Oesophageal pH-Restech Study

Restech test measures and records the pH in your upper oesophagus and larynx to learn if you have Laryngo-Pharyngeal Reflux (LPR). The test can also be done to determine the effectiveness of medications or other treatments for LPR. Restech test is the most suitable test to diagnose reflux from the stomach into the upper oesophagus, that can be either in gas or liquid form.

How is a pH-Restech Study performed?

This test involves placing a thin flexible tube in the back of your nose. The tube passes through the nose, is taped across your cheek, and is connected to a small device worn on your hip that measures reflux over the course of one day (24 hours).

The nasal passage and throat are numbed with a local anaesthetic spray before inserting the tube. You may experience some discomfort in the nose or back of the throat but generally the test is well tolerated.

You will be in the department for approximately 45 minutes. Once the tube has been placed you can leave the department and go about your normal activities.

How to prepare for a pH-Restech Study?

Please do not have anything to eat or drink 6 hours before your procedure. Please take your usual medications on the morning of your appointment with a small sip of water. After the probe has been placed you may eat and drink normally.

If you are taking a proton pump inhibitor (Omeprazole, Losec, Pantoprazole, Somac, Lansoprazole or Solox) then please stop this medication five days before the test.

If you are on any blood thinning medication (e.g. Aspirin, Warfarin, Dabigatran, Rivaroxaban, Ticagrelor, Clopidogrel) and if you are diabetic on insulin please contact the MacMurray Centre on 550 1080.

What happens after a pH-Restech Study?

The following day you will need to return to the MacMurray Centre to have the tube removed. The information from the monitoring device is fed into a computer to analyse your study. You will have a follow up appointment with your specialist to review the results.
