Also known as: 24-hour pH impedance, 24-hour esophageal impedance pH test.
The pH of something refers to its acidity on a scale. An esophageal pH-impedance study is a test performed in the esophagus that helps to diagnose acid and non-acid reflux.
Guided by X-ray, medical professionals will pass a catheter through the nose and into the esophagus. The catheter has an acid and non-acid-sensitive tips that measure pH levels in the esophagus over a 24-hour period. This information is then used to make a diagnosis and can be used to guide treatment.
The patient may need to avoid foods, drinks and certain medications for a period of time before the test.
