In brief: Lab work

Ask your doctor for lab work.
There are 3 ways to diagnose pre-diabetes. You need two positive tests to confirm the diagnosis: fasting sugar (prediabetic= 100-125 mmol/dl), 2 hr oral glucose tolerance test (2 hr sugar 140-199 mmol/dl) or hemoglobin A1c (pre-diabetic a1c= 5.7-6.4%).

In brief: Fasting blood sugar

The easiest way to know if you have pre-diabetes is by testing your blood glucose.
A fasting blood glucose between 100 and 125 is considered pre diabetes.
