D-xylose Absorption Test: How To Prepare
Content provided by Healthwise
How To Prepare
For 24 hours before a D-xylose test, do not eat foods high in pentose, a sugar similar to D-xylose; these foods include fruits, jams, jellies, and pastries.
Medicines such as aspirin and indomethacin can interfere with the results of a D-xylose test. For this reason, your health professional may instruct you to temporarily stop these medicines before the test.
Do not eat or drink anything except water for 8 to 12 hours before having this test. Children younger than 9 years old should not eat or drink anything except water for 4 hours before the test.
Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form (What is a PDF document?) .
