I have been reviewing my sensor data from my 14 day Libre trial.
My Average Glucose on both the Libreview online portal & the Libre Link App was 4.6mmol/L
Yet they've used some weird algorithm called GMI to estimate my A1c as 5.3% or 34.
If I do an online conversion of my average glucose to A1c I come out with the much lower estimate of 4.5% or 26.
So I consult the Libre Link App which agrees with the conversion above.
I suppose what I must ask is what is this GMI & how accurate have others found it in relation to your lab A1c vs CGM A1c ?
