Our minute-to-minute glucose monitoring system, FreeStyle Libre 2, uses a small, discreet and easy to use1 sensor. It provides your patients with real-time glucose readings on their smartphones◊ day and night.
Measures glucose levels in blood
Measures glucose levels in interstitial fluid
Comfortable to wear2, no finger pricks† so patients can manage their diabetes painlessly.2
Automatically measures, captures, and stores glucose data day and night for up to 14 days3
Sensor delivers readings directly to your patients smartphone◊,ǁ
Provides the whole picture about both the current glucose level and changes over timeφ
Continuous glucose monitoring help to see the impact of activities and food
Proven to reduce time in hypoglycaemia2,5 and improve overall glucose control4,5
The FreeStyle Libre 2 sensor is a small, unobtrusive, and easily applied2 to the back of the upper arm. The sensor comes with an applicator and uses a small, flexible tip that is inserted just under the skin.
The FreeStyle Libre 2 sensor continuously measures glucose readings through the whole wear period.
Patients who start their sensor using the FreeStyle LibreLink◊ can see their glucose levels in real-timeII and receive optional alarms if they are too high or too low.¤
Alarms are available for FreeStyle Libre 2 reader users also^
Glucose in the blood takes time to make its way into the interstitial fluid so there may be a lag time between the readings.
When glucose levels are stable, the two readings may be very similar. However, if glucose is rising or falling, then they might be different.
When blood glucose levels are stable,
the glucose measurement displayed by the FreeStyle Libre 2 sensor in the interstitial fluid, is similar to blood glucose.
When blood glucose levels increase,
the glucose measurement displayed by the FreeStyle Libre 2 sensor in the interstitial fluid may be below the blood glucose reading.
When blood glucose levels decrease,
the glucose measurement displayed by the FreeStyle Libre 2 sensor in the interstitial fluid may be higher than the blood glucose reading.
The FreeStyle Libre 2 system has an overall 9.2% MARD with 99.9% of readings in Zones A and B of the Consensus Error Grid without the need for finger prick calibration.6
93.2% within ±20/20%6
Percentages of total readings within ±1.1mmol/L of YSI reference values <4.4mmol/L or ±20% of YSI reference values ≥4.4mmol/L.
The FreeStyle Libre minute-to-minute glucose monitoring system offers uncompromising quality and reliability for you and your patients.
with quality ensured through rigorous testing and precise factory-calibration
so your patients can rely on every reading. Every sensor conducts over 20,000 self-checks during its wear period.
with documented highest levels of safety and accuracy.
to ensure adherence to local privacy and cybersecurity standards to provide safeguarding of all personal health data.
with a specialist team available to help with simple or complex questions, as well as quick and free of charge sensor replacements for patients.
Calibration is needed for commercially available CGM systems because the sensitivity of each sensor can vary within each batch that is made. The FreeStyle Libre 2 sensor is calibrated at the factory – so your patients won’t need to calibrate it using a finger prick, ever. This means you and your patients can be confident in the accuracy of the system, and that the accuracy you're receiving is what is reported, without being affected by discrepancies caused by finger prick calibration.
