hba1c results

[mark1985]

hi
My hba1c was 100mmol/mol and 11.3% how can i work out when doing my bs finger pricks if i am improving this or not. When the dn tested my bs it was 13 im now getting it down more to between 8 and 12. Is there a table or sum i can do to work things out at all?

There is no direct correlation between blood glucose levels and HbA1c that I can see in myself.
I got down to HbA1c of 41 eating no more than 50gm of carbs a day, when it went up to 42 I decided to reduce to no more than 40gm, and a year later my HbA1c was - 42.
I could see my after meal numbers were down a bit - but perhaps as my age increased my breaking down and renewal of red blood corpuscles reduced in frequency so they are testing older stock.

I found that with a continuous glucose monitor on my arm it would predict the HbA1c level from 14 days of glucose readings that was close to the actual last time it was tested (August). HbA1c by definition is an average of longer term blood glucose so any individual finger reading is not going to be of use.

hi looks like i was getting confused with the uk and american conventions of readings have found a calutator now which has helped a lot.

You shouldn’t need to convert between American and uk readings. That hba1c of 100 isn’t an American reading it’s just a different system of reading that can’t be compared to fingerpricks.

What American results are you converting and why?

its the blood suger results i needed to understand as looking at some tables they were in mg/dl not mmol/l

What tables are you looking at? Best sticking to UK websites.

There isn’t really a way to convert average fingerstick glucose readings to HbA1c with any accuracy unfortunately @mark1985 .

You can use one of several formulae derived from empirical pairs of average BG vs HbA1c, but it’ll still only be a rough approximation.

The Dexcom one is:

GMI mmol/mol = (4.70587 x BGAverage mmol/L) + 12.71

They deliberately call it GMI (Glucose Management Indicator) to make it clear it’s not a direct conversion to HbA1c.
