Hello catinahat,You could always invest in a glucose meter, the average from your own finger prick tests is probably more reliable than the HbA1c.
The HbA1c is not really an average, it measures how much glucose has got stuck to your blood cells in their lifetime. Blood cells tend to live for somewhere around 12 weeks, could be 9 weeks, could be 13 who knows.
My actual average blood sugar levels could be higher than yours, but if my blood cells kick the bucket at 10 weeks and yours hang around for 13, then I will probably have a lower HbA1c than you.
Thr HbA1c is a useful tool for Dr's to help with the diagnosis but for me, real time data from my glucose monitor gives me a far better understanding of how I'm doing and what my real average has been over any given period.
What is this place called? I live within 30mins drive from Guildford, so that would be useful for me.I use a private health clinic in Guildford to supplement the 6-monthly NHS tests. It is very slightly more expensive than Thriva and the sample is taken intravenously which I think may be more reliable than the finger-prick kits. I do regular fasting finger-prick tests anyway and have found that they correlate, on average, very accurately with the hba1c results and are an excellent predictor for them. But only the hba1c results will be recorded by my GP for the purpose of maintaining my remission Read coding in my records.
If you're prepared to pay private, you might find it cheaper to buy a glucose sensor and download the app. I think someone else has mentioned this possibility too. It may not be quite as accurate, but should give a reasonable indicator of bg average. The longer you use it the more accurate it will be, and may be useful in the long term. Also you can easily check bg at will. It also gives you daily patterns and averages etc. The two main choices in the UK are Libre or Dexcom. Libre works out about £25 per week.Hello,
Was diagnosed prediabetic in October (42mmol). I've made changes to my diet. The HBA1C test gives an average blood glucose for the last 2/3 months. The NHS will only do another test in a year's time. I'd like to do another test in January (about 3 months) to see if the diet changes have had any effect.
Looking on the web there are quite a few organisations who do these tests. Can anyone recommend a test provider?

The HbA1c test itself has an inherent accuracy of +/- 5% of reading. So even the same lab using the same blood sample can differ by 10% in the result. Changing labs may make this difference more pronounced. So be careful how you interpret the results since it may seem to give an improvement, but some of that change will be purely due to instrumentation error.Hello catinahat,
I'd been thinking that so I ordered one yesterday. I'm not sure I understand the relationship between blood glucose peaks and glycation rates. As I understand it glycation rate is a constant but how long/high a peak has to be to cause significant glycation I'm not sure, but avoiding and/or reducing BG peaks is important - so a monitor seems a useful tool. I'll still get a Hba1c done in January or February.
Thanks, I hadn't realised Hba1c readings could differ so much.The HbA1c test itself has an inherent accuracy of +/- 5% of reading.

I am glad to see you are intending to do some independant monitoring. Tracking results over a perod should show a trend if your diet is working. again the accuracy of a home tester is +/- 15% so you need to do some averaging of your own to see any worthwhile trend. Also home testers can throw wobblers and misread, so if it suddenly jumps out of line then it may be a misread, but equally could be giving a true value due to something you ate. Out of kilter readings need to be repeated to make sure the meter is reporting properly. But eating to meter is what many of us do, and the bonus is that we can use results to fine tune our dietary choices so long term there is a benefit to self testing.
Important that you wash your hands before taking the test. Contaminants on the site can give misreadings.
It is not so much, since it is 10% of a percentage so if HbA1c is 42 then error is +/- 0.25 mmol/Mol.Thanks, I hadn't realised Hba1c readings could differ so much.
Good point, I hadn't thought it through, assumed +/-2.1 mmol/MolIt is not so much, since it is 10% of a percentage so if HbA1c is 42 then error is +/- 0.25 mmol/Mol.
