Meter Comparisons: do you use Freestyle Libre and/or SD Codefree

Because one glucose meter is never enough.....


If you have either of the above, plus a different sort of meter, do you see one reading consistently higher or lower than the other?

My Libre is telling me my numbers are excellent (apart from the leek and potato soup at lunchtime) - but I suspect it may be reading a little low. Or is the CodeFree reading a little high? Or a bit of both?

Sometimes both say the same - or within a few fractions of a mmol. When there is a difference, it's always the Libre that's lower. The largest discrepancy I've seen is just over 1 mmol/l - which if you reckon in the accuracy they are allowed, is not out of order. But it probably means my true reading is somewhere between the two.
 
Hi Barbarag don't know anything about the Libra but I use two different meters and they very seldom give the same reading as long as there not a long way out should be fine all new meters have got comply to a standard of accuracy hope this helps?
 
Both my 10yr old Optium Plus and my Neo read the same on the tests I have done, mainly to verify I can be sure the Neo will work ok for me if and when my Optium pegs out...........:watching:
 
I use the Libra and so far I find that each different sensor seems to have characteristics of its own. The current one is reading low, the previous one read high.

Once or twice in the past I have tested a few meters against a known control solution. Until recently the SD always read high but on the very last set of tests it read low. I may re-visit that test since if it has changed in any way then the SD will be a lot more useful than before.

The bottom line is they may be high they may be low but only the Freedom Freestyle Lite has got it right every time.
 
Yup, the Libre is always lower than my SD Codefree.

The difference seems to be vaguely consistent for each sensor, then the new sensor will be different, but consistent. If that makes sense?

When I first got the SD Codefree it was a replacement for another (more expensive) brand. And I can remember being pretty shocked at how much higher the Codefree was than the old brand.
But I decided to take it as motivation to work harder at keeping the numbers down. lol.

Now, with the Libre, I find the numbers much less important (since they vary with every sensor) than the trends and arrows and daily variations. They tell me so much more than the Codefree's snapshot glimpses of what is going on.
- I have virtually stopped using the Codefree altogether, and now use a Libre sensor every few weeks and don't test much at all, in between.
 
I have a Libre, a Codefree and an Accu Chek Mobile.

I find each separate Libre sensor to be individual and never the same as the previous one. Like @Brunneria said, each sensor is consistent so, ignoring the numbers, I can believe the daily variability on the graphs. The actual numbers don't bother me. The next sensor may read higher or lower than the previous one, but will still be consistent so again I can believe the graphs.
The estimated HbA1cs have been laughable.

I did have one sensor that was erratic and nowhere near consistent. It was low. It was high. It threw out silly numbers, high and low. Abbott replaced it.

In many comparison tests, on average, the Codefree reads higher than the Libre and the Accu Chek. The Accu Chek is somewhere in between normally, but closer to the Libre..

My last sensor average (on several comparison tests) was 5.3
Codefree was 6.1
Accu Chek was 5.4
