Any thoughts on how accurate is Freestyle Libre ? My current CGM reading is 4.5 so I've tested with a finger prick via my Caresens and it's showing 7.7 !

Both can be within 20% up or down
Also libre doesn’t measure blood, so it’s readings can be about 10 minutes behind so if at a time of rising or falling can be different
Also dehydration can cause false lows, and finger contamination and soap can cause false heights with a bg meter
Typically you should trust the bg meter as these are considered more accurate and reliable, and if you have any unexpected readings you can try another test just to be sure
