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 BG 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 Table 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.
