Message: <blockquote data-quote="Deleted Account" data-source="post: 1570828">I don't get your comment about using your Libre for 50 - 100 times a day. Do you mean you have been scanning it that many times and have calculated your predicted Hb1AC based on the value at the time of your scan?The Libre sensor in your arm is regularly testing your BG based on your interstitial fluids (slightly different to the glucose in your blood but close). Unfortunately, I cannot find anywhere online which states how often it does this test. It stores the last 8 hours of results on the sensor. When you scan the sensor, you are downloading the last 8 hours of data. If you scan less often than 8 hours, you will miss some data because the sensor only have enough memory for 8 hours. Back to my confusion around your 50 - 100 uses per day: you have more than 100 data points downloaded to your reader. If the sensor tests every 5 minutes, you have nearly 300 data points per day. Apologies if I have misunderstood your statement. I find it frustrating that many people do not seem to understand the power of the Libre: it is in its history and trends not single point-in-time readings. Using a Libre as a replacement for finger pricking is like using a Smart Phone just to make phone calls. If the NHS is to get any value from prescribing Libre, I believe they should invest in some education of the users. <Sorry, I didn't mean to hi-jack this thread for my soapbox></blockquote>
