus to assess acid reflux patterns.
The sensor probe in the capsule measures and records acid levels (pH) at that location over time, and the transmitter sends the information to a recording device you wear on a belt. Doctor Patel downloads this data and uses it to assess the severity of the reflux.
pH Bravo testing helps diagnose gastroesophageal reflux disease (GERD), symptoms such as heartburn or regurgitation (food coming back up into the esophagus) that are not relieved by medication, and evaluating the effectiveness of treatment. It provides valuable information about acid exposure in the esophagus over time.
During pH Bravo testing, Doctor Patel will attach the Bravo capsule to the lining of your esophagus during an upper endoscopy (EGD). The capsule transmits pH data wirelessly to a recorder worn on your belt for 48 to 96 hours.
Before pH Bravo testing, you may need to avoid certain medications and follow fasting instructions. Your doctor will provide specific guidelines to ensure accurate results.
You might need to temporarily stop using medications that suppress stomach acid for a week (7 days) before the test (PPIs or H2 blockers like pantoprazole or pepcid). Or, Doctor Patel may ask you to stay on your regular medications so the test can show how well they are working.
After the monitoring period, you will return the recorder to the surgery center to analyze the data. You can resume your normal activities during the monitoring period. Dr. Patel will discuss the findings and recommend appropriate treatment options.
