A few weeks ago I was given a formula for calculating HbA1C from average BG levels. I have applied this formula for the past two months (see my sig block). I was advised, though, by a number of folk on here (thanks all), that this would probably not match my subsequent lab-tested HbA1C reading .. and sure enough, it didn't.
My calculated HbA1c for April was 36, and for May it was 33 .. but a lab-tested reading today was 40. This was taken on 18th but it is already on-line with all the numbers for my first annual review on 25th.
With this information, I have now re-jigged all the calculations I made when using the HbA1c conversion, partictularly to take in the previous 90 days worth of BG readings, rather than averages for the month .. and I can confirm that the formula is accurate but I made some errors in the averaging process. I was advised about this but still managed to get it (a bit) wrong .. so for anybody using the formula I would recommend double and even triple checking ..
Anyway, the bottom line is that my "actual" HbA1c is now sitting pretty at 40 .. and I'm a happy man
