Women in group B were screened by 50 g GCT at 28 gestational weeks and followed by 75 g OGTT for those with abnormal 50 g GCT. The diagnostic effect of 50 g GCT for screening at different weeks of gestation with different ways was evaluated. Results (1)The rate of abnormal result of 50 g GCT was higher in fasting cases than that of cases testing after meal (15.6% vs 12.2%, P
