- 1-hour glucose level of more than 190 mg/dl indicates gestational diabetes
- 2-hour glucose level of more than 165 mg/dl indicates gestational diabetes
- 3-hour glucose level of more than 145 mg/dl indicates gestational diabetes
- Glycosylated hemoglobin (HbA1C)
- Insulin levels
- Serum acetone
- Electrolyte profile
- Cholesterol levels:
