At the first antenatal visit, IADPSG recommends screening pregnant women for GDM using standard criteria to diagnose diabetes in non pregnant state to identify women with overt diabetes “pre-existing diabetes”. A diagnosis of overt diabetes can be established in women who meet any of the following criteria: fasting plasma glucose level (FPG) ≥7.0 mmol/l (126 mg/dl), a casual plasma glucose of 11.1 mmol/l (≥200 mg/dl), or HbA1c ≥6.5. In the absence of unequivocal hyperglycemia, the diagnosis must be confirmed on a subsequent day. Confirmation of the diagnosis precludes the need for OGTT. If FPG is >5.0 mmol/l (90 mg/dl) but
