conversion to mmol

Hello, just realised after reading another post that 42 hbac1

Hello ,I have been asked by a relative what 42 in Hbac1 prediabetic terms equals in mmol in the blood sugar count is?

An average 7 mmol/l.

Thanks Bruce ,wish they would stay with one way of testing.

They're different measures for different purposes. I usually want to know what my BG is now (so I can make immediate decisions on what to do), and a test strip gives me that. Sometimes it's useful to know what the average has been and that's what HbA1c gives (presuming it's not being influenced by the various non-BG things that can influence it).

(I agree there's not much value in having multiple units for BG and HbA1c. Those are just annoying. HbA1c of 42 mmol/mol is 6% in the older units, BTW.)

I believe the reason for changing the units from % to mmol/mol was because people got confused between HbA1C as % and spot tests from a finger prick even though the units were mmol/l as the actual numbers were very similar.

Thanks Bruce ,B G is blood glucose ?

Yes. (So the value from, for example, a test strip.) There's a relationship between HbA1c and estimated average BG: https://ngsp.org/A1ceAG.asp

I should say a typical test strip that we use for blood glucose. There exist test strips (and machines) for HbA1c. (And other things like ketones.)

Yup, it’s not really possibly to directly convert one to the other, because one is a spot-check of one moment in time, and the other is the effect of circulating glucose on red blood cells over the past 3-4 months.

But the average fingerstick glucose conversions can give a rough idea. 🙂
