Screening for and diagnosis of GDM
| Glucose measure | Glucose concentration threshold, mmol/L (mg/dL)a | Percentage >threshold (cumulative)b |
| FPG | 5.1 (92) | 8.3% |
| 1-h PG | 10.0 (180) | 14.0% |
| 2-h PG | 8.5 (153) | 16.1%c |
a
One or more of these values from a 75-g OGTT must be equaled or exceeded for the diagnosis of GDM.
b
Cumulative proportion of HAPO cohort equaling or exceeding those thresholds.
c
In addition, 1.7% of participants in the initial cohort were unblinded because of an FPG value >5.8 mmol/L (105 mg/dL) or a 2-h OGTT value >11.1 mmol/L (200 mg/dL), bringing the total to 17.8%.
