Performing a Blood Glucose Test with Blood from Your Palm, Forearm, or
Upper Arm (Alternative Site Testing)
w WARNING
• Do not use alternative site testing to calibrate a continuous glucose monitoring
system.
• Do not use alternative site testing to make insulin dosing calculations.
You have the option of obtaining a blood sample from other sites on your body besides the
fingertip. Alternative sites include the palm, forearm, and upper arm.
Blood obtained from the fingertip and palm can be used at any time to perform a blood
glucose test.
If blood from the forearm or upper arm is used, there are certain times when testing is not
appropriate. This is because your blood glucose level changes faster in your fingertip and
palm than in the forearm and upper arm. These dierences may cause you to misinterpret
your actual blood glucose level, leading to improper therapy and potential adverse health
eects. Read the following section before you try testing from the forearm or upper arm.
You may perform a
forearm or upper
arm test
• immediately before a meal.
• while fasting.
You may NOT
perform a forearm
or upper arm test
• up to 2 hours following a meal, when blood glucose values can
rise quickly.
• after injecting bolus insulin, when blood glucose values can
decrease rapidly.
• after exercise.
• if you are sick.
• if you think your blood glucose is low (hypoglycaemia).
• if you sometimes do not notice when your blood glucose is
low.
