during a meal or exercise, your glucose levels may vary rapidly. Try to time your insertion so that
your calibration times do not coincide with your regular meal or exercise activities.
Note: You should keep your sensor inserted for 5 days. See the exceptions listed above under Start.

Interferents: In vitro and in vivo testing suggest that usual pharmacologic levels of ascorbic acid have
no eect on the function of the system but salicylic acid has minimal eect. In vitro testing suggests
that normal physiologic levels of uric acid, lipids, and bilirubin do not aect system function. e
impact of oral hypoglycemic agents and other potential interfering substances has not been studied.
