Xylose Tolerance Test

What can the Xylose test be used for?

The Xylose test can be used to monitor coeliac disease management due to its good correlation with histological damage and it also assists in the diagnosis of food intolerances, malabsorptive conditions and Irritable bowel syndrome.

Results of the Xylose test will enable your treating health practitioners to evaluate whether you are malabsorbing food, may help in diagnosing and will help guide your treatment plan.

Irritable Bowel Syndrome


Symptoms of Xylose malabsorption may include:

  • chronic diarrhoea
  • weight loss
  • malnutrition


Testing for Xylose Intolerance

This test involves xylose being given as a solution in water to drink, with Hydrogen/Methane breath testing and symptom monitoring being performed at regular intervals for 2-3 hours to determine intolerance. You will need to commence this test in a fasted state.
