System accuracy

The GL42 blood glucose monitor in comparison with the YSI.

Three lots of GL42 blood glucose test strips have been tested to assess the system accuracy of the

GL42 blood glucose measuring system and to compare it with the reference method in which capil-

lary whole blood concentrations of 24.8 to 715 mg/dL have been used.

In comparison to the YSI, the GL42 met the EN ISO 15197:2013 standard, whereby 95% of the blood

glucose values measured have to fall within the following zones: either ±0.83 mmol/L (±15 mg/dL) of

the measured average value when using the reference measuring procedure for blood glucose con-

centrations <100 mg/dL (<5.55 mmol/L) or ±15% for blood glucose concentrations of ≥100 mg/dL

(≥5.55 mmol/L). 99% of the individual measured blood glucose values must fall within zones A and

B of the Consensus Error Grid (CEG) for diabetes type 1.
