In pregnancy, a Three-Hour Glucose Tolerance Test is usually ordered after an abnormal value on an initial one-hour screening test.  \nHow do I prepare for the Glucose Tolerance Test?  \n• For at least 3 days before the test, you should eat an unrestricted diet.

Fasting means you should not eat or drink anything. You may drink sips of water.  \n• If you regularly take prescribed medications discus with your provider which you should take them the morning of the test. Plan to take your prenatal vitamin after the test that day.  \n• Do not exercise on the morning of the test  \nWhat happens during the test?  \n• This test evaluates four blood samples taken over the course of three hours. First, the lab staff will check your fasting blood glucose level. You will then drink a specified amount of Glucola, a flavored sugar drink supplied by the lab. The staff will check your blood glucose levels again atone hour two hours and three hours later.  \nYou must remain at the lab for the duration of your test. Physical activity will affect test results. Bring reading material or other projects to keep you occupied during these three hours.  \nBring a snack for after the test.  \nInterpreting the results of the test  \nMaitri usually receives the results in our office within 24-hours of completion.
