[QUOTE="Nicole T, post: 2320222, member: 527609"] Chances are that neither is absolutely correct. That seems to be the nature of blood glucose testing: we have a choice of various random number generators, each roughly centred around what our blood sugar actually is. A quick Google shows an error allowance of 0.5% on the HbA1c blood test. Presumably that's actual percentage points where the result is given as a percentage. So if I'm interpreting that correctly, that means your 7.2% could indicate anything from 6.7% to 7.7%. Meanwhile, the Libre is allowed to over or under read by as much as 20% on any individual reading. While I would expect those to average out to some degree all of the time, that would still place your Libre predicted A1c in the range 4.96% to 7.44% [/QUOTE]
