What is a xylose test?
Xylose, also known as D-xylose, is a type of sugar that is normally easily absorbed by the intestines. A xylose test checks the level of xylose in both blood and urine. Levels that are lower than normal can mean there is a problem with your body's ability to absorb nutrients.
Other names: xylose tolerance test, xylose absorption test, D-xylose tolerance test, D-xylose absorption test
