Glucose Tolerance Test


Minister's of Penmai
May 21, 2011
This is an advanced test and is given to pregnant women who have had abnormal levels of blood sugar in their glucose screening test.This test can take about a good chunk of the day—almost half a day. So ensure that you budget time for this. Also, take someone with you or take a good book to keep you entertained and pepped up.Here is how this test is conducted:
  • You will be asked to fast for about 12 hours (check the time with your doctor. Different labs have different times) before attending a special lab where the test will be carried out.
  • When you arrive, a nurse will take a blood sample from you. This is used to measure the level of sugar in your blood when you have been fasting and is called a baseline test.
  • Then you will be asked to drink a sweet glucose drink (more concentrated than what you drank for the glucose screening test)
  • And your blood will be tested again once every 3 hours.
If you do not test positive for any of the 3 sample tests, then you are fine and not diagnosed with gestational diabetes.These 3 blood samples will be tested and compared to your baseline blood sample. If you test positive (have abnormal blood sugar) for only 1 test then, you will be asked to make diet changes and will be tested again. If you test positive for 2 out of the 3 tests, you will be diagnosed with gestational diabetes and the doctor will start treating you for it.
