In a series of 46 children with untreated coeliac disease and in 102 controls with normal mucosa the 1-hour blood-xylose test was, in view of its simplicity, of much value in the diagnosis of childhood coeliac disease. Only one blood-xylose result was falsely normal in the 46 coeliac patients. It is concluded that a normal blood-xylose value does not exclude coeliac disease and should not prevent peroral biopsy in the presence of strong clinical suspicion. On the other hand, patients who have repeatedly abnormal blood-xylose values merit an intestinal biopsy even in the absence of suggestive clinical symptoms.
在一组46例未经治疗的乳糜泻患儿以及102例黏膜正常的对照儿童中，鉴于其操作简便，1小时木糖血液试验在儿童乳糜泻的诊断中具有很大价值。46例乳糜泻患儿中只有1例木糖血液试验结果呈假阴性。得出的结论是，正常的木糖血液值并不能排除乳糜泻，并且在临床高度怀疑的情况下，不应妨碍进行经口活检。另一方面，即使没有提示性的临床症状，木糖血液值反复异常的患者也值得进行肠道活检。
