Why we should look at TIME in RANGE as the new metric rather than HBA1c – the  latter gives a mean average across 3 months whereas the former reflects the most frequently occurring blood sugars (the modal average) thus avoiding the rollercoaster effect of lows and highs which can be concealed by an HBA1c.   But.. if type 1s are to achieve better time in range results then we will need access to effective continuous glucose monitoring which is currently unaffordable in Surrey for the average diabetic.
