Laryngopharyngeal reflux (LPR) test

What is a laryngopharyngeal reflux test?

This test provides information on how much reflux you are getting in your throat 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 cough, sour taste, sore throat or burning in the throat and mouth.

How does the laryngopharyngeal reflux test work?

Your nostril and throat will be numbed with an anaesthetic spray while you are sitting upright. A thin tube (2 mm) is passed through your nostril, to the back of your throat. The process of introducing the catheter is done with you fully in control, you can pause and ask questions at any point.

Once in position this will be taped to your nose for the duration of the study. The tube is then connected to a small transmitter which is will be attached to your clothing with a small clip.

The transmitter will then send data wirelessly to a recording box. You will need to wear this for approximately 24 hours, in order to get a good picture of what happens in your throat during the day and night.

Your physiologist will explain how the recorder works and will tell you what buttons you need to press and when. 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.

How much does a laryngopharyngeal reflux test cost?

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

How do you prepare for a laryngopharyngeal reflux test?

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 does the laryngopharyngeal reflux test diagnose?

The recording device used in this test will measure the acidity of your throat over the course of the test, and how this 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.
