Investigation of clinical value of glycosylated hemoglobin test in diagnosing gestational diabetes mellitus.

Objective:To explore the clinical value of glycosylated hemoglobin test in diagnosing gestational diabetes mellitus.Methods:To measure the fasting blood sugar,oral glucose 50 g screen and HbA1c for 60 cases in normal pregnancy women group,60 ones in impaired glucose tolerance group and 56 ones in gestational diabetes mellitus group.Results:The positive rate of HbAlc in normal pregnancy women group,impaired glucose tolerance group and gestational diabetes mellitus group were 3.33%,25% and 80.4% respectively,the difference between normal pregnancy women group and impaired glucose tolerance group was significant(P0.05),the difference between normal pregnancy women group and gestational diabetes mellitus group was also significant(P0.05),the positive rate of the fasting blood sugar in the above three groups were 8.33%,10.0% and 37.5% respectively,the positive rate of oral glucose 50 g screen in the above three groups were 20%,20% and 83.9% respectively.The incidence of complication of gestational diabetes mellitus increased when the level of HbA1c was high.Conclusion:It is a significant value that glycosylated hemoglobin can be used to diagnose and detect gestational diabetes mellitus.
