A glucometer is a tool that measures your blood sugar.

Your glucometer shows your blood sugar results in millimoles of sugar per litre of blood (mmol/L).

Buy a glucometer and testing strips at your closest pharmacy. There are many different models of glucometers so talk to your pharmacist about which model is best for you.

How Do I Use a Glucometer?

Your glucometer uses a small sample of your blood. This blood comes from your finger. The glucometer measures how much sugar is in this small drop of blood.

Once the sample of blood is taken, a reading appears on the glucometer screen. The reading will be in mmol/L, such as 5.2 mmol/L. This reading tells your blood sugar level at that exact moment.

What Do I Do With My Glucometer Readings?

Record your blood sugar numbers.

Use the numbers from your glucometer to see how your body responds to:
