Clinical significance of oral glucose tolerance test on gestational diabetes mellitus

目的:探讨妊娠糖尿病(GDM)孕妇妊娠期口服糖耐量试验(OGTT)的价值。方法:对2008年5月～2010年5月产前检查孕24～34周经口服50g葡萄糖筛查1小时血糖>7.8mmol/L的孕妇进行OGTT试验。结果:孕24～28周与孕30～34周两组比较,50g糖筛查率差异无统计学意义(P>0.05),OGTT异常率、GDM率差异有统计学意义(P<0.05)。结论:口服糖耐量试验可用于确诊妊娠糖尿病,了解血糖波动范围,分析妊娠糖尿病稳定程度。
