Analysing QC Performance

Overview

Various aspects of the QC performance analysis environment can be configured by the LIMS administrator to limit access, fix the type of data expected, and to customise the spreadsheet.

This process is pertinent to LIMS and laboratory managers who configure the LIMS and quality control (QC) performance analysis sessions, in particular.

Process

Configuring Access to the QC Analysis Application

Ensure the Perfana.exe file is located in the folder defined by the ExeDirectory GLOBAL setting. Give users, or users with specific roles, access to the application by setting the AccessLevel PERFANA program setting. Once a user has sufficient access rights, they can run the QC Analysis application either from the QC node on the CCLAS menu or directly from the CCLAS Exe folder.

To display tips to users upon start up of the QC Analysis application, enable the ShowTipOfTheDay PERFANA program setting, and enter the tips, with one tip per line, in a text file, place the file in a folder under the CCLAS root folder defined by the CCLASRootDirectory GLOBAL setting, then set the TipofTheDayFile PERFANA program setting to the folder and file name, for example %CCLASRootDirectory%TIPS\QCANALYSIS.TIP.

To maintain the window size and position between closing and launching the QC Analysis application, set the Window PERFANA program setting..

Configuring the Searching of Discrete QC Sample Assessments

Set the MainListViewColumnn PERFANA program settings to specify which columns of quality control sample details from the PERFANA table are presented in the discrete QC sample grid.

When entering search criteria to filter discrete historical QC observations by client, the F2 function key is used to open the client lookup form to display matching client codes from all laboratories, including clients that are disabled. Set the ClientLookupColumns PERFANA program setting to define the CLIENT table columns displayed in the client lookup form.

Customising the Searching of Discrete QC Sample Assessments

Where the PrfUDF.VBS VBScript file is located in the folder defined by the ConfigDirectory GLOBAL setting and:

  • The PrfUDF1 subroutine exists within the script file, before QC history records are extracted to analyse the performance of discrete QC samples, then it is run to customise the query.
  • The PrfUDF2 subroutine exists within the script file, after QC history records are extracted to analyse the performance of discrete QC samples, then it is run to customise the result set.
Configuring the Reporting of Discrete QC Sample Assessments

Set the TemlateDirectory PERFANA program setting to the folder containing report templates for discrete QC sample assessments report generation.

Set the DefaultViewMode PERFANA program setting to the default setting for the report generation view mode.

Customising the Reporting of Discrete QC Sample Assessments

Where the PrfUDF.VBS VBScript file is located in the folder defined by the ConfigDirectory GLOBAL setting and:

  • The PrfUDF3 subroutine exists within the script file, before discrete QC sample assessments are reported, then it is run to customise the input data to the report.
  • The PrfUDF4 subroutine exists within the script file, after discrete QC sample assessments are reported, then it is run to customise the presentation to the user.
Configuring the Plotting of Discrete QC Sample Assessments

Customising the Plotting of Discrete QC Sample Assessments

Where the PrfUDF.VBS VBScript file is located in the folder defined by the ConfigDirectory GLOBAL setting and:

  • The PrfUDF5 subroutine exists within the script file, before discrete QC sample assessments are plotted, then it is run to customise the input data to the plot.
  • The PrfUDF6 subroutine exists within the script file, after discrete QC sample assessments are plotted, then it is run to customise the presentation to the user.
Access a Custom Form from QC Performance Analysis

Often a laboratory requires custom scripts to tailor QC performance analysis to their requirements. These scripts may or may not include custom forms.

The PerfanaScreenn PERFANA program settings define the custom scripts that are launched from the Run main menu option.
