Blood sugar testing: Looking into the window of the body

(NC)-For someone who has diabetes, testing blood glucose or sugar is like looking into the window of the body. Regular testing helps a person with diabetes determine how effectively they are managing their diet, exercise and medication. Accurate results from a blood glucose meter are absolutely essential.

Most people would not weigh themselves on a scale that was not reset to zero. It might tell them that they weighed more than they actually did. And much like making sure the scale is reset, people with diabetes need to make sure their blood glucose meter is coded.

Testing blood sugar requires a blood glucose meter and the test strips that are inserted into the meter. They work together to provide the window into the body.

Three things that can affect the accuracy of results are:

  • Humidity - storing test strips in a humid place, like a bathroom
  • Heat - storing test strips in extreme heat, like in a car in the summer. Test strips and meters should always be stored between 15 and 30 degrees
  • Coding - making sure that the meter is coded, just like you would make sure that your bathroom scale is reset to zero before you weighed yourself.


It is hard to believe that only 54 per cent of people with diabetes are aware of the need to code their blood glucose meter, and mis-coded meters can give results that are inaccurate by as much as 43 per cent. This could be significant in the life of someone managing their diabetes.

One option for people with diabetes is the Ascensia line of blood glucose meters, the only product line on the market that offers the "no coding" feature on all blood glucose meters. The meter automatically codes when the patient inserts a test strip. This means a person with diabetes has one less thing to worry about when testing blood sugar and can be confident in the accuracy of their results.
