Blood testing with libre scanner

[Bexlee]

Hi All

I wonder if anyone uses the freestyle libre reader to do actual blood tests.

If so how do you calibrate with test solution?

I know how to use test solution!! but I mean when you use control solution and the reader says in this case 8.1 how do I know that’s ok? As I don’t seem to be able to see a range on the strips or box.

With my nexus machine the pot of test strips says control solution range 6.2-8.3 and when used on a strip tested at 7.2.

I’ve had a few unreliable sensors from the same batch which Abbott’s have kindly replaced and they've asked me to do some blood readings using the reader ... I get even odder results !

Results as follows:-

Scan with reader 10.2
Blood with reader 14.3
Blood with nexus mini ultra 9.2
Blood with tee two 9.4

I’ve no idea which to believe. It is a little high as I’ve had a Thai meal for tea!!! 🙂

That is quite a difference between the different glucose readings. If I have any doubts about the Libre sensor reading I do a blood test. I have done these on my pump handset, and also on the reader, but the two blood glucose readings have always been pretty close. They sometimes differ quite a bit from the sensor reading because of the time lag between interstitial reading and blood glucose.

I don’t tend to rely on my sensor for readings to use for insulin doses, I use it to look at trends and spikes. I am aware that others use the readings and apply a bit of a fudge by using the arrows to decide what to enter in their pump.

The range is not on the box but inside the leaflet of test strips.

I use the reader for actual blood tests all the time as it's pretty much identical to the optium neo which I was given anyway. Never really bothered with the test solution as the two machines are normally pretty close.
