You will be asked to take the one-hour glucola test between 24 and 28 weeks of your pregnancy. It is a screening test for gestational diabetes. As a screening test, it is used to determine which patients are at risk for gestational diabetes and need the 3-hour glucose tolerance test. It is not necessary to fast for the one hour test.

If your one-hour test shows that you need to take the 3-hour test (a level of 130 or above), schedule an appointment at Quest lab or Hunter lab for a 3-hour glucola test. Once you have made the appointment, you need to follow a special diet for the 3 days prior to the test. After following the diet, you may have nothing to eat or drink other than water for the 12 hours before your testing.

The special diet is a 150 gram carbohydrate diet. You will need to eat at least this many carbohydrate foods for 3 days prior to taking the glucose tolerance test. You may add extra carbohydrate foods if necessary. The * indicates carbohydrate containing foods. You may make substitutions but you may not omit carbohydrates. If the meals are too large, you may use part of each meal allotment for snacks. You must schedule the test at the laboratory prior to starting the diet and taking the test.
