§ vs. using BG monitoring, or a CGM system with no predictive alert capability

Proper mobile device, settings and human interaction required.

  1. User interaction required. Diabetes treatment decisions should be made based on a combination of SG readings, trend arrows, glucose target ranges, active alerts, and recent events (such as insulin doses, exercise, meals, and medications)

    InPen™ is intended for single-patient use by people with diabetes for the self-injection of a desired dose of insulin.

    The Guardian 4 sensor is intended for use with the Guardian 4 transmitter to monitor glucose levels in persons with diabetes where self-monitoring of blood glucose (SMBG) is indicated. The sensor is designed to replace fingerstick blood glucose (BG)readings for diabetes treatment decisions. The sensor is intended for insertion into persons ages 7 years and older. The sensor is intended for insertion into the back of the upper arm or the upper buttocks in persons ages 7 through 17 years. The sensor is intended for insertion into the back of the upper arm or the abdomen in persons ages 18 years and older.
