Hypoglycemia Detection Rate
The Detection Rate shows how often the device recognizes and alerts you to
an episode of hypoglycemia or how often it misses such an event. The
Hypoglycemia Detection Rate is the % of time the BG level was at or below
the Alert setting and device alarmed within 15 or 30 minutes before or after
the BG was at or below the Alert settings. The Hypoglycemia Missed
Detection Rate is the % of time the BG was at or below the Alert setting, but
the device did not Alarm within 15 or 30 minutes before or after the BG was at
or below the Alert setting.
For example, if you set the Low Glucose Alert to 70 mg/dL, how often will your
Alarm alert you if your BG goes below 70 mg/dL? In the
Software 505 Adult
Study (Table 5-A), when 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 time within the 15 minute period before or after your blood sugar goes
below 70 mg/dL.
