Measurement – metabolites
The glucose or lactate concentration in a sample is calculated from the following
equation, using the difference between the current in the sample and the
extrapolated zero current from the rinse solution:



S
The measured value is applied a linear correction:

ckck
NOTICE: cLac is compensated for the dependence of the ionic composition by
using the measured electrolyte values before the linear correction is applied. If
the electrolytes are not measured, default values are used.
The following parameters are range checked:
 Sensitivity
 Sensitivity drift
 Sensor response stability
The sensor response stability is defined as the standard deviation of the last 5
updatings of the response for CAL 1 (rinse).
For CAL 3, it is defined as the standard deviation of a linear regression for the
last 5 samples, normalized with the signal magnitude.
