glucose meter is a compact, portable device whose main function is to measure glucose levels in the blood. Glucose is a type of sugar found in the blood system and in patients with diabetes, measuring glucose levels is more than essential to be able to control the disease using their blood and ensure that their health is in the best possible condition. .

Glucose meter models

There are many models available which can range from the simplest to some more sophisticated, some with much more basic functions and others more specific, and each of them can be adapted to different types of diabetes and offer different alternatives when taking measurements. routine. The types of glucose meters are:

  • Capillary glucose meter. They are the most used, with a single drop of blood you can present the glucose results in seconds, the results can be seen in moles or milligrams over deciliters.
  • Continuous glucose meter. On this specific model they have a different way of working with respect to the previous one, they calculate the amount of glucose that is between the cells. The technology of this meter is very new and therefore experimental and not as commercialized.
  • Flash type glucose meter. This type of meter compares interstitial fluid levels (that is, the level of glucose between cells, just like the continuous meter), it is highly recommended like the capillary meter because of how simple and practical it is to use.

Aspects to consider when purchasing a glucose meter

When it is necessary to buy a glucose meter, different factors must be taken into account to ensure a good choice in terms of its price and how its functions can be adapted to the needs that are had. The main thing to take into account is:

Due to all this, it can be seen why it is important to make sure to choose a glucose meter that has the necessary precision when conducting this kind of study, essential for those who suffer from diabetes (especially type 2).

How to use a glucose meter?

The way to use glucose meters is simple and does not present many complications. To begin, a test strip must be inserted into the meter; test strips are medical instruments created especially for use in meters.

After the strip has been inserted, a small puncture must be made on the tip of one of the fingers, you must make sure that your finger is completely clean and that you will not need more than a drop of blood for the test, therefore, the puncture should be very slight.

At this point you should gently touch the test strip with your finger and shortly after that the result will be able to be read on the meter screen.

Thus, in a simple way, you can use a glucose meter and obtain the required results in this simple test in a very short time.
