A glucose tolerance test (GTT) is usually done at about 28 weeks of pregnancy to screen for a condition known as gestational diabetes. This simple test involves drinking a bottle of sugar solution over a five-minute period, followed by a blood test one hour later. If the results are abnormal, more testing will be done.

1 AnswerIntermountain Healthcare answeredA glucose (blood sugar) test can help your provider check for diabetes and whether it's in good control. High blood glucose levels can lead to atherosclerosis and artery wall damage. A glucose test may also show if you've had a stressful event (such as a heart attack) that may raise your blood glucose.
1 AnswerBrigham and Women's Hospital answeredA glucose-tolerance test is performed between 24 and 28 weeks of pregnancy to screen for gestational diabetes, which some women develop only during pregnancy. This test is safe and simple and involves the mother drinking a concentrated sugar solution, then having her blood drawn and tested at a timed interval. The results analyze how well her body uses or metabolizes sugar. Diabetes exists when there is a high amount of sugar in the blood because of the body’s failure to handle it normally.
