can non-fasting blood sugar tests done during the day determine if you have diabetes?

More accurate: There are other criteria for diagnosis of diabetes that do not require fasting: random glucose, post meal glucose, hba1c that looks at prior 3 mos of glucose. The fasting glucose is the oldest and most established diagnostic tool. A glucose of >200 at any time of day is generally diagnostic of diabetes.

No: Do get checked from time to time. If it's over 126 mg/dL perhaps on more than one occasion, the diagnosis might be made.
