Symptoms of Hyperglycemia
Hyperglycemia (high blood glucose) may develop if you do not have enough insulin. There are symptoms
linked to high blood glucose that should not be ignored no matter how mild they are, even if the
Guardian RT does not display a high glucose value or give a high glucose alert. If you have any of the
following symptoms, take a meter blood glucose reading, and check with your doctor before you treat:
Blood Glucose Meter
Be sure to periodically maintain your home blood glucose meter periodically, and check its accuracy
when using it for calibration of your Guardian RT system. Check with your BG meter’s user guide for
information on meter coding, calibration, and testing against solutions and other laboratory instruments.
Ask your doctor about verifying the relative accuracy of your meter, or to find a BG meter that is right for
you.
