[QUOTE="Celsus, post: 1579742, member: 185674"] And notice [USER=253938]@Diabeticliberty[/USER], for low bgs below 5.6mmol/L it simply states that it should be within the fixed range of [B]± 0.83 mmol/L[/B] of laboratory results. So for very low bgs the uncertainty can become a very high percentage, even near the absolute value you read on the meter. As I described above, you cant really trust any mobile meter when measuring low bg levels, down to the level of digits you showed on your screenshot. For calibration above, you have the calibration chip from Roche you have to use when starting a new batch of strips. Or it wont even allow you to read. That is the only 'calibration' if you will possible of your meter. If you start to consider using calibration liquids on top because you feel the need to double check that it works, then you are out on thin ice already if you don't trust yourself or the equipment you use. E.g. you would then need to measure with calibration liquid before every single test you do. And can you trust the calibration liquid is still good? The questions quickly start to pile up. I think you expect scientific precision, but there is none not even close. You get a good indication about your bg from your meter. That is it. [/QUOTE]
