* The Xylose was higher than 0.55 mmol/L in interval 1. After
conduction dose-response testing for Xylose, the maximum
interferent concentration in interval 1 was calculated as 0.54
mmol/L
User Performance Evaluation
A study evaluating glucose values from fingertip capillary blood
samples obtained by 100 lay persons showed the following
results:
100% within ± 0.83 mmol/L of the medical laboratory values at
glucose concentrations below 5.55 mmol/L, and 100% within
±15% of the medical laboratory values at glucose concentrations
at or above 5.55 mmol/L.
