[QUOTE="UK T1, post: 2250843, member: 503751"] I think I've been fortunate with my libre sensors so far, but have loved having it! It is worth remembering (as said above) that all sensors and all finger prick/capillary glucose monitors can be off. So in theory the sensor could have been at the bottom of its error range while your meter maybe was at the top of its error range? I think that's what was suggested above. It also of course if possible that you were a bit lower and released glycogen/glucose to bring it back up. When my sensor and meter don't correlate I set an alarm to scan 5/10/15 mins after I've tested to try and see for my own peace of mind whether they do now agree a bit better. Of course a new sensor and a new batch of glucose testing strips will have a different tolerance and so possibly different readings, which doesn't make this easy! It does always surprise me how quickly my warning symptoms can kick in at different thresholds. Eg one week I'll feel awful if my bloods are at 8/9, but if I let them stay there it only takes a few days for my body to assume this is the new norm and feel fine at those levels, and suddenly feel hypo-ey (technical term ;) ) at 5ish. Has it only happened twice? Same sensor/batch of strips? [/QUOTE]
