Freestyle Libre 2 Sensor

A small, discreet sensor that is worn on the back of the upper arm and continuously measures the glucose concentration in the body's interstitial fluid day and night. The sensor updates the glucose result every minute and stores up to eight hours of glucose readings in 15 minute intervals . It can be worn for up to 14 days and is water resistant so continues to work while you shower, swim or exercise.

The days of routine glucose testing with lancets, test strips and blood are over.
Welcome to flash glucose monitoring!

Flash Glucose Monitoring enables you to test your glucose levels without routine pricking your finger*. The small sensor automatically measures and continuously stores glucose readings day and night.

The FreeStyle Libre 2 Flash Glucose Monitoring System Sensor (“Sensor”), is indicated for measuring interstitial fluid glucose levels in people (aged 4 and older) with diabetes mellitus, including pregnant women. The Sensor is designed to replace blood glucose testing in the self-management of diabetes, including dosing of insulin.

Benefits:

• Small size: (35 mm diameter x 5 mm height) akin to £2 coin – Discreet; the sensor can scan even through clothing
• Requires no finger prick calibration: Eliminates finger pricks needed for calibration
• Optional alarms: high glucose, low glucose and signal loss alarm
• Water-resistant: Can be worn while bathing, showering, swimming, and exercising
• Applied by the patient: Easy-to-use applicator to apply the sensor
• 24 Hours, 14 Days: Automati­cally captures readings day and night. Designed to stay on the back of upper arm for up to 14 days
• With an easy scan: patients can see their glucose variations, including night-time lows

Unlike current blood glucose meters, the FreeStyle Libre Sensor 2 measures the glucose in the body's interstitial fluid with optional alarms. It does not involve painful routine finger pricks. You can scan as many glucose readings as you want whilst the sensor is being worn. The Sensor has a small, flexible tip that is inserted just under the skin.

You need a FreeStyle Libre Reader or have the FreeStyle LibreLink app on your phone to use the Sensor.

It continuously measures the glucose concentration in your interstitial fluid, and stores 8 hours of data. This means that for a complete glycaemic picture, you only need to scan once every 8 hours– enabling you to make more informed decisions about how you manage your diabetes.

Finger prick blood glucose readings and sensor glucose reading won't always match and in fact are likely to be different. That's the interstitial fluid (ISF), a thin layer of fluid that surrounds the cells of the tissues below your skin, not from your blood. There is a 5 to 10 minute delay in ISF glucose response to changes in blood glucose. Glucose readings on ISF have been proven to reliably reflect glucose levels.

Learn how to apply a new sensor for your FreeStyle Libre flash glucose monitoring system as described in the video on the next page for a convenient glucose reading without lancets or test strips.

 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. For a complete glycaemic picture, scan the sensor once every 8 hours.

The reader can capture the data from the sensor when it is within 1cm to 4cm from sensor.

Sensor is water-resistant in up to 1 metre of water. Do not immerse longer than 30 minutes.

For a complete glycaemic picture, scan once every 8 hours.

Patients choose which device they want to receive alarms: FreeStyle Libre 2 reader or FreeStyle LibreLink app. They must start their FreeStyle Libre 2 sensor with that selected device. Once the patient scans their FreeStyle Libre 2 sensor with that device, they can receive alarms only on that device.
