After

After a little research this is what I found in terms of the 3 hour glucose testing results.

Fasting Blood Glucose
From 70 to 99 mg/dL (3.9 to 5.5 mmol/L) - Normal fasting glucose
From 100 to 125 mg/dL (5.6 to 6.9 mmol/L) - Impaired fasting glucose(pre-diabetes)
126 mg/dL (7.0 mmol/L) and above - Diabetes

Gestational Diabetes Diagnostic: OGTT
Target LEVEL
Fasting* 95 mg/dL (5.3 mmol/L)
1 hour after glucose load 180 mg/dL (10.0 mmol/L)
2 hours after glucose load 155 mg/dL (8.6 mmol/L)
3 hours after glucose load 140 mg/dL (7.8 mmol/L)

INDICATION: If two or more values meet or exceed the target level, gestational diabetes is diagnosed.
