Esophageal Ph Test


An esophageal pH test measures the amount of stomach acid that reaches your esophagus. The test lasts 1 to 2 days while you go about your usual daily activities. An esophageal pH test is often used to diagnose gastroesophageal reflux disease (GERD).


Follow up with your healthcare provider as directed:

You may need to return the next day to have your catheter removed. Write down your questions so you remember to ask them during your visits.

Keep a diary during the testing period:

  • Keep your daily routine as normal as possible.
  • Follow your healthcare provider's instructions on what to eat and drink. Write down everything you eat and drink, what time, and how much you consume.
  • Write down the times you were lying, standing, sitting, and sleeping.
  • Write down your symptoms, what time they occur, and your body position at that time.
  • Give the diary to your healthcare provider. He will compare it with the data collected during the test.

Contact your healthcare provider if:

  • You have chest pain.
  • You have questions or concerns about the test.
