Freestyle Libre 2 target range

I have just put on a Libre 2 for the first time in a bid to keep an eye on trends and so on. I'd been doing really well and had got to pre-diabetic and thought I'd got the measure of what I needed to eat but my last bloods showed I'd gone up so I'm keen to sort things out, What better time than Christmas! Anyway, the sensor shows the target range as 3.9 - 10 - is that right? Is 10 ok after a meal and then you wait for it to go down? I've been doing Accu-chek reads a couple of hours after food so would not expect to be so high.

Anyway, I'm fascinated to see how it all goes! Any tips or advice about the target range gratefully received.

@SheilaCanning,

Target range of 3.9 - 10 mmol is the current international standard. To understand how this is intended to be used, you may find the attached paper useful (Highlights are mine).

Also depending on the carb contents of a meal, even non-diabetics can show transient high levels post eating. You may find the Libre 2 very helpful in discovering which foods to avoid or minimise.

That is so helpful! Thank you. I had googled to see if it was a standard range and somehow didn't find the answer. So I suppose even non-diabetics can reach high levels but they will quickly normalise whereas we may struggle to? I've had the Libre 2 on since 21st December so all over Christmas and have been in range 95% of the time which can only get better as there have been some indulgances!

Thanks again.

Mine is set at 4.5 - 10 mmol . I have my alarms set at the 4.5 because I have a history of hypos and the 4.5 gives me an early warning where my sugars are at and I do take note of the directional arrows. I am currently running around 15% out of range, on the above end. I love these devices.

Thank you. I very rarely get below 5 (and feel wobbly when I do). It seems like a really handy device - but expensive!

When I was using the original Libre, I was able to set my own target ranges via my Libre reader. I've always done the same with my meter, and find this more useful for monitoring and control than relying on a more "formal" range. So for me the top of range of 10 is way to high. I'd suggest that if you find you are more or less where you want to be thst you set your range accordingly. (And since - like me - you're a diet controlled T2, I believe you should be safe doing this!)

Thank you. Yes, I might set it down a tad in the future to keep me safe, but for now (especially with Christmas) I'll leave it be.
