Adding flags to the analytes Prerequisite: Ensure that the R Squared Value (Method) or R Squared Value rule is turned on to raise any exceptions. To add flags to the analytes: In the sidebar, click Analytes. On the Analytes page, select the Flagging tab. To raise an exception for an analyte, specify the R-squared value in the R2 Value column. Note: If you do not specify a value for R Squared Value (Method) on the Flagging tab, you will not see any exceptions for that analyte.
