CGM readings

[Sadsac@21]

I use the Libre 2 plus and thought that the readings had been fairly accurate when I used the Libre 2. Since using the upgraded one however my readings are so much higher. When I got up this morning CGM reading was 8.7, finger prick was 6.1. Tonight when I got home from work my CGM was showing at 7.3 finger prick was 5.5. Is this right? I have been trying for the last two weeks to figure out what I was suddenly doing wrong to be getting higher readings than normal, but this has only started happening since using the Libre 2 plus.

Unfortunately cgms can read "off" . Is this all on one sensor or over 2 or more? If the latter you might want to investigate additional software to allow you to calibrate your libre...

I'm going to tag @Antje77 who I believe uses diabox .

Thanks for the tag @EllieM .

Yes, I use DiaBox to be able to calibrate, my Libres always read lower than a fingerprick. I always trust a fingerprick over sensor.
I'm also much happier with the options for alarms on DiaBox as compared to the official Libre app.
However, I'm on the Libre 2, not the 2+, it's not available in the Netherlands.
