III. Precautions
- See Diabetes Mellitus for evaluation and management of initial evaluation and management of Hyperglycemia
- Serum Glucose >250 mg/dl may be associated with Serum Ketone production
IV. Interpretation: Normal
-
Fasting Blood Sugar: <100 mg/dl
- Reflects Insulin Resistance, hepatic production and overnight Glucose secretion
- Postprandial 2 hours: <140 mg/dl
- Reflects pancreatic islet cell response to a meal (endogenous Insulin secretion)
- Blood Glucose may in some cases rise as high as 160 mg/dl after a large meal in a non-diabetic patient
- Stress response
- Typically Serum Glucose <200 mg/dl
