Esophageal pH Test

The esophageal pH test is used to diagnose and monitor gastroesophageal reflux disease (GERD). It measures the amount of acid present in the esophagus and is most commonly used to evaluate the severity of GERD. The test involves temporarily placing a thin, flexible tube through your nose or in your throat to measure the amount of acid present in your esophagus. It is typically performed in a hospital or doctor’s office and can help to determine the best course of treatment for GERD.

Preparation for the Test

Before the test, your doctor may advise you to avoid eating or drinking for at least four hours prior to your appointment. Certain medications may also need to be stopped before the test. You will also be asked to refrain from gum and mints prior to the test. For the best possible test results, it is important to follow these instructions carefully.

Procedure of the Test

The procedure for the esophageal pH test typically takes less than half an hour. During this time, a thin tube is passed through your nose and gently guided down your esophagus. You may be asked to swallow several times in order for the tube to move further down. Once in place, the tube will remain there for 24-48 hours, during which time it will measure the amount of acid present in your esophagus and transmit the information to a recorder that you will wear. After the test, the tube is gently removed and discarded.

Types of Esophageal pH Test

There are two types of esophageal pH test: the single-probe test and the dual-probe test. The single-probe test involves using a single pH-sensing tube which measures the amount of acid present in the esophagus. This test lasts for 24 hours. The dual-probe test involves placing two pH-sensing tubes in the esophagus and stomach in order to measure acid levels in both areas. This test lasts for 48 hours.

Risks of the Test

Complications from the esophageal pH test are rare, but include slight bleeding, difficulty breathing, and nausea. Additionally, the tube may trigger a gag reflex or cause some discomfort when passing through the nose or throat.

When is it Used?

The esophageal pH test is typically used to diagnose and monitor gastroesophageal reflux disease (GERD). It is the best way to measure and evaluate the amount of acid present in the esophagus. The test is also used to evaluate episodes of chest pain or heartburn and to measure the effectiveness of medication.

Why is it Used?

The esophageal pH test is used to help diagnose and monitor GERD. GERD, a common digestive disorder, is caused by the backflow of stomach acid and other contents into the esophagus. When left untreated, GERD can lead to more serious complications such as irritation, inflammation, and damage to the lining of the esophagus. The esophageal pH test can help to evaluate the severity of GERD and provide important information to help your doctor create a treatment plan.
