改良斑氏试剂法与醋酸铅法用于粪乳糖检测的比较

A Comparison of Modified Ban′s Reagent Method and Lead Acetate Method on Fecal Lactose Assay

目的:探讨改良斑氏试剂法对粪乳糖检测的准确性。方法:同时采用改良斑氏试剂法和醋酸铅法对60例健康儿、60例非腹泻患儿及200例腹泻患儿同一份大便标本进行粪乳糖检测。结果:200例腹泻患儿采用改良斑氏试剂法检测时,粪便还原糖阳性者138例,占69%,粪便还原糖阴性者62例,占31%;采用醋酸铅法检测时,粪便还原糖阳性者136例,占68%,粪便还原糖阴性者64例,占32%,两者比较,无显著性差异(P>0.05)。结论:两种检测方法对乳糖吸收不良的诊断及治疗同样有一定的价值。

Objective,, To explore the exaction of modified Ban＇s Reagent Method on fecal lactose assay. Methods：Adopting both the modified Ban＇s Reagent and the lead acetate methods, we concurrently assayed their same fecal samples of 60 healthy children, 60 cases of non-diarrheal children and 200 cases of diarrheal children for fecal lactose. Results： Among 200 cases of diarrheal children, 138 （69%）showed positive fecal lactose by modified Ban＇s reagent assay, while 136 （68%） did positive fecal lactose by the lead acetate assay, The differences of two methods were notmarked（P〉0.05）. Conclusion： The two methods for the diagnosis of fecal lactose have a same value,
