Table 1 Current criteria for GDM prediction

IADPSG

Universal

Fasting plasma glucose test

Fasting glycemia ≥ 92 mg/dL (5.1 mM) predict GDM^d

DGGG

High risk women^a

Random plasma glucose test

Glucose ≥ 200 mg/dL (11.1 mM) proceed with fasting plasma glucose test

Glucose 140–199 mg/dL (7.8–11.0 mM) proceed with fasting plasma glucose test or OGTT

NICE

Women with previous GDM

One-step strategy (2 h OGTT for 75 g glucose overload)

Fasting glycemia ≥ 100.8 mg/dL (5.6 mM)

Glycemia 2 h after overload ≥ 140.4 mg/dL (7.8 mM)

NIH

High risk women^b

Two-steps strategy (1 h GCT for 50 g glucose overload + 3 h 100 g glucose overload)

Step 1: If glycemia ≥ 130 mg/dL (7.2 mM), proceed with

Step 2^e:

Fasting glycemia ≥ 95 mg/dL (5.3 mM)

Glycemia 1 h after overload ≥ 180 mg/dL (10.0 mM)

Glycemia 2 h after overload ≥ 155 mg/dL (8.6 mM)

Glycemia 3 h after overload ≥ 140 mg/dL (7.8 mM)

JOGC

High risk women^c

Two-steps strategy (1 h GCT for 50 g glucose overload + 2 h OGTT for 75 g glucose overload)

Step 1: If glycemia ≥ 200 mg/dL (11.1 mM), GDM is diagnosed

If glycemia ≥ 140–200 mg/dL (7.8–11.1 mM), proceed with

Step 2:

Fasting glycemia ≥ 95 mg/dL (5.3 mM)

Glycemia 1 h after overload ≥ 190 mg/dL (10.6 mM)

Glycemia 2 h after overload ≥ 162 mg/dL (9.0 mM)
