I know that you can get an estimated HbA1c reading on the mysugr app, but I don't have a smartphone.
Blood glucose meters can give your average bg readings over the previous 7, 14, 30 and 90 days.
I checked mine today, and my 90 day average is 6.6 mmol/L. I know that won't give an accurate HbA1c forecast, but it would be 39.5 if it did. I am expecting something more in the high 40s.
So what is your average bg reading over the last 90 days, and what would be the equivalent HbA1c reading?

You can convert the mmol/L reading to HbA1c (ifcc) here:
https://www.diabetes.co.uk/hba1c-to-blood-sugar-level-converter.html
 
My 3 month average from my meter is 6.7 which equates to 40.5, mysugr app is 39.6, but my latest HbA1c result was 45. So, it's not completely accurate. My readings have been higher recently, don't know why but hopefully it will settle down soon.
 
I have a cheap one touch ultra 2 and use the cheapest GenUltimate strips.Only does 30 days .

It said I would be a 5.5 using the conversion from fingerstick to HbA1c chart,actual lab result came in at 5.4.Surprisingly accurate.

Sorry,USA numbers and its late night 0230 AM here and Im too braindead to convert those,but you get the drift.
 
I have measured this several times over the last two years on around 6 devices, and my combined measurements are always circa 4.3 or 4.4 mmol/L, which is why I know I have some discordance going on.
 
My average for the last 90 days is 5.7 this according to the on site convertor would equate to 33.3 roughly what mysugr app is saying.

My last HbA1c was a higher than that but that was in February.
 
My current 90 day average on my meter says 5.2 which makes an HbA1c of 29.8 using this converter:
https://www.diabetes.co.uk/hba1c-to-blood-sugar-level-converter.html MySugr is currently saying 29.3 so pretty close. However I know from comparing MySugr to lab results in the past that the lab result is usually higher. MySugr was reading 29.4 when I had my last lab result which was 34. However I never take any of these estimates as absolute but use them to watch for trends
 
I am no longer testing with finger pricks apart from morning fasting levels, and not even that when I wear a Libre.
However, from previous averages that I have obsessively recorded, my 90 day averages were always mid 5s when testing multiple times a day. Highest was 5.7. On my current Libre, due to finish later today, my 2 week average is 5.6., which would equate to an HbA1c of 32.6. This is why I have an issue with my HbA1c lab tests because they are always in the low 40's, usually 10 points higher than I would expect. I now ignore my lab results as much as it is possible to do.
 
Well, my last pre-insulin Hba1c was 6.5%. My Libre suggests 6% and Glimp 5.6%. I think as both overread, based on my finger-prick blood tests, it will be lower. Excited. Can't wait until the 12th of September, three months after the last blood test.
 
Hi @Prem51

today My codefree at 5.9 (est hba1c 35 ) ( codefree 30 days only)
Mysgar puts me at 6.1 ..(est hba1c 37] 90 days
and recent HBA1c sits me at 6.6 (Actual hba1c 40) mid july

so while not madly spot on, keeps me in my safety corridor.

My three month average is 5.62 mmol/l which will in theory give me a hba1c of 32.7 mmol/mol using a Abbott Freedom Lite meter.

Using the convertor that @Prem51 linked to:

Convert Average Blood Glucose Level to HbA1c

Enter average blood glucose level: 5.62 mmol/L

YOUR ESTIMATED HBA1C RESULTS 5.1 DCCT - % or 32.7 IFCC - mmol/mol

HbA1c under 48mmol/mol (6.5%) can help reduce your complications risk.

Next hba1c is due begining of September.

Edit: Fix wrong tag.

I've used the Diabetes.co.uk converter for a while now and have found it consistently gives a slightly lower result than my actual HbA1C.

3 months average from Contour Next meter was 6.9 -> predicted conversion to HbA1C of 41.5, so my actual lab result will be closer to 43. Which is better than anticipated, due to a rather stressful year resulting in a bit of naughty eating on occasions, and I've seen some rather too high readings...

(When I was using the Libre sensors, predicted HbA1Cs were always around mid 30s, so were way out! )

I tend to be fairly accurate in my non meter and converter guestimates, because since I've been low carbing my results don't change much unless I'm ill ,in pain, or stressed out.

That example of mine is down on my lhba1c which have been on 34 mmol/mol for a fair while now.

Begining of September I will have another hba1c at the pathology shop, I will compare my 90 day average again with the convertor and what the pathology shop result is.
 
My meter put me at around a 4.8 at 90 days and my latest HBA1C was 29 which is an average of 5.0 so I am rather satisfied at that accuracy.
 
I have to add that the results that I take most heed of are those from my meter, as I'm seeing actual "real time" levels for fasting, pre and post meals, etc, and their individual averages over various periods, and not a single lumped together average from my 3 or (more usually now) 6 monthly HbA1Cs which may be fine for keeping track for my diabetes reviews, but tell me nothing particularly useful regarding how I'm managing my glucose levels and diet.

PS Slightly off at a tangent, but it always makes me go EEEK !!: my GP always likes to proudly show me my HbA1c graphs, but on his monitor they appear as horrendous jaggy spikes and troughs (due to a squidged up time line) but in actual fact they've varied very little over my diabetic lifetime.

The one I have in my sig is done in a android app called Sugar Diary, it is spaced out abit over three years from the big speed bump. The bit before the bump is from when I was diagnosed T2 five years ago.

I give my GP minimal printouts from the Abbot meter software, just a months worth of bgl logbook, a couple of other charts / graphs. He is happy with that, I'm happy as he will sign of on subsidised strips @ $1.20 for 100 strips for another six months.

Sorry cant participate I never check mine.

I check mine occasionally, usually FBS or when I’ve eaten something overly carby so probably don’t have enough data to prove/disprove the difference between meter and hba1c.
 

Snap. I always kept obsessive records and average each individual type of reading (fasting, bedtime, before each meal, after each meal (at various times after eating). That way I kept track of how I was doing fasting, before meals and rises/peaks after meals etc. Lumping them all together can be "dangerous" in that we may have more data from times when we are normally low than times when we are normally higher. What it does not take into account is the length of time we are low and the length of time we are higher. This is the fallacy of average - much like the HbA1c can be.

Every check I've ever had the numbers went down, so I figured I was doing something right.

Haven't been proved wrong yet.
