Configure Calculation Options for Analysis Codes

For context, see Configure Analysis Codes Options.

Activity Steps

  1. On the Profile ribbon tab, click Analysis Code.

    The Analysis Codes screen displays.

  2. Select the Analysis Code.
  3. On the menu, click Setup » Options.

    The Edit Analysis Code screen displays in the Client Job Options category group.

  4. In the Category list, click Calculation Options.

    The Calculation Options screen displays.

    Note: By default, when a sample has replicates, AssayNet LIMS averages the values to calculate and report a single final result for the client sample or QC material. This is the option commonly used in most operations, but you can modify the options as required.
    1. In the first quadrant, select whether to modify the calculation at the Sample or Analysis level. Generally, the same calculation is performed at both levels.
      1. In the Calculation field, select from:
        • Average—(Default) Averages the replicates for the selected sample type.
        • First—The first result is always selected.
        • Maximum—Selects the maximum result among the replicates.
        • Minimum—Selects the minimum result among the replicates.
        • Standard Deviation—Calculates the standard deviation of the replicates.
        • Sum—Sums all the replicates for the selected sample type.

        Note: The calculations apply to all the samples and analyte schemes assigned to the analysis code. If you need to modify the calculation for a particular sample or analyte scheme, you must do so in the analyte scheme formula. For more information, see Configure Calculated Analyte Schemes.

      2. Set Weighting to Yes (default option) or No to specify whether or not the calculations are based on weighted components.
    2. In the second quadrant complete the following fields as required:
      • Dilution Affects Precision—Includes the dilution factor in precision calculations. Useful when variations in dilution impact result accuracy.
      • Initial Measurement Affects Precision—Takes the initial sample measurement into account when calculating precision.
      • Final Measurement Affects Precision—Takes the final measurement (for example, volume) into account when calculating result precision.
      • Use Results on Hold in Calculations—Allows results flagged as on hold to be included in calculations.
      • Enable Custom Calculations—Enables use of a stored procedure for customized result calculations. If selected, enter the Procedure Name.
      • Return Calculated Results after Data Entry—Displays calculated results immediately to the right of the entered data upon completion of data entry in the Data screen of the Instrument Run page.
      • Auto-Hold Flagged Results—Automatically flags results that meet the defined criteria. For more information, see Add and Configure Packages.
      • No Prep QC—Disables preparation QC validation checks for this analysis.
    3. In the Auto Calculate category group, select from:
      • Off—(Default) Results are calculated only when you click Update in the Result Summary screen. For more information, see View and Approve Results.
      • When Run is Created—Results are calculated after the run is created.
      • After Data Import—Results are calculated after the data is imported, displaying the final result beside the column for the entered or imported value. For more information, see Import Instrument Run Data.

    4. In the Auto Approve category group, select from:

      • Off—(Default) Results are approved manually. For more information, see View and Approve Results.
      • When Run is Created—Results are approved after the run is created.
      • After Data Import—Results are approved after the data is imported. For more information, see Import Instrument Run Data.
    5. In the table, select whether each QC sample type is Formatted or Unformatted. Generally all types are set to Formatted.

      Note: Formatted (default) results for QC types display with the proper decimal places and detection limit symbols.

  5. Click OK.
