Sensor Reader Flash Accurate Monitoring

How does the FreeStyle Libre system work?

To obtain a glucose reading, simply perform a quick 1-second scan of the reader over the sensor.

This easy scan gives you more information than a blood glucose test without the need for routine finger pricks1. The FreeStyle Libre system also offers software to generate concise reports that provide a clear analysis of your glucose data.


1: A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycaemia or impending hypoglycaemia is reported by the system or when symptoms do not match the system readings.

Is FreeStyle Libre accurate?

The FreeStyle Libre system is clinically proven to be accurate, stable and consistent over 14 days compared to blood glucose testing without the need for finger prick calibration, in adult and pediatric patients1,2. Also, FreeStyle Libre is clinically proven to show an outstanding accuracy in the low glucose range1.

2: Finger pricks are required if glucose readings do not match symptoms or expectations

Can the FreeStyle Libre system be used by children?

The FreeStyle Libre Flash Glucose Monitoring System is indicated for measuring interstitial fluid glucose levels in people (age 4 and older) with diabetes mellitus. The indication for children (age 4 - 12) is limited to those who are supervised by a caregiver who is at least 18 years of age.

The caregiver is responsible for managing or assisting the child to manage the FreeStyle Libre Flash Glucose Monitoring System and also for interpreting or assisting the child to interpret FreeStyle Libre readings.

Can I perform a blood ketone test with the FreeStyle Libre system?

You can use the built-in meter to check your blood ketone levels using  FreeStyle Optium Beta-ketone test strips. You should perform a blood ketone test on your fingertip only. Be sure to read the test strip instructions for use prior to using the built-in meter.

Do I need a separate blood glucose meter when using the FreeStyle Libre system?

No. For convenience, there is a built-in FreeStyle Optium blood glucose and ketone meter within the reader that can be used for blood glucose and ketone readings.

Is interstitial fluid an adequate replacement to blood glucose testing?

Interstitial fluid-based glucose readings are a reliable indicator of blood glucose levels1

  • The physiological lag in ISF glucose, with respect to changes in blood glucose, is about 5-10 minutes1.
  • The average lag time of the FreeStyle Libre system is approximately 5 minutes, which is unlikely to impact routine day-to-day treatment decisions1,2.

How should the FreeStyle Libre system be stored?

Both the reader and the sensor should be stored between 4°C and 25°C.

Are FreeStyle Libre sensors and/or readers compatible across different countries and markets?

FreeStyle Libre sensors are programmed for sale in a specific market and are compatible with readers sold, compatible apps and software downloaded in that market.

How do you discard the disposable components, for example sensor pack and applicator?

  • This product should be disposed of in accordance with all applicable local regulations related to the disposal of electronic equipment, batteries, sharps, and materials potentially exposed to body fluids.
  • This means the used applicator and sensor pack should be disposed of in a Biohazard Sharps bin - Clinical waste referral is required from the district nurse or GP, but the majority of people with diabetes will already have the necessary arrangements in place.
