In uncompensated insulin deficiency, fasting glucose is abnormal; in compensated insulin deficiency, a variety of carbohydrate tolerance test […]

The blood specimen itself is important; according to several reports (and my own experience), during each hour of standing at room temperature, whole blood glucose values decrease about 10 mg/100 ml unless a preservative is added.
