Caution:
Talk with your healthcare professional before you test palm or forearm.
Do NOT ignore symptoms of high or low blood glucose.
Fingertip samples are able to show the rapid change of glucose faster than forearm samples.
Measurements from alternate site testing should never be used to calibrate a continuous glucose
monitor (CGM) or entered into insulin dose calculators for insulin dosing recommendations.
If the blood glucose test result from the alternate site test does not match how you feel, do a
fingertip test to confirm the result again.
Do NOT change your treatment just because of an alternate site result, do a fingertip test to
confirm the result.
If you do not often notice when your blood glucose is low, do a fingertip test.
What NOT to do:
Fingertip test only:
If sick
If blood glucose is low
After exercising
Two hours or less after eating
When basal insulin is most active
After injecting rapid-acting insulin (two hours or less)
