Is Hba1c related to the averages in blood glucose diaries

Hi all,

I am new here and only been diagnosed 2 months ago. I wondered if anyone knew if the averages displayed in our blood glucose diaries may be an indicator of Hba1c results

Thanks

Michelle

Not exactly unfortunately.

The averages we see on the diary are those of the results you've inputted on to the diary. Your HbA1c results read the results of how much sugar has been in your blood by reading the red blood cells themselves (they only live for 3 months though), so the diary averages may not be a reliable indication of your HbA1c as a result - especially if you're someone who has irratic control.

Saying that, I've found that when the BG levels are consistantly within a range over a long period on the diary, it has shown up in my HbA1c test to be around the same. I guess that's just a good sign that I do keep myself stable I suppose.

Oh,

Thank you!, I guess it's just as you say, trying to keep them as stable as possible!. Mind you a y reduction would be fab for myself co sideri g it was 125 mol/mol at diagnosis

Welcome michdash
As JWO mentions stability counts. Make slow controlled changes and you can understand where improvement comes from.
Stick with it and in 4 or 5 months you'll be at 58 mmol/mol and looking for further gains.

Thanks Garry,

Yes this is indeed a life changing experience, however I am learning more each day. Thanks for the advice

If you still get the old % figure (we get both here in AU) I know you can calculate it by taking your HbA1c % double it then minus 6 from the result, will convert it to average BS we read off the meters.

eg me now 6.4hbA1c x 2 -6 = 6.8 - Which equates nicely with my diary.
me last Nov 10.5hbA1c x 2 - 6 =15 - GP kicked my arse, told me to fix myself pronto

Wow - Rich!, that's a high one!..but at least it's decreased nicely now

Thank you, after diagnosis where my hba1c was 125 2 months ago I had another test just before dafne two weeks ago which was 95 that equals around 10.5 as your previous result so it's coming down slowly. Fingers crossed for sept test

Cheers Guys

Wow, I had no idea you could do that Rich! Thanks for sharing!

Gleaned it from a magazine article early this year. I actually took it up with me to the DAFNE course to confirm. The 'professor' actually knew the author of the article and did not doubt the simple formula would give a reasonable estimate of average.

The formula I use to estimate HbA1c is HbA1c = 90Day Average + 2.52 / 1.583.............

Can I explain why its that? No?

But its online somewhere and came from a study...........

It has never been bang on for me though, I suppose it never can be........
