Getting to Know Your System
The FreeStyle Libre 2 Flash Glucose Monitoring System (“System”) has
two main parts: a handheld Reader and a disposable Sensor that you
wear on your body. You use the Reader to wirelessly scan the Sensor and
display your glucose readings. The Reader only works with FreeStyle Libre
2 Sensors and cannot be used with other Sensors. The FreeStyle Libre 2
Sensor automatically communicates with the Reader and can give you
glucose alarms if you choose to turn those on. The Reader also has a built-
in meter for blood glucose and ketone testing.
Your System comes in a Reader Kit and a Sensor Kit. When opening your
kits, check that the contents are undamaged and that you have all parts
listed. If any parts are missing or damaged, contact Customer Service.
IMPORTANT: Safety information about the
System is in this User’s Manual. Read all of
the information in the User’s Manual and the
FreeStyle Optium blood glucose and ketone
test strip instructions for use before using your
System.
Interfering Substances
Taking ascorbic acid (vitamin C) supplements while wearing the Sensor
may falsely raise Sensor glucose readings. Taking more than 500 mg of
ascorbic acid per day may aect the Sensor readings which could cause
you to miss a severe low glucose event. Ascorbic acid can be found in
supplements including multivitamins. See your health care professional to
understand how long ascorbic acid is active in your body.
