title: The excretion of oxypurines in normal subjects.
abstract: Reverse phase high performance liquid chromatography was used for the determination of urinary hypoxanthine and xanthine in normal subjects. The values observed in normal subjects agree with those reported by other authors. Excretion of hypoxanthine and xanthine was not related to sex. Urinary oxypurines were related to age, and, when corrected for body surface area (1.73 m2), they were significantly higher in normal children under 15 years of age than in adults.
