pH Impedance Testing and Esophageal pH Monitoring
pH impedance testing, also called esophageal pH monitoring or 24-hour ambulatory reflux monitoring, is the gold standard for diagnosing gastroesophageal reflux disease (GERD). The test records both acidic and nonacidic reflux episodes inside the esophagus during a 24-hour period. Specifically, it measures how much stomach acid backs up into the esophagus and how long it stays there. It also measures the strength of your stomach acid.
This diagnostic test is especially useful for identifying reflux that may not be acid-related, providing a comprehensive understanding of a patient’s symptoms. By capturing detailed data, pH impedance testing helps doctors pinpoint the underlying causes of discomfort, enabling them to create personalized and effective treatment plans. This minimally invasive procedure plays a critical role in improving symptom management and enhancing quality of life.
How to Prepare for pH Impedance Testing
To prepare for pH impedance testing, patients are advised not to eat or drink anything for 6 hours before the procedure to ensure the stomach is empty, which helps in obtaining accurate measurements. You may be asked not to eat or drink anything after midnight if your procedure is scheduled in the morning.
Your doctor may also recommend temporarily stopping certain medications, such as acid-suppressing drugs, proton pump inhibitors, or antacids, for a specific period leading up to the test. This allows the results to reflect your symptoms more accurately without the influence of medication.
Patients should prepare to wear comfortable clothing and avoid eating or drinking anything in the morning of the procedure. It’s also important to follow any additional instructions provided by your doctor, as preparation can vary based on individual health conditions. Proper preparation ensures reliable results and contributes to a more effective evaluation of reflux symptoms.
What to Expect for Esophageal pH Monitoring
During your procedure, your provider will insert a thin, flexible, disposable probe (the size of a spaghetti noodle) through the nose and throat into the esophagus. The probe will then be securely taped to the nose and cheek with the other end connected to the pH monitoring device.
The monitor is then placed inside a pouch that you will wear at waist level, held by a strap over your shoulder, for 24 hours. You will be instructed on how to use the monitor to record symptoms, meals, and sleep.
The probe will be removed the following day. The data will then be downloaded for analysis and diagnosis by the interpreting physician.
Even though the tube is visible, you are encouraged to go about your regular activities, such as working and eating your normal diet, including any foods that typically provoke your symptoms.
