You should follow up with your doctor and get a copy of your labs, but typically borderline diabetes is another term for prediabetes, which is a condition that puts someone at risk for type 2 diabetes. Diabetes is diagnosed with a blood test. Here are the most common ones:

1. A fasting blood glucose or sugar test measures the sugar in your blood when you have not had anything to eat or drink in the last 8 hours.

Condition    Fasting Results (mg/dl)
Normal Below 100
Pre-diabetes 100-125
Diabetes 126 or above

 

2. A non-fasting test can be done when you have had food or drink recently.

Condition    Non-Fasting Results (mg/dl)
Normal Below 140
Pre-diabetes 140-199
Diabetes 200 or above

 

3. A blood test to measure your average blood sugar over the past three months called the hemoglobin A1c test can also be used to diagnose diabetes.

Condition    A1c Results
Normal 5.6% or lower
Pre-diabetes 5.7%  – 6.4%
Diabetes 6.5% or higher

If it has been several years since you last had your blood sugar checked, you should visit your doctor and have it checked again. This measurement should be checked annually at your physical.
