Table 5-C represents the alert evaluation within 30 minutes of an SMBG reading for 2- to 5-year old
subjects in the pediatric studies.
Hypoglycemia Alert Rate
The Alert Rate shows how often the alert is right or wrong. The True Alert Rate is the % of time
the device alarmed when the blood glucose level was at or below the alert setting within 15 or 30
minutes before or after the device alarmed. The False Alert Rate is the % of time the device alarmed
when the blood glucose level was above the alert setting within 15 or 30 minutes before or after the
device alarmed.
For example, if you set the Low Glucose Alert to 70 mg/dL and your alarm sounds, how often can you
Software 505 Adult
expect your blood sugar to actually be low? In the Study (Table 5-A), when your
alarm sounds, you can expect your blood sugar to be below 70 mg/dL approximately 92% of the time
and above 70 mg/dL approximately 8% of the time within the 15 minute period before or after your
alarm sounds.
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 blood glucose level was at or below the alert setting and device alarmed within 15 or 30
minutes before or after the blood glucose was at or below the alert 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 or 30 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 will your alarm alert you if your
Software 505 Adult
blood glucose goes below 70 mg/dL? In the 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.
