Blood glucose level (BGL)

A blood glucose level (BGL) is the amount of glucose in your blood at a point in time, in Australia it is measured in millimoles per litre (mmol/L). Without diabetes, it generally stays between 4.0 and 7.8 mmol/L through the day.

Also called
BGL, blood sugar level, blood glucose

What it means

As a general guide for people living with diabetes, Australian targets are 4 to 7 mmol/L before meals or when fasting, and 5 to 10 mmol/L two hours after starting a meal. Your own targets depend on your type of diabetes, age, medicines and other health conditions, and are set with your doctor or diabetes team.

BGLs can be checked with a finger prick and blood glucose meter, or tracked with continuous glucose monitoring. A level below 4.0 mmol/L is a hypo and needs treating straight away. Patterns over days and weeks, together with HbA1c and time in range, give the fuller picture.
