Reflux testing

What’s the test for?

This test provides information about gastro-oesophageal reflux and helps to determine if this is causing your symptoms, it is an important part of the investigation and future management of your condition.

You may be sent for this test if you are having reflux symptoms such as heartburn, belching, chest pain, cough or regurgitation.

This test is often performed in combination with oesophageal manomety.

About the procedure

The test involves inserting a small tube (catheter) through your nose, down your oesophagus and into your stomach.  The catheter is attached to a recording device that you will take home with you and wear for around 24 hours.

Your physiologist will explain how the recorder works and will tell you what buttons you need to press and when.  You will need to press buttons when you experience symptoms, when you have anything to eat or drink, and when you are lying down.

You will go home with this in place and continue your normal daily activities including eating and drinking as you normally would to give a good representation of your usual symptoms.

You will need to come back to the clinic on the following day to have your tube removed which takes 5 – 10 minutes.  Alternatively, you can choose to take the tube out yourself which is very simple to do at home and send it and the recorder back to us using a freepost envelope.

If you are paying for this test yourself and not through private medical insurance, the cost will be £1,060.

How to prepare

There is some preparation required before your arrival at the clinic.  This preparation involves stopping certain medication and fasting. Please see our patient information leaflet for full details.

What can be learned

This will measure any acidic or non-acidic reflux you get over this period and how it relates to your symptoms.

Following your test, your data will be analysed, and results written up into a report. The report will be sent to both you and your referring consultant/doctor, who will explain the results to you in a follow-up consultation.

All of the staff were friendly and nice. When I had questions the staff checked on me and made me feel supported. Lovely experience. Everyone had smiles, and they took time to explain and make me feel welcome.
