Gastroesophageal Reflux Test

Gastroesophageal Reflux Disease (GORD) is caused by a weakening in the esophageal sphincter, which allows stomach acid to flow back up into your esophagus. This constant flow of stomach acid irritates the lining of the esophagus, causing inflammation and discomfort.

Our Gastroesophageal Reflux Test accurately detects the presence and determines the extent and severity of GORD.

Your GP or specialist may refer you for this test if you are suffering from:

Heartburn, cough, chest pain, throat clearing, difficulty swallowing, recurrent chest, throat and/or ear infections, sinusitis, pneumonia, bronchitis, new or worsening asthma or disrupted sleep.

In many cases, patients may not present with classic symptoms of Gastroesophageal Reflux Disease but are suffering from typical upper respiratory tract symptoms such as chronic cough, dysphonia and globus.

This is due to reflux fluid contaminating the maxillary sinuses, throat, middle ears and laryngopharynx. It may also contaminate the airways and lungs causing asthma-like symptoms, chronic cough and recurrent bronchitis or pneumonia.

The appealing point of difference of our Gastroesophageal Reflux Test in comparison to other reflux investigations is the method and accuracy in which patient results are extracted and interpreted.

Our Nuclear Medicine Physician, Dr Hans Van der Wall, has developed a patented software to effectively indicate the severity of the GORD and the likely outcome of laparoscopic anti-reflux surgery with the intention to almost negate the risk of an unsuccessful surgery entirely.

You are required to fast for 4 hours prior to your examination. Please do not have anything to eat, drink, smoke or chew during the fasting period. All medications (including prescribed reflux medication) must be taken on the day of your examination prior to the 4 hour fasting period. Gaviscon must NOT be taken on the day of your appointment.

Part One

The Nuclear Medicine Technologist will give you approximately 150mL of water to drink. The water is labelled with a slightly radioactive tracer. 35 minutes of imaging will commence after consuming the water.

Part Two

Following part one, there will be a 90 minute break. During this time you must continue to fast, however you may leave the department. The Nuclear Medicine Technologist will advise you of when you need to return to the department.

Part Three

 Upon your return, a further 25 minutes of imaging will be performed.

Our Nuclear Medicine Physician will review the images and issue a report. Once completed, the report will be sent electronically to your referring health professional.
