2.7.4 Linearity
Linearity was determined by running diluted samples. Samples of different concentrations were
tested in both whole blood and pre-dilute modes; the slope and intercept were calculated per the
linear regression equation, and then the deviation between the theoretical value and test result was
obtained, which shall meet the requirements in the following table.
