Figure 62. Standard Curve Report.
Features of the Standard Curve Display
For replicate groups of standards, bars are plotted on the graph at each point
corresponding to the standard deviation for the group.
The Standard Curve Report displays curves for both internal and external
standards. Internal standards are displayed in red, external in blue. If both have been
defined for an assay, both will be displayed in the curve window; however, only the
external standards will be used to calculate unknown concentrations. See page 73 for
information on defining external standards. See page 86 for information on validating
external standards.
The equation of the curve is displayed at the bottom of the window. This equation is
determined by the standards data, the Regression Type selection, and the
Transformation selection (see the following sections).
