User Performance Evaluation
A study evaluating glucose values from fingertip capillary blood
samples obtained by 100 lay persons showed the following
results:
100% within ±15 mg/dL(± 0.83 mmol/L) of the medical
laboratory values at glucose concentrations below
100 mg/dL(5.55 mmol/L), and 100% within ±15% of the
medical laboratory values at glucose concentrations at or
above 100 mg/dL(5.55 mmol/L).
