f you're being tested for type 2 diabetes, two hours after drinking the glucose solution:
A normal blood glucose level is lower than 140 mg/dL (7.8 mmol/L).
A blood glucose level between 140 mg/dL and 199 mg/dL (7.8 and 11 mmol/L) is considered impaired glucose tolerance, or prediabetes. If you have prediabetes, you're at risk of eventually developing type 2 diabetes. You're also at risk of developing heart disease, even if you don't develop diabetes.
A blood glucose level of 200 mg/dL (11.1 mmol/L) or higher may indicate diabetes
