[QUOTE="Bluetit1802, post: 1518443, member: 94045"] Are you aware that the Libre sensors read interstitial fluid, not capillary blood?. The interstitial fluid runs about 10 to 15 minutes behind our blood meters. This means you need to finger prick first, wait 10 to 15 minutes, then scan the sensor. Blood glucose meters have an error tolerance of plus or minus 15% (95% of the time. The other 5% can be anything) It is unusual to get identical readings with consecutive finger pricks. Blood runs round our bodies very quickly, and each drop you get contains many, many blood cells. Each blood cell will have a different amount of glucose attached to it. I would put one meter away and use the other for some comparison tests against the Freestyle Libre. All my Libres have read a lot lower than my finger pricks, BUT have been consistent. I have been able to average the differences between the Libre and the finger pricker, and mentally add that difference to the Libre readings. [/QUOTE]
