Pharyngeal pH Testing

Pharyngeal pH testing is used to determine if any of your stomach acid is coming up into your throat or pharynx. If so, this could account for your heartburn, sore throat, clearing, cough or voice changes.

How to Prepare for Testing

Your doctor recommends taking a shower or bath before arriving at your appointment, as you will not be able to once the catheter has been inserted.

Pharyngeal pH Testing Procedure

This test is called ambulatory monitoring, meaning you are asked to go about your daily routine while you are being monitored.

A small catheter is inserted through your nose and down the back of your throat. The tube is taped in place and attached to a receiver and portable recorder. The recorder is worn in a pouch that has a strap that goes around your waist or neck.

The test typically lasts for 24 hours but some may require 48 hours of testing. You will be asked to keep a log of your daily actives and symptoms. This includes:

  • When you eat, lie down and take medications
  • When you experience symptoms such as heartburn, chest pain, coughing or a change in voice

Keeping an accurate log is key, as the information will be compared to the results of the test.

After the test is over, you will need to return to your doctor’s office to have the catheter removed. Don’t forget to bring the log with you!
