Checking your glucose levels by doing a finger prick check tells you what your blood glucose levels are at that moment in time.

Finger prick monitoring involves piercing the skin with a tiny needle so that a drop of blood can be used for testing. You may have also heard this referred to as ‘capillary blood glucose’ monitoring.

For some people this method of glucose monitoring doesn’t cause any problems, however for some it can cause stress and anxiety.

What do I need to do a finger prick check?

To carry out one of these checks you will need:

• A blood glucose meter
• A finger prick device
• Test strips
• A lancet (a very short, fine needle)
• A sharps bin (so that you can dispose of the needles safely)

Recording your readings

It’s important to record your readings in a notebook, diary or app. Some meters have software that allows you to do it directly on the device.

This gives you an opportunity to review your readings over time to identify any patterns that might need you to adjust your treatment.

How do I look after my blood glucose meter?

All meters come with instructions. You should read these and follow them closely. The manufacturer will normally have a helpline you can call for telephone advice. Don’t forget to complete the warranty card and return it to the company.

It is important to quality-control your meter regularly. You can buy a control solution for doing this.

Be in control

Checking your blood glucose levels regularly is one sure way of finding out what's happening to your body so that you control your diabetes, and it doesn’t control you.
