All you need to know about blood glucose monitoring

Monitoring your blood glucose levels can help you better manage and understand your diabetes.  With regular monitoring, you can see the impact of food, exercise, medication and poor health on your blood glucose levels.  This information can assist you in improving the management of your diabetes.   

The frequency of blood glucose monitoring will vary for each individual, dependant on the type of diabetes and medication being used. It is important to know when to test to provide you with the most useful information.  Some commonly recommended testing times are:

• First thing in the morning (fasting)
• Before a meal
• Two hours after a meal
• Before bed
• Before rigorous exercise
• When you are unwell

The thought of getting a blood sample can make some people feel a bit squeamish.  If used correctly, the lancet devices used to prick your finger are nearly painless and very easy to use.  Here are a few tips to reduce the discomfort of testing:

• Do not re-use the lancet needle as it can become dull and blunt which will make the process more painful
• Prick the side of your finger, not the more sensitive pad
• Don’t use the same finger each time

You may well have heard of newer blood glucose monitoring technology, including continuous glucose monitoring and flash glucose monitoring.  At the moment, both of these technologies have limited use in Australia and are reserved for selected, approved people living with diabetes.

Continuous glucose monitoring (CGM) measures blood glucose levels continuously via a monitoring sensor that is inserted under the skin.  The sensor is disposable and changed according to the manufacturer’s recommendations.  The sensors cost around $5000 per year but some people with type 1 diabetes are eligible to access fully subsidised sensors via the National Diabetes Services Scheme. 

Flash monitoring is a sensor technology that allows you to test your glucose level without pricking your finger.  The system has two parts; a small white disc approximately the size of a twenty-cent coin that holds the sensor and is positioned on the back of the upper arm and a reader.  The reader can be held over the sensor to obtain a glucose reading.  This technology is useful for people who require insulin to manage their condition.
