如何提高妊娠期糖尿病筛选的准确率——测血糖试验评判标准研究

How to improve the accuracy of screening diabetes in pregnancy-studying the standard of glucose challenge test.

目的观察空腹(至少8h以上未进餐)作测血糖试验(GCT),并以GCT值≥7.2mmol/l为界值,对妊娠糖尿病诊断率的影响。方法以隔夜空腹作测血糖试验(GCT),并以GCT值≥7.2mmol/l为界值,同1天中任意时间(不论末次进餐时间)作GCT,并以GCT≥7.8mmol/l为界值进行对照研究。结果空腹测血糖试验不仅可明显提高筛选敏感度,同时不降低其特异性,从而减少了漏诊。结论空腹作GCT并以7.2mmol/l为界,可提高筛选GDM和G IGT的准确率。

Objective： To observe the clinical rate of diabetes in pregnancy by the glucose challenge test （GCT） on an empty stomach and regard GCT≥7.2mmol/l as standard. Methods ： To study the relation between GCT on an empty stomach （GCT≥7.2mmol/l） and GCT on random time （GCT≥7.8mmol/l）. Results： The glucose challenge test on an empty stomach not only can increasing the screening sensitivity but not decreasing the particular, leading to decrease the missing diagnosis. Conclusion： The glucose challenge test on an empty stomach （GCT≥7.2mmol/l） can improve the screening rate of gestation diabetes mellitus（GDM） and gestation impaired glucose tolerance（GIGT）.
