The absorption of xylose following an oral load of 15 g D-xylose has been studied by serial blood levels in 17 untreated adult coeliac patients, 21 treated coeliac patients, and 30 non-coeliac patients. A statistically significant difference in xylose blood levels was found between untreated coeliac and non-coeliac patients at all the times studied, but a complete separation between these two groups occurred only at the 75 minute stage. The reproducibility of absorption was assessed by repeating the test in 16 subjects. The 95% confidence limits of the standard error of estimate are narrowest at 75 and 90 minutes.
通过检测17名未经治疗的成年乳糜泻患者、21名接受治疗的乳糜泻患者和30名非乳糜泻患者口服15克D-木糖后的系列血药浓度,研究了木糖的吸收情况。在所有研究时间点,未经治疗的乳糜泻患者和非乳糜泻患者的木糖血药浓度均存在统计学显著差异,但两组之间的完全分离仅出现在75分钟阶段。通过对16名受试者重复该试验评估吸收的可重复性。估计标准误差的95%置信区间在75分钟和90分钟时最窄。
