Type 2 Meter averages

Unless you are taking readings throughout the day AND night, you are unlikely to get a good average over the period your Hb1AC is measured.

If a meter average correctly estimates an HbA1c, it is a lucky coincidence.

The HbA1c is an average over 2 to 3 months of your glucose levels 24/7. Your meter averages can never catch your levels between tests. You may see 7.8 at 2 hours post meal - but was that on the way up, on the way down from a much higher number, or were you 7.8 for several hours? You can't possibly know.

My advice is to stop worrying about HbA1c results and concentrate on getting your meter averages down from 8.6.

Hi @Philb69 ..
You might find the details of this HbA1c to blood sugar converter helpful. As others have said above, it's pretty useless for a single blood sugar reading but what I did was to keep all my readings (3 to 5 a day - fasting, pre-meal and post-meal) on a spreadsheet each month .. then averaged each category for each month .. then averaged the averages over a three month period .. then put this figure into the converter. I have done this twice now in late June and late August, just before my 3-monthly reviews and the results were ..
June .. HbA1c calculated - 41 : actual - 40
Aug .. HbA1c calculated - 35 : actual - 34

Having said that, I agree with @Bluetit1802 that you should focus on bringing your blood sugar levels down and with @No2D that your diet and lifestyle is more important than chasing numbers.

Hope this helps

An average of 8.6 is likely to mean you are spiking too high after meals, and these spikes may be causing you damage. The NICE recommendations for T2s is an HbA1c of 48 or less (this has been reduced from 53 during my time as a diabetic). NICE blood sugar level recommendations are known for their generosity, so 48 is probably generous. 48 is an average of 7.7mmol/l.

I consider (for the time being, anyway) that HbbA1c and daily readings to be two different entities. I made a lot of mistakes in the first few weeks after dx while learning about the food carb counts so at the moment I concentrate on getting into the habit of checking and recording everything. It is becoming easier but I still have wobbles and so I still need to work on discipline and learning the ropes.
Later, when my HbA1c approaches acceptable levels I will be able to go deeper into the cause and effect of carbs on the body but for now I am putting all my efforts into reducing the amount of carbs I ingest, everything else can wait.

I'm currently putting my readings into the MySugr app. Once you have put in sufficient readings it gives an estimated HbA1c. I have my review in a couple of weeks, it'll be interesting to see how accurate it is.

I do the same as AM1874. I will do comprehensive testing, Fasting, pre and post prandial and before bed. I downloaded a HbA1c converter off the net, it is in spreadsheet form and as you add your readings it calculates your expected HbA1c result. It has always been accurate but the key is making sure you take your readings throughout the day otherwise there's no point.

@Rachox it will be interesting to see how accurate the MySugr app is, please let us know.

I will! I usually test the same times as you, though getting up later during the summer holidays my fasting and pre-breakfast have become one! That still makes 7 readings a day instead of 8.
