Performance of any medical device and health care tool is of the essence. There are three ways to make sure your meter works properly:
Use liquid control solutions:
every time you open a new container of test strips occasionally as you use the container of test strips if you drop the meter whenever you get unusual results To test a liquid control solution, you test a drop of these solutions just like you test a drop of your blood. The value you get should match the value written on the test strip vial label.
Use electronic checks:
Every time you turn on your meter, it does an electronic check. If it detects a problem it will give you an error code. Look in your meter's manual to see what the error codes mean and how to fix the problem. If you are unsure if your meter is working properly, call the toll-free number in your meter's manual, or contact your health care provider.
Compare your meter with a blood glucose test performed in a laboratory:
Take your meter with you to your next appointment with your health care provider. Ask your health care provider to watch your testing technique to make sure you are using the meter correctly. Ask your health care provider to have your blood tested with a laboratory method. If the values you obtain on your glucose meter match the laboratory values, then your meter is working well and you are using good technique.
