What are the blood sugar ranges for diagnosing pre-diabetes?
Blood sugar levels higher than normal, but lower than diabetic ranges,classify a person as having impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), both of which are used to diagnose pre-diabetes. To check for pre-diabetes, and see how a person reacts to a glucose load, an oral glucose tolerance test (OGTT) may be given to check blood sugar levels 2 hours after being given 75 grams of glucose to drink. The following general guidelines are for normal blood sugar ranges in non-diabetics are from the American Diabetes Association. These guidelines are not intended for “target blood sugar” ranges for people with diabetes. Young children, people newly diagnosed with diabetes, or who are beginning insulin pump therapy will have different target ranges set by their doctor.
