Patient Information

  • Which breath test is right for me?

    You can book a breath test without a doctor’s referral. If you are referring yourself for a breath test, and are unsure which breath test you need, use the table below as a guide:

    Lactose Breath Test  (to test for lactose intolerance) Recommended for all IBS patients.  Recommended for patients who suspect they get symptoms from eating dairy foods such as milk, yoghurt, soft white cheese, ice cream
    Fructose Breath Test (to test for fructose intolerance) Recommended for all IBS patients.  Recommended for patients who suspect they get symptoms from eating foods such as fruit (eg apples, pears, mangos), vegetables, honey and high fructose corn syrup.
    Sorbitol Breath test Recommended for patients who suspect they get symptoms from eating stone fruits and artificially sweetened mints/chewing gum.
    Sucrose Breath Test This is a rare form of malabsorption and should be considered only if other sugar malabsorption and small bowel bacterial overgrowth have been excluded.   This is intended primarily for children.
    Xylitol Recommended for patients who experience IBS-type symptoms and regularly consume “Diet” and “Sugar Free” foods and beverages including artificially sweetened gum and mints.”
    Methane Breath Test This is included free in your hydrogen breath test

    Choosing can be difficult. If you’re unsure, consider seeking advice from an Accredited Practicing Dietitian

  • Sample Meal Plan for hydrogen and methane breath tests

    For your convenience, we have assembled a Dietitian-approved meal plan for the 24 hours prior to your test.  This diet is designed to optimise the accuracy of the test while keeping you satisfied. Owing to lack of fiber and other nutrients this is not a long-term diet and should not be used on an ongoing basis.  Long term diets should be designed specifically for you, taking your health needs into consideration.

    If you have diabetes, you should consider seeing a dietitian to obtain tailored advice for the preparation period.  We strongly recommend you monitor your blood sugars closely during the 24 hours prior to your test to minimise the chance of significant high or low blood sugars.

    We always recommend seeing an Accredited Practising Dietitian for dietary advice.
