System accuracy

The GL50 evo blood glucose monitor in comparison with the YSI.

Three lots of GL50 evo blood glucose test strips have been tested to assess the system accuracy of

the GL50 evo blood glucose measuring system and to compare it with the reference method in which

capillary whole blood concentrations of 34.4 to 442.8 mg/dL have been used.
