Acid Reflux Study – Bravo® Method
Bravo® is a pH-recording capsule used to measure acid levels in the esophagus and to help detect esophageal gastric reflux. The capsule is placed in the esophagus during the endoscopy.
Once the capsule has been attached to the esophagus, it sends readings to the monitor worn on your clothes. This will record all acid readings for the next 48 hours. For two days, you will need to keep a diary of:
- What you eat and drink
- Any symptoms you have
- When you are lying down
The data in the monitor and from your diary will be entered into a computer for analysis.
| Important – Read 1 week in advance with the Endoscopy Health Facts for You
Your test may be cancelled if instructions are not followed
Before the Test
If you are taking medicines to reduce stomach acid, a nurse will tell you whether you should stop them ahead of time (see list below). In special cases, your doctor may instruct you to keep taking them. You may take over-the-counter antacids (Maalox®, Mylanta®, Gaviscon®, Tums®, or Rolaids®) up to 12 hour hours before the test.
- 14 days before the test, stop Nexium® (esomeprazole).
- 7 days before the test, stop Aciphex® (rabeprazole), Prilosec® (omeprazole), Prevacid® (lanosprazole), and Protonix® (pantoprazole).
- 2 days before the test, stop Propulsid® (cisapride), Zantac® (ranitidine), Axid® (nizatidine), Pepcid® (Famotidine), and Tagamet® (cimetidine).
- 12 hours before the test, stop Zelnorm® (tegaserod maleate) and Reglan® (metoclopramide).
Day of the Test
Please review the Endoscopy Health Facts sheet for diet instruction and arrival time. A nurse will review the Bravo monitor and how to keep your diary. The nurse will let you know when and where to return the monitor and diary. Turning them in on time will help your doctor to accurately evaluate your results. These monitors are reused and need to be ready for the next patient.
The test is done at the Digestive Health Center (or one of the locations listed below).
After the Test
Do not have an MRI for 30 days.
