Blood glucose monitoring

Monitoring your blood glucose levels is an important part of looking after your diabetes.

Ways to monitor your glucose levels

Glucose monitoring helps you keep your glucose levels in your target range, so you can stay healthy and lower your risk of diabetes-related complications. There are three main ways to monitor your blood glucose levels.

Haemoglobin A1c blood test

Haemoglobin A1c (HbA1c) checks

An HbA1c check shows your average blood glucose levels over the past 10 to 12 weeks.

Continuous glucose monitoring (CGM)

CGM devices are small, wearable monitors that track your glucose levels through the day and night.

Blood glucose highs and lows

It is normal for your blood glucose levels to go up and down over the day, even when you are managing your diabetes well. The key is monitoring them, understanding the causes, and knowing when to act.
