Comparison continuous measured figures and strips

Good morning, I've been with a freestyle sensor for 4 days and I have doubts about glucose measurement.Which method is more accurate?Is that I have observed differences of up to 45 g/del.Someone can help me.

The most exact, the blood analytics and then a capillary.

It is always said that glucometer is more reliable than the sensor.But if you compare several glucometers to each other, you will see that they are not so.Especially in high values.

It is assumed that glucometers and sensors comply with the ISO 15197: 2013 (Europe) and FDA 2016 (USA) precision regulations that are very similar.

Simplifying +/- 15% for & gt; 100 mg/dl y +/- 15mg/dl for & lt; 100 mg/dl 95% of the time (not even every time).

That putting an example would be that having "really" 200 mg/dl, the devices can mark between 170 and 230 being correct.

In addition, in the sensors, there is the "delay" of about 5 minutes.

Example that happened to me.Sensors 196 uploading vertical.Glucometer at that time 165. And the sensor 170 at 5 minutes.It was what they explain in the course.That the sensor "goes behind"

Another measure of the precision that is usually found is usually Mard (medium relative differentnce, average absolute relative difference).

In glucometers it is usually & lt; 10% and in the sensors to the past of 12% or 14% years ago, to also & lt; 10% in the current sensors.8% or in the most recent sensors.

That means (most of the time) the difference will be less than 10 mg/dl in values ​​close to 100

That translated to compare with each other can give us almost equal or almost 20 values, if one is just the opposite of the other.That being stable.

Actually, I'm just worried that I let me know about hypoglycemia.That matches the measure with what I feel.
