What number is considered pre diabetic?

Prediabetes is a condition in which blood sugar levels are higher than normal but not high enough to be considered diabetes. The American Diabetes Association (ADA) defines prediabetes as a fasting blood sugar level of 100 to 125 mg/dL (5.6 to 6.9 mmol/L), or a 2-hour blood sugar level during an oral glucose tolerance test (OGTT) of 140 to 199 mg/dL (7.8 to 11.0 mmol/L).
