Performance Characteristics

Precision: Precision describes the variation between
results. There are two types of precision results measured,
repeatability (using blood) and intermediate precision (using
control solution).
Repeatability: N=100
Mean (mmol/L) 2.4
SD (mmol/L)
%CV
Intermediate Precision: N=100
Mean (mmol/L) 2.1
SD (mmol/L)
%CV
System Accuracy: Diabetes experts have suggested that
95% of glucose meter results should agree within + 0.83
mmol/L of the medical laboratory values at glucose
concentrations below 5.55 mmol/L and within + 15% of
the medical laboratory values at glucose concentrations at
or above 5.55 mmol/L. The tables below show how often
healthcare professionals (HCP) and users achieve these goals
using capillary fingertip and forearm blood samples when
glucose results are not fluctuating. The laboratory reference
instrument is the Yellow Springs Instrument (YSI).
