What is it about?
Mean Absolute Relative (percent) Difference between a self-monitoring blood glucose (SMBG) meter and laboratory instruments is a way of quantifying SMBG error. The ISO 15197:2013 has a different measure of error. The relationship between these two measures is not simple, but it can be quantified in a probabilistic sense. This paper describes a probabilistic model that describes the relationship, under certain given assumptions.

Why is it important?
It is important to recognize the limitations of using MARD as the single measure of analytic performance for SMBG meters. This paper gives some potential guidelines for using MARD to evaluate SMBGs, along with a description of the limitations.
