[QUOTE="tim2000s, post: 1925531, member: 30007"] [USER=495267]@TuviaDror[/USER] - I'm not sure how long you think the Libre has been on the market, but it's now a good four years, and the sensor tech is the same as that in the Abbott Navigator. So there's nothing wrong with that. It's also well known that the Libre is not considered to be all that accurate for a fair number of people, however, plenty of others find it to work incredibly well. You are one of those for whom it doesn't. With the best will in the world, there are more Libre users than Dexcom users, so the small percentage complaining will just continue to do that. Without wanting to seem rude, as a corporate, they will understand that there is a proportion for whom the device doesn't really work and will therefore accept that they aren't able to supply you. The thing that is really driving Abbott's desire to improve accuracy is the use of the Libre system with Bigfoot's APS system. The first step of this is to improve accuracy (a MARD of 11.4% doesn't really cut it in AP world) and as someone else mentioned, they are changing the way the calibration is done, which appears to have a significant improvement with Libre 2 (and the US 14-day sensor as well from what I understand). So while you can continue to complain and letter write, both the FDA and Abbott will turn around and say: [LIST=1] [*]Abbott is already improving the accuracy [*]These systems do not work for everyone [*]There are already a ton of warnings about high and low readings and what to do with them [/LIST] It appears that most people are already aware of the limitations of the device, and the key use of it is for understanding the dynamic nature of glucose levels and what you can change to reduce spikes and lows.
