Consider Alternate Site Testing When:
• Testing before a meal
• You are in a fasting state
• Two hours have passed since a meal
• Two hours have passed since insulin dosing
• Two hours have passed since physical activity
Use Fingertip When Testing:
• Within two hours after a meal
• Within two hours after insulin dosing
• Within two hours after physical activity
• If you have a history of hypoglycemia, are experiencing low blood sugar, or
suffer from hypoglycemic unawareness (you cannot tell when you have low
blood glucose)
• To confirm your blood glucose level if your AST result is not consistent with
how you feel
• During times of stress or illness
