A Bravo pH Study is a wireless acid reflux test that measures acid exposure in the esophagus. It helps determine whether GERD may be causing heartburn, regurgitation, chest discomfort, chronic cough, throat irritation, or symptoms that do not improve as expected.
Medically Reviewed by Dr. Bharat Pothuri, MD, FACG | Updated 06-01-2026A Bravo pH Study uses a small wireless capsule to record acid levels in the esophagus over time. The capsule sends information to a receiver while you continue normal daily activities and track symptoms.
Your gastroenterologist reviews the acid exposure pattern with your symptom diary to see whether acid reflux is likely causing your symptoms.
A doctor may recommend Bravo pH testing when reflux symptoms persist, when GERD is suspected but not confirmed, or when long-term medication decisions need clearer evidence.
The capsule is usually placed during an upper endoscopy. It measures esophageal pH and transmits data to a receiver for the monitoring period.
You may be asked to record meals, sleep times, symptoms, and medication use so results can be interpreted accurately.
Bravo testing does not use a tube through the nose during monitoring.
The test may collect acid exposure information over a longer period than some catheter-based tests.
Results are compared with your symptom record to guide diagnosis and treatment planning.
A Bravo pH Study may be recommended when reflux symptoms are unclear, persistent, or not fully explained by an exam, endoscopy, or medication response. It measures acid exposure over time.
A gastroenterologist is the right specialist for a Bravo pH Study. They evaluate reflux symptoms, decide whether testing is appropriate, and review results with a care plan.
A Bravo pH Study is a reflux test that uses a small wireless capsule placed in the esophagus to measure acid exposure during normal daily activity.
The test records esophageal acid levels and symptom timing. This helps your doctor determine whether GERD is likely causing heartburn, regurgitation, chest discomfort, cough, or throat symptoms.
Bravo testing is wireless and usually records acid exposure for a longer period. A catheter-based test uses a thin tube through the nose for shorter monitoring.
Yes. GastroDoxs may use Bravo pH Study as part of a reflux evaluation when symptoms, medication response, or endoscopy findings need clearer confirmation.
Testing may be considered for ongoing heartburn, regurgitation, chest discomfort, chronic cough, throat irritation, or symptoms that return when acid-reducing medicine is stopped.
It may be medically necessary when reflux diagnosis is uncertain, symptoms persist despite treatment, or objective acid testing is needed before long-term therapy or anti-reflux planning.
Placement is usually brief and may be done during upper endoscopy. Monitoring continues while you follow instructions, record symptoms, and return the receiver as directed.
Bravo testing usually requires review, scheduling, medication instructions, and procedure planning. Same-day placement is not always available and depends on clinical needs and schedule availability.
