D-Xylose Absorption Test
Why It Is Done
A test for D-xylose is done to:
- Check to see if Reference malabsorption syndrome is causing symptoms, such as chronic diarrhea, weight loss, and weakness. A person with malabsorption syndrome is unable to absorb nutrients, vitamins, and minerals from the intestinal tract into the bloodstream.
- Find the cause of a child's failure to gain weight, especially when the child seems to be eating enough food.
