Freestyle libre 2 plus

[motherwell1991]

Currently not well and noticed big difference between freestyle libre 2 plus readings and finger tip readings. Freestyle libre plus reading is 3 .0 and finger prick reading is 4.3,anyone else get readings like that

Although startling when your CGM device shows a low reading and it's in red too. Libre's accuracy falls off once you leave that 'normal range'. That's why most diabetics confirm low CGM readings with a finger prick, and use the finger prick as the number to go by. Also there is an allowable accuracy of 15%+/- with all measuring devices so that needs to be taken into account. I would always use the finger prick reading over the CGM when it comes to low readings.

My Libres tend to read lower than a fingerprick by 0.8 - 2 mmol/l at any range below 11, including hypo levels. They've done so since I started using them 8 years ago.

I would always go with the finger prick reading, taking into account low symtoms if you have them.

I have to admit my libres give me a good 10/15 minute heads up on an impending low before I get the early symptoms.

In the early days of using them when they alarmed I thought, “am I heck..?!?”
Then sure enough..

The Libre actually takes the edge of the lows for me so a nominal amount of fast acting carbs averts any real space outs?
It still drops a little further, then the lag of recovery on the graph. But then I used to see that testing every 5 minutes with a meter too…(the meter tended to show a quicker response time to treatment.) my brain function was still ahead of both..

So not only outside normal range, it's always worth the occasional fingerprick to get to know your Libre.

I wish mine did too!
I usually catch my lows before Libre even knows, even without symptoms.

That’s how I got to know the L1 using a Bluetooth bridge as a “CGM.” & the 2 successors.. not much difference for me..

Without fail (to date.) unless it’s a compression low waking me?
But then I got 15mins to see it bounce back.
I’m slow to wake though normally feel the low if I am when I do…
Real hypos on a graph for me look like they have been happening for 45 minutes.
In reality. A third of the time by the time I’ve treated it?
