Freestyle Libre - Contour Next testing

[mike watson]

Hi,
I've just switched from good old blood test strips (Contour Next) to the Freestyle Libre kit, I'm still checking with blood tests but am getting blood test results consistently 1 mml (roughly) below the Libre readings on the sensor. I know there is the possibilty of a timing difference but this seems unrelated.
Has anyone else had this? Who do I believe?

You’d get the same variance with different fingers on blood testing. Neither system is completely accurate, there’s a natural variance, so your readings are essentially the same.

And yes, most of us Libristas find the same thing🙂

You'd also get different readings with a different branch of test strips and meter. 1 is close enough that if you had some really accurate way of measuring (which we don't) it wouldn't change what you do.
