Hypoglycemic Detection Rate
The Detection Rate is the % of time the device alarmed when the blood glucose level
was at or below the alert setting within 15 minutes before or after the hypoglycemic
event. The Missed Detection Rate is the % of time the device did not alarm when the
blood glucose level was at or below the alert setting within 15 minutes before and after
the hypoglycemic event.
For example, if you set the Low Glucose alert to 70 mg/dL, how often will your alarm
alert you if your blood glucose goes below 70 mg/dL? Based on results for pediatrics in
the G6 Study (Table 5-B), when your blood sugar goes below 70 mg/dL, you can expect
your alarm to sound 81.6% of the time and not to sound approximately 18.4% of time
within the 15 minute period before or after your blood sugar goes below 70 mg/dL.
