Libre2versus libre3

[Clarelryxx]

Hi I’m currently using libre 2 but finding readings are way out compared to finger prick testing I do know they lag behind but reading s can be massively out spoken to my diabetic nurse today and can change to libre3 or dexcom 1 just wanted some feedback as dexcom don’t send alerts when phone is on silent mode if anyone can give advice it would be appreciated thanks

I do not know about Libre 3 but, whilst there is a delay in interstitial fluid readings, Libre accommodates this so should not be obvious in the readings.
I assume Libre 3 will use the same algorithm.

Dexcom 1 is a 'flash' glucose reader much like Libre 2. Libre 3 however, is much more a 'real' CGM and not normally freely available on demand to all T1s.

Dexcom 1 is a 'flash' glucose reader much like Libre 2.

But it's an rtCGM rather than an isCGM (it does not need to be scanned like Libre 2 does).

(As I understand it it lacks some features present in G6 (no calibration, no predictive alarms, can only connect to one device at a time (so can't be used for pump control), but is basically a simplified G6 (likely produced because Dexcom wanted something to compete with Libre).)

Everything I have read about Dexcom one suggests it is not a flash CGM.
It uses Bluetooth to transmit data rather than needing to scan the sensor with NFC.
Unless I misunderstand what you mean by "flash"

I doubt flash is a useful term to use. I suspect it was used to emphasise that Libre sensors themselves recorded (on flash memory) 8 hours of readings (which was then read by scanning), but I suspect it wasn't a great way of describing things (because it's a description of something that really doesn't matter much to users).

In terms of understanding their use, I think the terms rtCGM and isCGM are much more useful.

Well yes, but I just couldn't remember the correct terminology 😱

Depending on whether the alerts have been deliberately nobbled, my G6 can and does alarm when my phone is on silent - which it always is.

Might be worth calling Dexcom to ask them directly @Clarelryxx ? Seems an odd thing to have disabled??
