Blood Glucose Converter & HbA1c Tests

Last night at Warrington, it came up once again that we’re sometimes working with different blood glucose figures.

So, here are a couple of  links, with a handy blood glucose converter and a table:

The table:

Basically, the old measurements, that we still often use where I live in South Lakeland, are percentages and the new measurement is the IFCC unit of mmol/mol.

So you all know, an unmedicated HbA1c which is sub-6.0 in old money or 42 in mmol/mol is ‘normal’ and non-diabetic. Anything between 6.0 and 43 mmol/mol and 6.5 and 48 is pre-diabetic and anything above 6.5 or 48 mmol/mol is diabetic.

Now, don’t get your HbA1c and your daily blood glucose readings mixed up, as I did when I started testing. When on my low carb reversal diet, I’d sometimes get a reading of say 7.5 after a meal. Well, if you’ve just eaten an hour before, of course your blood glucose will be higher and in fact if it’s under 8.0 or 64 mol/mol, that’s perfectly OK. If it’s higher than that, it’s worth taking a long look at what was in your meal and start trying to work out what might be pushing your blood glucose up.

The reason a HbA1c is a good test is that it gives you a really clear idea of what your blood glucose has been doing over a three month period. Unless you test yourself multiple times a day, you might not be able to get as good picture as an HbA1c test and so it remains the single best way of getting a picture of your overall health.

Even after you’ve reversed your T2D, I recommend getting a periodic HbA1c done and I’ll be getting on done in January, a year on from my last one. You should also continue to get retinopathy screenings done after reversal, at least for a time, as retinopathy can sometimes continue but will tend to improve over time, as will neuropathy, as they are essentially different manifestations of too much sugar in the blood.

I hope this is useful and speak again soon!
