conversion chart

Hi everyone...I am sorry if what I am asking for is easily found, but I cannot find it lol Is there a conversion chart for readings/numbers?

My meter tells me my readings in numbers as in 6.5 or 7.0 etc but my hba1c result says 47 and i cannot find a conversion chart, the nurse said they like 48 so it is fine...but i want to know. If I find a chart I will copy it out..
 
Your meter reads something different to the HBA1c blood test so there is no direct conversion.
Your meter tells you how much glucose is in your blood now. The HBA1c tells you how much glucose is stuck to your haemoglobin. Haemoglobin "recycles" every 3 months or so so it can be used to approximate an average of your finger prick readings over that time (with a bit more weighting towards more recent) but, as you have seen your finger prick can vary quite a bit.
There are conversion tables for the average but, at best, they are estimates.

There's no direct correlation between finger pricks and HbA1c, but if you had 3 months worth of finger prick results it can give you a rough idea of where your HbA1c might be.

Bear in mind those finger pricks are only a moment in time so may miss a lot of highs or lows which will be reflected in your HBA1c.
Even the estimated HBA1c from a CGM (which takes a reading every 5 minutes), can be out by quite a long way.

(But I did spot your highlighted "rough idea" and "might be" 🙂 )
 
I have been mostly getting 6.5 to 7.0 on a regular testing basis....my daughter found a chart and 48 is 6.5 on it so my 47 is obv around there...which as their average from their test seems to fit my readings...

that was not my comment
 
HI @Myrtle_11 my HbA1c was 47 and also comes out at 6.5%. I don't bother trying to do the conversion although I did get a nice little card with my meter to show the conversion from mmol/l to mg/dL so event that doesn't really help.

Just a warning,
HbA1c used to be measured in percentages, and 6.5% equated to 48 in the new way of measuring, in mmol/mol. (it’s been used for a number of years now, but my test results still give it both ways, as a percentage and as a mmol/mol).
Blood Glucose meter readings are in mmol/L, and the figures tend to be in a similar region to the percentage HbA1cs , which is partly why the HbA1c system was changed, to avoid confusion.
If your daughter has found a conversion chart, make sure it isn’t just converting HbA1c in the old % system, (where 6.5% was the cut off point for diagnosis) to the new HbA1c mmol/mol system where 48 is the cut off point. That will have nothing to do with what your blood glucose meter is telling you.

My HbA1c was 47...with my meter i get 6.5 to 7.0 daily....48 is around 6.5 from what i have now read on this website, that will do for me, it gives me an idea where I am at.
Thank you for all replies to me. I just wanted to understand/make some sense of their numbers and mine. I know it all fluctuates constantly, it was just me trying to get my head around their result.

It is more helpful and you will avoid confusing yourself if you put the units with the numbers so your HbA1C is 47mmol/mol but your meter readings are 6.5-7.0 mmol/l.
They measure different things hence different units.
But 48mmol/mol units that is now used for HbA1C converts to 6.5% the old units for HbA1C and is only loosely related to your finger prick readings.
 
I found chart this handy.

Very good. I like it. My first HbA1c of 165 is off the chart (quite literally). Thank goodness it has come down since then. Still work in progress 😱🙄

I thought i was high initially 108 but 165 wow that's pretty high. At least you are making progress in getting that down.

If you look at the top row of the chart, your 48mmol/mol is the HbA1c. The 6.5 below is NOT the equivalent finger-prick reading, it is still the same HbA1c in the old units, 6.5%. Both are HbA1c.
The average of finger prick readings which would be very, very roughly the equivalent of this HbA1c is in the 4th row, and is 7.8mmol/L.
(Ignore the 3rd row, this is average finger prick readings in mg/dl, which is the units used in USA and Europe.)

So long as you are taking lots and lots of readings at different times of day, over many weeks, not just a few at just a few different times, if your fp readings are mostly 6.5 to 7 mmol/L, then you would expect a lower HbA1c of perhaps 39 to 42 mmol/mol.

Thank you... i saw that and realised...it has helped me get my head around it by being able to read that...the HbA1c was done a month ago but I only just got the result, so maybe the new meds have kicked in. I have been testing a few times a day during the month. Thank you for your reply.

Sounds like your results are pootling along nicely @Myrtle_11

If that keeps up, and if they have reduced since you’ve started on your new meds, you may well see that reflected in a slghtly lower HbA1c next time. It can take HbA1c a little while to change, which is why they don’t check it too frequently.

I have also ditched morning porridge :rofl: which was not helping me, mistakenly i was allowing too many carbs, reading on here i realised 130 daily was not the norm... if i get desperate for porridge i just have a very small portion but mostly just choose yoghurt now and a few berries. So that will have helped massively as i am now much lower carb intake in general. And i can see some day's reading's were affected by the day before and it took a day or two to get back down to what i had been getting, if that makes sense.
But if the nurse is happy with 47 for me, 7.8 for me, then i am very happy to be in range i seem to be 6.5 - 7.00...and that is down to all i have read here from you guys, so thank you. And now i have my chart :rofl: i have myhead around it more.
