BG and HbAC1 measurement

My home test kit (SD code free) results are based on full blood samples. How does this compare to lab test results which I believe are based on plasma samples?


The GP says that my HbAC1 reading at 48% is just on the threshold of being diabetic. How does that figure relate to the x.y (for example 6.4) figures that I see on this website. WHOOPS!! I have this the wrong way around and now see that 48 mmol/mol is equivalent to 6.5% (OLD STYLE) Query withdrawn.

lab results arent on plasma samples, they are testing the haemoglobin sugar content. there is a conversion chart on the site.
 
At one time home blood glucose test meters measured glucose levels from a FULL or WHOLE blood sample and confusion reigned as it still does to some extent.
My home B/G meter has a setting that approximate any reading to either a FULL blood or WHOLE blood sample as well as what it calculates as being a PLASMA equivalent of having a proper Blood test done in the LAB where the blood sample is separated into the Haematocrit and Plasma compounds by them spinning the sample in a centrifuge before analysis. This is not to be confused with the HbA1c or Frutosime test readings which are both something completely different and indicate average Blood Glucose levels over a set time period of several weeks .
Modern Home Blood Glucose testing meters, though they still obviously use the FULL or WHOLE blood sample blood from the finger prick, use a different technology to indicate the final result, measuring the conduction that occurs over two electrodes within the test strip. Yet again the result is computed and is therefore something of a compromise.
Ultimately the truly only accurate way is to have the blood sample tested at the Laboratory, but even with the limitation on most home B/G meters reasonably accurate results that are comparable can still be obtained.

I hope no offence was caused. I did smile. So sorry I don't have the requisite knowledge to contribute to the thread in a sensible way. Thank you for your post @Lazybones, I have learnt from it.
