A blood glucose test is carried out using a blood glucose meter, sometimes called a blood glucose monitor.
A blood glucose test tells you how much glucose is in your blood at any given time. A blood glucose test is performed simply and easily by pricking the side of your finger tip with a lancet to form a drop of blood. A test strip is inserted into the blood glucose meter and the strip sips in the blood for the meter to test. The blood glucose meter will then count down and display the result.
You will need to measure your blood glucose to help you and your diabetes team decide how best to manage your diabetes and to assess how well your treatment is working. You will have been advised of ways to keep your blood glucose level as near to normal as possible by managing your food intake, exercising and / or by taking medication.
Blood glucose monitoring provides you with a picture of your blood glucose control and indicates when changes occur. By self-testing regularly, recording your results and reviewing them with your diabetes care team, you will learn to adjust your diabetes management to maintain your blood glucose levels within agreed targets.
You should discuss the timing and frequency of blood glucose monitoring with your diabetes care team. You need to carry out enough tests to show your overall blood glucose trends so that you and your diabetes care team can see how well your treatment and management are working and where adjustments might be helpful. The times you need to test should be agreed between you and your care team (e.g. before / after meals), and you should keep a note of the results in your glucose testing record diary. You can also use GLUCOFACTS®Deluxe software to help you understand your results.
At times you may need to increase the number of blood glucose tests you take to get more information and give you a better picture of what is going on, e.g. when you are unwell, following medication changes, at times of increased activity or at times of stress. You should perform a blood glucose test before you drive to make sure that your blood glucose levels have not changed unexpectedly, which would make it unsafe to be in control of a vehicle.
You should agree your target blood glucose levels with your diabetes care team. Discuss realistic targets for various times of the day and activities to ensure that you are safe at all times.
Remember, glucose testing is only of value if you take action to bring your results back into your target range.
In order to use your blood glucose results to guide management successfully, you need to understand how to interpret them. Here are some points to help you do this:
