Glukometers must have a certain precision so that health authorities admit it to make medical decisions.

Good joke.But the study that yourself links seems to deny that.Glukometers approved by the authorities have fairly low indices.

For many years magazines and specialized media always put the codefree meter as the most precise and was not sold in pharmacies.But I bought it through UK and after Brexit he got expensive to get.

I will now use and most of the time gives a value close to the sensor.When there is a significant variation, I check it with another glucometer from another brand (normally that of Freestyle) and is usually right the sensor.

I have tried many models and brands and everyone usually has the same percentage of errors.So I keep the cheapest and when I fail, I compare it with another.
