Message: <blockquote data-quote="giorgoXXI" data-source="post: 2583833" data-attributes="member: 568383">The Freestyle Libre readings are usually around 20 mins behind your actual blood readings. So if your finger prick was 10.1, around 20 minutes later your Libre should have said you were approximately 10.1 also.If you still see a big difference even accounting for that 20 minute difference, it is quite possible your Libre 2 is faulty (which happens often). Simply contact Abbot, they'll probably want 3 different samples of reading discrepancies between your finger prick and the Libre, and they will send you a new one.Remember even your finger prick reader has a 15% accuracy range, none of the numbers are actually fully accurate. The Libre 2 is great to see trends and spikes rather than relying on it for absolute numbers, but it shouldn't be so inaccurate as you are describing.</blockquote>
