Abstract
An improved test cassette for the integrated Accu-Chek® Mobile system (Roche Diabetes Care GmbH, Mannheim, Germany) has been developed. System accuracy of this improved system was evaluated based on ISO 15197:2013, clause 6.3, for three reagent system lots. According to this standard, at least 95% of the system's measurement results shall be within ±15 mg/dL and ±15% of the results of the comparison method at glucose concentrations <100 mg/dL and ≥100 mg/dL (accuracy criterion A), respectively, and at least 99% of results shall be within consensus error grid zones A and B (accuracy criterion B). In addition, accuracy was evaluated in the hands of users based on ISO 15197:2013, clause 8, with one reagent system lot.
