The High Glucose Alert
Estimates of how well the adjustable High Glucose Alert performs are presented in Table 6-A, 6-B and
6-C. Table 6-A represents the hyperglycemia alert evaluation within 15 minutes of the YSI value in the
adult studies. Table 6-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.
Table 6-C represents the Alert evaluation within 30 minutes of an SMBG reading for 2- to 5-year-old
subjects in the pediatric studies.
