The FreeStyle Libre Flash Glucose Monitoring System is a glucose monitoring device indicated for detecting trends and tracking patterns in persons (aged 18 and older) with insulin dependent diabetes mellitus. Health care professionals and consumers should be aware about the limitations of available scientific evidence for use of this device in any other groups of patients who require diabetes management.

Please check with your Health Care Professional whether this product is suitable for you.

Apply the sensor

The FreeStyle Libre sensor is applied on to the back of the upper arm with a simple, disposable device called an applicator. When the sensor is applied, a thin, flexible and sterile fibre is inserted just under the skin. It is held in place with a small adhesive pad. Most people feel no pain when applying the sensor.1

Scan sensor

To obtain a glucose reading, simply perform a quick, painless 1-second scan of the reader over the sensor. This scan gives you more information than monitoring with blood glucose test strip, without the need for routine finger pricks. The FreeStyle Libre system also offers software to generate concise reports to assist with the analysis of glucose data.

Get reading

Each scan of the reader over the sensor gives a current glucose reading, the last 8-hours of glucose history, and a trend arrow showing if glucose is going up, down, or changing slowly. The reader can even scan through clothing with a thickness of up to 4 mm.2

Please note that FreeStyle Libre sensors have a 5- to 6-month expiration date.


Q: Does the FreeStyle Libre system need to be calibrated?

No, the FreeStyle Libre sensor is calibrated during the manufacturing process so you don't have to. The sensor is activated by scanning and then, after a 1 hour warm up period, it starts to record glucose readings automatically.

Q: 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 a clinical study, the FreeStyle Libre system achieved 11.4% Mean Absolute Relative Difference (MARD) compared to blood glucose testing3
  • 99.7% of glucose results fall within Zone A and Zone B of the Consensus Error Gridwhen compared against blood glucose testing3
    • The measurement errors associated with these zones have no effect on clinical action and little or no effect on clinical outcomes4

Q: Is interstitial fluid an adequate replacement to blood glucose testing?

Interstitial fluid-based glucose readings are a reliable indicator of blood glucose levels5

  • The physiological lag in ISF glucose, with respect to changes in blood glucose, is about 5-10 minutes5
  • The average lag time of the FreeStyle Libre system is approximately 5 minutes, which is unlikely to impact routine day-to-day treatment decisions4, 5

1Most people did not feel any discomfort under the skin while wearing the FreeStyle Libre sensor. In a 2013 US study conducted by Abbott Diabetes Care, 93.4% of patients surveyed (n=30) strongly agree or agree that while wearing the sensor, they did not feel any discomfort under their skin. [29 persons have finished the study; 1 person terminated the study after 3 days due to skin irritations in the area where the sensor touched the skin.] Data on file.
2The reader can capture the data from sensor when it is placed between 1cm to 4cm from sensor, even through clothing.
