What is Self-Monitoring of Blood Glucose (SMBG)?

The best way to control your blood glucose levels is by regularly checking small samples of blood at key times throughout the day. Usually, only a pinprick of blood and an accurate blood glucose meter are needed. This process is called self-monitoring of blood glucose, or SMBG.

One of the best ways to be certain that your blood glucose levels are maintained within the Diabetes Safe Zone* is by regularly self-monitoring your glucose level.

Knowing your blood glucose levels at different times of the day can help you and your doctor see how well your meals, activities, medicines and insulin are working and what action to take.

Management Of Diabetes Mellitus

*Ask your doctor about your Diabetes Safe Zone – which refers to the blood glucose levels considered as safe by your doctor.

How To Check For Diabetes


SMBG helps you manage the day-to-day highs and lows associated with diabetes. It will also help you spot the changes in how your body needs insulin over time. Bring your test results to your doctor. They provide critical feedback about how your treatment goals are being met.

When should I self-monitor blood sugar?

Initially, your doctor will determine how often you should self-monitor. Expect to take several samples daily in the beginning. Once your treatment has been fine-tuned, you will settle into the routine of checking your blood glucose levels.
