Abstract
Xylose absorption tests were performed on patients unselected except to exclude gastrointestinal or renal disease. The proportion of xylose excreted decreases with increasing age. Intravenous xylose tests suggest that this is due to a deterioration in renal function rather than to a reduction in intestinal absorption.
