TESTING YOUR BLOOD GLUCOSE
CAUTION: Do Not test on your forearm or palm when:
• You think your blood glucose is rapidly falling, such as within two hours of exercise or a rapid-acting insulin injection
or insulin pump bolus. Testing with a ngertip sample may identify hypoglycemia or an insulin reaction sooner than
testing with a forearm or palm sample.
• It has been less than two hours after a meal, a rapid-acting insulin injection or insulin pump bolus, physical exercise, or
you think your glucose level is changing rapidly.
• You are concerned about the possibility of hypoglycemia or an insulin reaction, such as when driving a car. This is
especially important if you suer from hypoglycemia unawareness (lack of symptoms to indicate an insulin reaction).
Getting a blood sample

instructions to get a sucient blood drop for testing.
