Hydrogen/Methane Breathtesting

Diarrhoea | Gastrointestinal Symptoms | Bloating | Cramps | Constipation 

High Street Medical Clinic provides breath testing for food intolerances, specfically sugar malabsorption such as lactose intolerance and fructose malabsorption, which typically generate symptoms commonly referred to as Irritable Bowel Syndrome (IBS).

Hydrogen and methane breath testing is available for a range of sugar malabsorption and gut disorders for referred and self-referred patients (a doctor's referral is not required).

1. Why should I take a hydrogen/methane breath test? 
Patients with Irritable Bowel Syndrome (IBS) experience chronic or recurrent gut symptoms such as abdominal bloating, discomfort and diarrhoea/constipation. These symptoms may be caused by dietary triggers. Malabsorption of certain dietary sugars (called FODMAPs) is a leading cause of IBS symptoms. Medical and allied health professionals request these tests for their patients during the diagnostic work up of IBS symptoms.

2. Why don’t I just avoid the foods that I think are causing my gut problems? 

A reduction/elimination diet has many limitations; mainly they are protracted, unscientific and have poor diagnostic accuracy. Further, FODMAP malabsorption is different to (but often confused with) coeliac disease, food allergy and food chemical sensitivity. Breath tests are highly specific and sensitive diagnostic tools. A proper diagnosis can confirm whether FODMAP malabsorption is the cause of IBS symptoms, thereby guiding subsequent dietary management and avoiding unnecessary food restrictions.

3. What is the procedure for completing home kits? 

You will need to attend the clinic to pick up and pay for your kit. Testing simply involves drinking a sugar solution and collecting multiple breath samples using a specialised mouthpiece and collection vials for a period of up to 3hrs. Testing can be performed at home and even at work, as long as there is no substantial physical exertion involved at work (eg. office and sedentary work).

After your last test, post all samples together back to the nominated adress without delay. Reply paid labels, Australia Post tracking labels and tamper evident seals are included for posting samples back.

4. How quickly do I need to complete the tests, and in what order?

To ensure best results, complete all tests as soon as possible; we recommend one test is performed every 2-3 days. You do not have to complete tests in any specific order, however we suggest you perform the compulsory Lactulose test first. After your final test, post all samples back  immediately for analysis.
