The healthcare team will check your blood glucose level before this gestational diabetes testing method. Then you will drink a sugary beverage. The staff will check your blood glucose levels 1 hour, 2 hours, and 3 hours later. If your levels are above normal at least twice during the test, you likely have gestational diabetes.
