By the way, I'm a Type 2 on insulin but the nurse won't prescribe a cgm for me. I wonder if different areas of the country have different rules?

The more I read members varying experiences with Libre s accuracy the more I think our bodies vary considerably in how fast or how quickly glucose finds its way into the interstitial fluid or even how our body reacts to the filament penetrating our skin.

My own experiences with Libra is the same as yours @ChrisT2 . My Libre values are always lower than my finger prick figures, even given Libra's lag in glucose readings, but only around the 'normal range' . Outside of that range the accuracy of the Libre diminishes. Interestingly, my finger prick device's readings were lower than the pharmacy device when I asked them to compare my device with theirs. Of course, we have to consider the allowable error of 15%+/-. Only the lab device, which I presume is calibrated to higher level of accuracy.

We miss so much with the standard before and two hours after a meal. The highs and the lows between those figures.

Also my estimated Libre HbA1c is always lower , sometimes the difference is significant, than the lab run HbA1c results.

Thank you all very much for your replies. I am going on one dose of insulin per night at the moment and we’ll take it from there so I can’t get the libre prescribed unless I go on to need at least one more dose per day but I think I’ll self fund another couple and use them as educators. You’ve all given me some great advice here and I’m very grateful to you
