The California Diabetes and Pregnancy Program recommends that women with values 140 mg/dl to 179 mg/dl should have a 3-hour 100 gram oral glucose tolerance test (OGTT) within one week. If the patient has a screening value > 180 mg/dl, a fasting blood sugar should be checked as soon as possible.
A blood sugar level below 140 mg/dL (7.8 mmol/L) is considered standard. A blood sugar level of 140 mg/dL (7.8 mmol/L) to less than 190 mg/dL (10.6 mmol/L) signals the need for a three-hour glucose tolerance test to diagnose gestational diabetes.
It does not usually diagnose diabetes but is performed to identify those who require additional testing for gestational diabetes. If the test results are below 130 mg/dl (or below 135/140 mg/dl) then no additional testing is required. If the test is above 130 mg (135 or 140 mg) then a 3-hour glucose tolerance test or GTT is ordered.
19 maj 2022 · What the test results mean: If both of your glucose screening tests are abnormal, it means you probably have gestational diabetes. Abnormal results from the three-hour glucose tolerance test are as follows: Fasting: greater than 95 milligrams per deciliter. One hour: greater than 180 milligrams per deciliter.
A glucose screening test is a routine pregnancy test that checks for gestational diabetes (GD). The test checks for higher-than-normal levels of glucose (aka sugar) in your blood, which could mean that you have or are at risk of developing GD.
You will have your glucose tested before consuming a glucose drink and then tested again 1 and 2 hours later. If your glucose is higher than specific cut-off values, it means you have GD. See the table for more specific information.
