Criteria for the diagnosis of overt diabetes in pregnant women at their initial prenatal visit

1. A1C>6.5%. The test should be performed in a laboratory using a method that is NGSP certified and standardized to the DCT assay^*

2. FPG>126mg/dl (7.0mmol/L). Fasting is defined as no caloric intake for at least 8 h^*

3. A 2h plasma glucose >200mg/dl (11.1 mmol/1) during an OGTT. The test should be performed as described by the World Health Organization, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water.^*

4. In a patient with classic symptoms of hyperglycemia or hyperglycemic crisis, a random plasma glucose >200mg/dl (11.1 mmol/1)

DCT, direct contact test; FPG, fasting plasma glucose; OGTT, oral glucose tolerance test.

In the absence of unequivocal hyperglycemia, criteria 1–3 should be confirmed by repeat testing.
