Both sets of study data are presented and are labeled as Original (SW10050) or Software 505
(SW10505).
Low and High Glucose Alerts
The ability of the System to detect high and low glucose levels is assessed by comparing System
results to YSI results at low and high blood glucose levels and determining if the alert may have
sounded. The System and YSI values were compared by pairing the System reading that occurred
immediately after the YSI value was collected. We suggest that you ask your doctor what alert settings
would be best for you.
The Low Glucose Alert
Estimates of how well the adjustable Low Glucose Alert performs are presented in Tables 5-A, 5-B and
5-C. Table 5-A represents the hypoglycemic alert evaluation within 15 minutes of the YSI value in the
adult studies. Table 5-B represents the alert evaluation within 15 minutes of the YSI value for a subset
of the pediatric population—subjects age 6 to 17 years who had YSI measurements every 15 minutes.
