Show This test is done to evaluate how your body is processing sugar and to determine if you have developed Gestational Diabetes (Diabetes of Pregnancy). The test requires a total of four blood draws. The first is done fasting (after you have had nothing to eat or drink for at least 8-12 hours prior—except water). Then you will be given a glucose liquid to drink that has a specific amount of sugar in it. Blood samples will be taken one, two, and three hours after you have completed this drink. In preparation for this test:
Gestational Diabetes is typically diagnosed when two or more of the results are elevated. Your doctor may also use other criteria to make the diagnosis. Video Transcription: Alberti KG, Zimmet PZ.

On the day of the test typically a patient must arrive in a fasting state.
What is a glucose tolerance test quizlet?Glucose Tolerance Testing (GTT) used to aid in diagnosis of diabetes mellitus or gestational diabetes. Testing. Draw fasting blood sample. Patient given known amount of glucose to drink to challenge system.
Which of the following is used to test for glucose?Blood glucose meters require you to prick your finger with a small device called a lancet. You apply a drop of blood to a test strip and insert it into a small, electronic glucose meter, which measures the glucose is in your blood. Continuous glucose monitors (CGM) use a tiny sensor that you insert under your skin.
