Rubold, as it goes, the device is great and gives you far more insight into how your blood glucose levels vary with all sorts of circumstances.
I think too many people on the forum set too much store in the absolute value of all blood glucose tests. Yes, this is important, but it is equally, if not more important to know how your body reacts to what you do to it. Outside of a cgm, you won't get a better way than this. If you bear in mind that the variance across different bgm devices can be as much as 12.5% even in the midrange of good blood sugars, the variance in sensor readings is only startling because most people don't test simultaneously across meters.
Even with it, knowing just how fast your insulin takes effect, or that just before you get in the car to drive, your blood sugar test is reading fine, but your blood sugar is dropping at a medium or fast rate, is invaluable. You can't get that from a bgm, and you start to interpret your sensor readings in a far more useful way.
It can't replace bg tests because it will never be as up to the minute as a bg test is, but to discard it due to the noise on the forum is also a mistake. Abbott will have released thousands of these. Those who are happy generally don't make any noise, those who aren't, do.
As a note, I'm extremely happy with mine. I've learned far more about how my bg changes in three days with it than in a lifetime of finger pricking. No, it's not as "accurate" as my bgm, but with a bgm I can't see a likely hypo coming at 5 mmol/l and do something about it, or see a rapid increase going on at 8mmol, both of which are normal readings. Due to this, I think it significantly out performs my bg testing and in three days use I am able to manage my balance better with it than without.[/QUOTE]
My partner is using her second Libre sensor and the results are so random I wonder if anyone has had an answer from Abbott about the accuracy one can expect.
We are simultaneously taking bg readings on an Abbott Xceed meter and the Libre reader.
The differences can be up to 62%. The Libre has given lower readings on 23 out of the last 24 scans. Identical finger prick readings vary enormously on the Libre reader.
Abbott's help line for the UK seemed to be a call centre in Poland that was not very helpful.
