Have you been running higher levels lately? If so, it could've been a false hypo at 5.2.Taking all this into consideration, has anyone else experienced the libre reading low 3.4, me feeling low, but finger pricking showing 5.2?
Not particularly, my highest numbers are usually only 12ish, but that's only if I'm going to exercise or until I notice and then I would correct.Have you been running higher levels lately? If so, it could've been a false hypo at 5.2.
A false hypo is when you've been running higher numbers for a while and you start to feel hypo at above hypo levels. Like when you've been above 8 all the time for some time you can well feel hypo at 5.5.And I felt hypo also.
I'm a new user of Freestyle Libre, only on my second sensor.
I know that it has a lag time and that both the libre and finger pricking is never going to be 100% correct. And that you should always trust finger pricking to be more accurate than the libre.
Taking all this into consideration, has anyone else experienced the libre reading low 3.4, me feeling low, but finger pricking showing 5.2?
This has happened twice recently and really puzzles me. I spoke to DSNs about it and I think she thought I was making it up, the only thing she said to explain it would be if maybe my hands weren't clean whilst blood testing. But it has happened again now, so I sincerely doubt this will be the case twice, especially how much I'm washing my hands lately!
Any suggestions greatly appreciated.
Apparently 31 times a day on average over the last 3 months, plus a couple of fingerpricks every day. I've been using the Libre for over 3 years now.How often are you all scanning? At the moment (2nd day) I’m experimenting with once an hour but plan to mirror my finger pricking.
That's up to you and your consultant. Some hardly ever do a fingerprick test, others double check every day.I’m on my first sensor, how often should I finger prick test or is it just when showing particularly high or low?

I was told (at the Libre training):
- When the libre shows below 4
- When the libre shows above 13
- When my symptoms don't match what the libre says.
We know the libre is least accurate at very low and very high glucose levels (hence first 2 suggestions) and also that it lags behind your actual glucose level, so there was the tentative advice to do a finger prick when the arrow is straight up or straight down before doing any remedial action eg insulin corrections. Sometimes the straight up or straight down arrow is understandable so I don't finger prick just because it's there (eg if I've eaten within the half hour and it says its going up, but scan so I can drive).
We also know errors can occur so if the symptoms don't match your libre it is good to have a back up. There will be error margins with all devices (including finger prick devices) which is worth remembering.
I hope you enjoy it! I've loved having mine and it has helped me reduce spikes around eating in particular. The ability to use it to help pattern regulation is fantastic in my opinion!
Ah, in that case you'll have to find your own way. Same as I did when self fundingI mean that’s great but I haven’t seen and am unlikely to see a consultant any time soonalso self funding until able to
