percent (85%) of the sensors lasted until at least the start of Day 7
(145-168 hours).
Number of Readings Provided
The System is capable of providing a reading up to every 5 minutes,
or up to 288 readings per day. For a variety of reasons, the System
may not display a glucose reading and readings are “skipped.” Table 9
estimates the number of readings you can expect to receive from the
System over the entire 7-day period after calibration. Adjusted within
each system wear-day, the System provided an average of 95% of all
expected glucose readings as seen in Table 10.
