What is the best way to select a glucose monitor?

You may be looking for an instrument to measure glucose using blood samples or a non-invasive one. There are many things to think about before deciding on a glucose device.


An ideal initial step would be to consult your insurance provider to determine which monitors are covered, either in whole or part. Knowing the price range will help you to narrow down your options. Because you’re likely to go through several test strips daily, it’s an ideal time to determine whether your insurance policy covers tests.


Accuracy is crucial when selecting the best glucose monitor. Since the insulin dose you take, and treatment options are contingent on the results.

This level of consistency must remain the same beyond the laboratory. The meter readings are 15 per cent or fewer, accepted as valid by the FDA. Food and Drug Administration (FDA).

Data display:

Data display is vital since you must clearly see the numbers on the screen. If you suffer from vision issues, having a bigger screen or one equipped with the ability to “say” the results in loud voices can be beneficial.

Some glucose monitors are also equipped with backlighting, making it much easier to look at the display at night or in low-light conditions.

Ease of use:

Because you’ll likely frequently use your device throughout the day, having a simple gadget is helpful. If your device is too complex (e.g. it requires programming or is too lengthy to understand), it’s less likely to utilize it.


The more comfortable you feel with your monitor, the better.

If, for instance, you’re constantly on the move frequently, a compact model could be the best for your requirements. It’s not ideal to feel uncomfortable with a device that’s too small, so it’s a perfect idea to try the size before buying.

Additional features:

Certain features, such as Bluetooth connectivity or storage capacity, make monitors easier and more enjoyable to use. If, for instance, you prefer to record your readings directly on your device rather than writing notes, there are many options available.

It is also possible to find an instrument with dates and times for more information on health-related patterns.

D-Base is an innovative form of CGM that uses heating to monitor blood sugar levels. It was developed by DiaMonTech, a German company.

The breakthrough technology utilizes an infrared laser beam reflected into the skin, which causes glucose within the skin to convert the light into heat. Results are derived from the thermal increase that occurs within the skin. Preclinical studies discovered it to be just as accurate as test strips.

One of the significant drawbacks to this model of D-Base is the dimensions. It’s a stationary shoebox making it challenging to transport. It still needs to be prepared to be sold. The development process is ongoing for this product and other glucose products produced by this company, like the D-Sensor, which is expected to be integrated into watches or fitness bands.

Other meters are being developed.

Apart from the four CGMs, other CGMs are being developed that don’t need a blood sample. One of these CGM is known as the GlucoTrack, created by Integrity Applications which monitors blood glucose through the earlobe. But it still needs to be FDA-certified.

Other technologies could be viewed shortly to manage diabetes without needing finger-pricks. But smartwatches with a standalone design or contact lenses, as well as other devices that are gaining attention, have yet to demonstrate the ability to measure blood glucose levels accurately.

Tips to make monitoring glucose more simple

If you’re using a conventional finger-prick monitor or a CGM to manage your diabetes. Here are some helpful tips to help you check your glucose more easily:

  • Wash your hands thoroughly with soap and water before checking your glucose level for an exact result. Don’t use hand sanitizer before making fingersticks.
  • If you’re putting a sensor on your skin to test for a CGM, cleanse your skin using soap and water, and allow it to dry.
  • Consult your physician if you notice any irritation to your skin or discomfort in your sensor for more than a few hours.
  • Replace any sensor by the recommended manufacturer’s time, for example, every fourteen days with The FreeStyle Libre and every 10 days with the Dexcom G6.
  • If you use finger strips, you might feel less pain if you place the tip of your finger closest to the fingernail.
  • However, if you’re not using a CGM, consider keeping a conventional meter on the side to check your glucose readings. This is if you are experiencing low or high blood sugar symptoms, despite having an average reading.
