Slope Offset Adjustment
Introduction
The Slope Offset Adjustment option allows adjustment of the slope (m) or the y-intercept offset (b)
of the regression equation used for results calculations. Modifications are made on a per chemistry
basis. The default value for the slope is equal to "1" and the default value for offset is equal to "0."
IMPORTANT
Adjusting the slope and offset for a chemistry may result in a mismatch of normal range values
previously established.
