Figure 2.
Accuracy of glucose results on Accu-Chek Instant under optimal conditions. The x-axis represents the mean glucose
result of the comparison method. The y-axis represents the glucose deviation in mmol/L of the first capillary measurement on
Accu-Chek Instant from the mean result of the corresponding sample of the comparison method. The different lots of test
strips are illustrated as lot a (
•
), lot b (
◆
) and lot c ( ). Stippled lines represent allowable deviation limits set in ISO
15197:2013 (within ±0,83 mmol/L of the results of the comparison method for glucose concentrations <5,55 mmol/L and wit-
hin ±15 % for glucose concentrations ≥5,55 mmol/L). Number of results (n) = 85. ID 32, statistical outlier from the calcula-
tions of repeatability (lot c), is illustrated with a circle around the symbol.
Figure 3.
Accuracy of glucose results on Accu-Chek Instant achieved by intended users (three lots of test strips). The x-axis
represents the mean glucose result of the comparison method. The y-axis represents the glucose deviation in mmol/L of the
first capillary measurement on Accu-Chek Instant from the mean result of the corresponding sample of the comparison
method. Stippled lines represent allowable deviation limits set in ISO 15197:2013 (within ±0,83 mmol/L of the results of the
comparison method for glucose concentrations <5,55 mmol/L and within ±15 % for glucose concentrations ≥5,55 mmol/L).
Number of results (n) = 85. ID 80, statistical outlier from the calculations of repeatability, is illustrated with a circle around
the symbol.
