Overview
Screening
Screening can be performed during the first prenatal visit especially, if mother has risk factors for GDM. If the result is negative or test was not done during prenatal care, 24-28 weeks is the best time for screening mothers.[1][2]
50 gram Glucose Test
Regardless of fasting status of mother, 50 gram glucose is loaded and 1 hour later, plasma glucose level should be measured. Measures greater than 130 mg/dL are considered positive. Considering 130 mg/dl threshold has 88% to 99% sensitivity and 66% to 77% specificity.[3]
- Next step is to confirm the diagnosis by performing a 100 gram 3 hour Glucose Test.

Screening for Gestational Diabetes (GDM)
| "1. Test for undiagnosed type 2 diabetes at the first prenatal visit in those with risk factors, using standard diagnostic criteria. (Level of Evidence: B)" |
| "2. Test for gestational diabetes mellitus at 24–28 weeks of gestation in pregnant women not previously known to have diabetes. (Level of Evidence: A)" |
| "3. Screen women with gestational diabetes mellitus for persistent diabetes at 6–12 weeks postpartum, using the oral glucose tolerance test and clinically appropriate nonpregnancy diagnostic criteria (Level of Evidence: E)" |
| "4. Women with a history of gestational diabetes mellitus should have lifelong screening for the development of diabetes or prediabetes at least every 3 years. (Level of Evidence: B)" |
| "5. Women with a history of gestational diabetes mellitus found to have prediabetes should receive lifestyle interventions or metformin to prevent diabetes. (Level of Evidence: A)" |
