Abstract

OBJECTIVE
To evaluate the relationship between results of 50-g one-hour glucose screening test (50 GTT) and gestational diabetes and to find cut-off result value of 50 g GTT which can diagnosis the gestational diabetes without other confirmative tests. METHODS: Retrospective study were performed from 1353 pregnant women between 24-28 weeks of gestation, whose results of 50 gGTT were the same or above 140 mg/dl. The diagnosis of gestational diabetes was determined by 100-g 3-hour oral glucose tolerance test (100 gGTT) result. RESULTS: From 1998 to 2002, One hundred twenty-six pregnant women were diagnosed as gestational diabetes among 1353 pregnant women performed 100 gGTT. We couldn't decide any diagnostic cutoff value to gestational diabetes. There was a correlation between the results of 50 gGTT and the incidence of gestational diabetes (p<0.0001). Twenty-one (63.64%) patients among 33 patients whose 50-g screening test result
