One-hour serum xylose as an absorption test in the tropics.
The 1-hour serum xylose (surface area corrected) as an indication of xylose absorption after 5 g oral D-xylose has been compared with the 5-hour urine excretion test in a tropical population. The study confirmed that the peak serum xylose concentration occurs at 1 hour and that correction to a constant body surface are improves the discrimination between subjects with normal and impaired xylose...

متن کاملOne-hour blood-xylose in cystic fibrosis.
One-hour blood-xylose concentrations after an oral xylose load were measured in children with cystic fibrosis (CF) and healthy controls. The mean of the 1-hour blood-xylose values was significantly increased in the group with CF. The finding confirms an earlier observation by Rolles et al. (1973). Its significance is not at present understood but it suggests that small intestinal function shoul...
متن کاملThe Xylose Absorption Test in Infancy.
In recent years the d-xylose test has become a standard technique in the investigation of small bowel absorptive function. It has proved to be a simple and reliable procedure of particular value in distinguishing primary small bowel disease from other causes of malabsorption where the defect is essentially one of intraluminal digestion. The test is therefore potentially of value in the paediatr...
متن کاملThe 5 G. D-xylose Absorption Test.
The 5 g. d-xylose absorption test has been studied in 50 normal subjects. The five-hour urinary xylose content was 1.75 +/- 0.43 g. Xylose absorption was more rapid and more complete with the 5 g. than with the 25 g. test. Comparative studies showed the results of the two tests to be significantly related, but the 5 g. test was a less sensitive indicator of malabsorption than the 25 g. test. Th...
