What is the normal value of glucose tolerance test during pregnancy?

Women need to undergo glucose tolerance test during pregnancy, which can diagnose women with gestational diabetes early, intervene early, and prevent fetal abnormalities. The normal glucose tolerance test is below 5.1 mmol/ml on an empty stomach, below 10.0 mmol/l one hour after oral glucose, and no more than 8.5 mmol/l two hours later.
