Diagnosis:

A normal level (for a random blood glucose test) is usually under 125 milligram per deciliter (mg/dL), however, in fasting blood glucose test, a normal level is between 70 to 100 mg/dL

In a fasting blood glucose test, the following results are abnormal and indicate prediabetes or diabetes:

•          A blood glucose level of 100–125 mg/dL shows prediabetes.
•          A blood glucose level of 126 mg/dL and higher indicates diabetes.

In a random blood glucose test, these results are abnormal and indicate prediabetes or diabetes:

•          A blood glucose level of 140–199 mg/dL indicates prediabetes.
•          A blood glucose level of 200 mg/dL and higher shows that the person likely has diabetes.
