Set the USE_STD_TARGET_FOR_PERCENT_DIFFERENCE Preference

Use this activity to set the USE_STD_TARGET_FOR_PERCENT_DIFFERENCE application preference to have the system use either the standard specification scheme version analyte's Expected Value, or the average of the standard lot specification scheme version analyte's Expected Value and the standard's analytical result (which is the sample scheme analyte's Final Numeric Value for a blank or standard QC sample or the sample scheme analyte's Final Numeric Value less the spike original sample scheme analyte's Final Numeric Value for a spike QC sample), in the calculation of the percent difference from the standard.

The Scope for this preference is usually set at user level.
