What is the Glucose Challenge Screening Test?
No preparation is required prior to the test. During the test, the mother is asked to drink a sweet liquid (glucose) and then will have blood drawn one hour from having the drink, as blood glucose levels normally peak within one hour. No fasting is required prior to this test. The test evaluates how your body processes sugar. A high level in your blood may indicate that your body is not processing sugar effectively (positive test). If the results of this screen are positive, the woman may have the Glucose Tolerance Test performed. It is important to note that not all women who test positive for the Glucose Challenge Screening test are found to have diabetes upon further diagnosis.
