I´m waiting for my first CGM ever (a Dexcom G4 Platinum).
My question is how to actually benefit from the information I will get from it. I know it´s more of at trend device than anything else, but so is the meters we use.
I am norwegian and the meters allowed for use in my country have an +/- 25% accuracy (I know yours is 20%). In my case this means getting a reading at 6 mmol/l (108 mg/dl) could mean I`m actually anywhere between 4,5 and 7,5 (81-134 mg/dl). This is only a problem if I want to be in tight controll and avoid those over 8-readings (145) and preferably stay in the 5 to 6 range (90-110 mg/dl) before meals and during the night. And I want to be in tight controll.
First question is how you handle the inaccuracy according to your meter.
Second question would be how you handle the added discrepancy of the Dexcom radings. Even though they have improved the sensor it´s still about +/- 20%. And wouldn`t that in fact be on top of the allready where-am-I-actually meter reading?
Oh… and a final question:
Why on earth do we get accurate recommendations from our doctors when accuracy in fact is not obtainable?
