[QUOTE="Brunneria, post: 1471606, member: 41816"] Unfortunately, the discrepancy between home blood tests is unavoidable. The manufacturers are required that their tests are =/- 15% of the real figure, almost all the time. Even the same meter will throw out different numbers from the same drop of blood. Basically, they are only broadly speaking accurate. It is very easy to forget this when we use just one meter, and it tests fairly consistently. But as soon as we switch to a different meter, we notice it. In my experience, the Libre almost always tests lower than a finger prick test. And each different sensor tends to be consistent, but will be testing slightly higher or lower than the others. It is a combination of things - where you have it on your arm, tiny variations in the sensors, how your body reacts to the sensor... They all add up to make small differences which then affect the reading. However, having said all of that, as a T2, you don't need total accuracy for insulin dose calculations, and you have already seen huge improvements in your blood glucose due to your diet changes - which has shown up beautifully in your home blood tests. If you use the Libre with the mind set that any individual reading is only roughly accurate [B][I]But the trends, rises, falls, arrows showing speed of rise and fall, are what you need.[/I][/B] It is those that will show you how your body reacts to certain foods and portions, and they will give you an excellent indication of your overall control. Hope that helps! [/QUOTE]
