D-xylose absorption test is a medical test performed to diagnose conditions that present with malabsorption of the proximal small intestine due to defects in the integrity of the gastrointestinal mucosa. D-xylose is a monosaccharide, or simple sugar, that does not require enzymes for digestion prior to absorption. Its absorption requires an intact mucosa only. In contrast, polysaccharides require enzymes, such as amylase, to break them down so that they can eventually be absorbed as monosaccharides.
No special preparation is needed for D - Xylose Absorption Random Urine. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing D - Xylose Absorption Random Urine.
