what should be the glucose levels in tolerance test
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.
