It’s time to focus on accuracy

A critical part of taking charge of your diabetes journey is ensuring you use a highly accurate blood glucose monitoring system (BGMS) to measure your blood glucose levels. Self-monitoring of blood glucose is important, as it may help with self-management and medication adjustment, particularly when you take insulin.1 The use of an accurate BGMS makes it possible to minimise errors with decisions related to your food and medication.2


You should review your technique and readings with your healthcare professional regularly, to ensure you are taking accurate readings and that changes to your care can be made quickly and effectively based on your blood glucose levels.1

Accuracy is key!

It is essential to use an accurate BGMS, so that you can feel confident that your blood glucose readings are correct. There is substantial variation in the accuracy of widely used blood glucose monitoring systems. In an independent study, only a third of 18 glucose meters met the accuracy requirements.3

What is hypoglycemia?

According to the The National Institute For  Health and Care Excellence (NICE) hypoglycaemia occurs when your blood glucose level drops below 4.0 mmol/L, and can range in severity depending on how low your blood glucose level falls.1

Preventing hypoglycaemia

When your blood glucose levels are low you may not always have symptoms. This is known as hypoglycaemia unawareness. To detect hypoglycaemia be sure to check your blood glucose levels.4 To lower your risk of hypoglycaemia you should:

  • Eat meals and snacks on time and consume a healthy, balanced diet with the correct carbohydrates
  • Check your blood glucose levels before, during and after physical activity
  • Ensure you adjust your medication or carbohydrate intake based on your blood glucose levels and HCP advice
  • Talk to your healthcare professional if you are regularly experiencing low blood glucose levels

Detecting and treating hypoglycemia

It is important that you recognise the early warning signs and symptoms that occur when your blood glucose begins to drop too low. Please remember that every person is unique and can react differently.

Symptoms of hypoglycaemia include feeling shaky, sweating, feeling hungry, blurred vision, tiredness, dizziness and a headache.4 If you experience any of these symptoms you should:

  • Check your blood glucose levels4
  • If your blood glucose is below target, promptly eat or drink 15 grams of a fast-acting carbohydrate (for example 3-4 glucose tablets or 4 to 6oz of fruit juice).4
  • Wait 15 minutes, and then re-check your glucose level. If your blood glucose reading is under the critical level you have established with your healthcare professional, follow medical advice immediately. 4,5

When looking for a meter for blood glucose monitoring, the CONTOUR®PLUS BLUE system has been shown to deliver highly accurate readings,5 which is important if you have a history of severe hypoglycaemia or regularly experience low blood glucose levels. An accurate meter will help you detect and properly manage hypoglycaemia and assist you to keep your blood glucose levels stable.6
