Hi!
Now I'm not talking about trying to get my finger prick to match my scan, as they are measuring different things that respond at different times etc etc
BUT the difference between my Libreview HBA1C and the hospital blood test has been consistently very different, latest being 32 vs 44.
The higher number is the blood test obviously! This equates to approximately 1mmol/l difference in all my readings on average.
Has anyone else made this comparison?
Obviously there are several factors to consider...
1, blood glucose meters are not 100% accurate
2, Libre is not accurate
3, most software like libreview only estimate hba1c over a short period, my last discussion with the consultant told me not to trust the libre view or decom clarity for this reason, more use it as an indication of whether the results are going up or down
4, hba1c results also have a margin of error, i know someone had 2 hba1c in different labs in 1 day and had differing results
these for factors above alone could make quite a difference in the hba1c results
i use the dexcom which I find much more accurate than the libre, and i run it through night scout which the reporter is quite good over a 3 month period.. my estimated hba1c was 51, actual was 47.. so i can imagine the libre being slightly further out than that.
either way the hba1c is still good, and im sure the libre has helped you achieve that... and as time goes by you'll manage better in what to expect from the libre.. and hopefully when the libre 3 comes it will be slightly more accurate as they are aiming for iCGM approval
