Hi everyone!
This is already 4th freestyle libre I am using and I always have the same problem. I the first 9 days my fasting is good, but last 5 days it's out of range. The difference is about 1 mmol/l. I don't change diet or my daily activity for the lat 5 days, so looks like the freestyle is lying, but when? In the first week of work or in the last 5 days ?
 
The only way to know is to check your Libre reading against a finger prick test.
 
Thank you. I have gdm, used only freestyle libre and never finger prick. I have read that margin error in freestyle is about 9% and finger prick tests from 5 to 10%. Could you advice the good one?
