settings. The Hypoglycemia Missed Detection Rate is the % of time
the blood glucose was at or below the alert setting, but the device did
not alarm within 15 minutes before or after the blood glucose was at or
below the alert setting.
For example, if you set the Low Glucose alert to 70 mg/dL, how often

you can expect your alarm to sound 83% of the time and not to sound

your blood sugar goes below 70 mg/dL. Based on the Software 505
Study, if your blood sugar goes below 70 mg/dL, you can expect your
alarm to sound 91% of the time and not to sound approximately 9% of
