Ordering Information

*We strongly recommend a Lactulose control test to assist in the interpretation of results (see FAQs below for more information). As a default we will assume a minimum of 2 tests per order, unless otherwise indicated by you that you do not wish to include Lactulose.

PLEASE NOTE: Once order is placed and payment made, this cost is non-refundable.



Hydrogen / Methane breath tests diagnoses the following gut disorders known to cause Irritable Bowel Syndrome (IBS) symptoms. Breath tests can be ordered without a doctor's referral. For self-referred patients the below table is a guide only.


For fructose malabsorption, recommended in all IBS patients, especially those with symptoms related to fruits, vegetables, honey and foods containing high fructose corn syrup.


For lactose malabsorption (lactase deficiency), recommended in all IBS patients, especially those with symptoms related to milk/dairy products.


For suspected sorbitol malabsorption. Sorbitol is found in some fruits (e.g. stone fruits) and as a sweetener in sugar-free foods (eg. artificially sweetened gums/mints).


For suspected sucrose malabsorption (sucrase-isomaltase deficiency). Sucrose is found in processed foods (as common table sugar), and in fruits and vegetables.


For suspected mannitol malabsorption, particularly in vegetarians. Mannitol is used as a sugar substitute and occurs naturally in some vegetables e.g. mushrooms, snow peas, cauliflower.

For additional information about these sugars see: Carbohydrate Malabsorption.


Recommended for investigation of small intestinal bacterial overgrowth.


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 donít I just avoid the foods that I think are causing me 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 after I place an order?

A Gastrolab staff member will call you during business hours to collect payment and answer any questions you may have. Your home kit will be posted to your nominated delivery address with all test components and instructions. Follow all pre-test preparations (eg. fasting) and complete tests as soon as possible. Testing simply involves drinking a sugar solution and collecting multiple breath samples for a period of 2-3hrs. After your last test, post all samples together back to Gastrolab.

4. What is a Lactulose control test, and which tests should I order?

We recommend Lactulose as a control test as it provides the following information which may assist interpretation of breath test results: 1) oro-caecal transit time; 2) possible small intestinal bacterial overgrowth; and 3) quantitative assessment of the severity of malabsorption. Fructose and Lactose are the most commonly referred tests, and are recommended in all IBS patients.

5. What do the test results mean?

Your results will be cited by our gastroenterologist, and a report sent to you via email or post. We recommend discussion of your results with a health professional. All patients with positive breath test results should be referred to a trained dietitian/nutritionist for instruction regarding a low FODMAP diet. A list of accredited practising dietitians in your state can be found at: www.daa.asn.au.
