Esophageal pH Test – Austra Health

The Esophageal pH Test is a diagnostic test used to measure the amount of acid in your esophagus. It is commonly used to determine if acid reflux or gastroesophageal reflux disease (GERD) is the cause of your symptoms. The test can also help evaluate the effectiveness of treatment and detect any changes in acid levels that may be contributing to your health problems.

During the test, a thin, flexible tube with a sensor at the end is inserted through your nose and into your esophagus. The sensor measures the pH level, or acidity, in your esophagus over a 24-hour period. It records the data and gives you a diary to keep track of your symptoms and activities during the test.

The test is typically performed after a period of not eating or drinking anything except water for a specified period of time, usually 6 to 12 hours. This is to ensure accurate results and to reduce the chances of any false negatives or positives. After the test is completed, the data is analyzed and the results are interpreted by a healthcare professional.

The Esophageal pH Test can be used to diagnose various conditions, including acid reflux, GERD, esophagitis, and/or other esophageal abnormalities. It can give valuable information about the presence and severity of acid reflux, as well as identify any triggers or patterns that may be causing your symptoms.

If you have been experiencing symptoms such as heartburn, regurgitation, chest pain, or difficulty swallowing, your doctor may recommend an Esophageal pH Test to help identify the cause of your symptoms and develop an appropriate treatment plan. This test is safe and generally well-tolerated, but there may be some temporary discomfort or irritation in the nose or throat during the placement of the tube.
