Healthcare providers rely on more than one blood glucose test to diagnose diabetes or any other condition. Before people develop type 2 diabetes, they usually have higher than normal pre-diabetic blood glucose levels, but not yet high enough to be diagnosed with diabetes. It can be adjusted to deliver more or less insulin depending on meals, activity level, and blood sugar level.Since food intake affects blood sugar, fasting blood glucose tests show a more precise picture of the baseline blood sugar level.
