There are more Australians living with type 2 diabetes using insulin than people with type 1.

 

Find out more about how Flash Glucose Monitoring technology can help people on insulin to live with greater ease than our grandparents could ever have imagined.

 

Abbott Freestyle Libre is currently the only Flash Glucose Monitoring product available on the Australian market. Often this device is confused with Continuous Glucose Monitoring (CGM).

 

Both CGM and Libre measure interstitial (in between the cells) glucose and provide patterns and trends data to help make informed decisions about your treatment.

 

However, unlike CGM, the Libre does not set off an alarm to alert the user of approaching hypoglycaemia (dangerously low blood glucose levels) or hyperglycaemia (dangerously high BGLs).   

 

The LIbre does not integrate with insulin pump devices like some CGM devices can.  CGM provides a continual display of interstitial glucose whereas Libre requires the scanner to be moved over the sensor to show a result.

 

The Flash Glucose Monitor is made up of a sensor that is inserted just under the skin into the subcutaneous tissue and lasts for 14 days before being disposed.

 

The glucose level is displayed on a scanner that passes over the sensor. The scanner can also be used as a conventional blood glucose monitor and blood ketone monitor.

 

The sensor is waterproof in up to one metre of water for up to 30 minutes and the scanner can capture data from up to four centimetres from the sensor.

 

Conventional finger prick checks should be used in the event of rapidly changing glucose levels and whenever symptoms do not match the scanner result.

 

This is to ensure accuracy when interstitial glucose may not accurately reflect blood glucose.

 

Diabetes Queensland is continuing to lobby the Federal Government to subsidise Freestyle Libre for people using insulin.
