Esophageal pH Testing

If you have heartburn, acid reflux (GERD), non-cardiac chest pain, or issues with swallowing, your doctor may refer you for pH testing. We offer two types of esophageal pH testing: pH with impedence testing and BRAVO pH testing. Please discuss with your doctor which may be the right test for you.

24 Hour pH Test with Impedence
pH testing with impedance involves wearing a small, thin tube (catheter) that goes through your nose and into your esophagus. This catheter has sensors that measure acid and non-acid reflux by detecting any liquid and gas that comes up into your esophagus. This test is typically done over a 24-hour period, during which you can go about your usual activities. It helps doctors see if your symptoms are related to acid reflux and how often reflux happens.

BRAVO pH Test (Wireless)
The BRAVO test uses a small capsule, temporarily attached to the esophagus wall during an endoscopy. This capsule wirelessly transmits pH levels to a recording device you wear. The BRAVO test is less invasive than traditional pH testing with impedance, as there's no catheter in your nose and throat. It usually monitors your acid levels for 48 to 96 hours. This test is particularly useful for understanding long-term acid exposure and its correlation with your symptoms.
