Do not change your treatment because of just one result.
NEVER ignore symptoms of high or low blood sugar.
If your blood sugar does not match how you feel, do a fingertip test to confirm your result.
If the fingertip result still does not match how you feel, call your doctor.
Tests from sites other than your fingertip may be done:
• Immediately before a meal
• Fasting
Fingertip test only:
• Two hours or less after eating
• After exercising
• If you are sick
• If you think your blood sugar is low
• If you often don't notice when your blood sugar is low
• During peak action time of short-acting insulin or rapid-acting insulin analogues
• Up to two hours after injecting a short-acting insulin or a rapid-acting insulin analogue
