Delete custom lab grading script

Lab grading is the categorization of lab results into predefined levels to simplify the interpretation of laboratory data. It consolidates the landscape of numerical values into actionable insights that can guide study decision-making and research analyses. Grading the severity of abnormal lab values is typically guided by the protocol or other scientific criteria relevant to the study. Biostatisticians develop an R script to implement the grading scheme where they define criteria for abnormality levels based on the range of collected lab values as recorded in different CRFs.

A default R script is built into the EDC system for grading lab results. When you upload a custom script, it takes precedence and becomes the active grading mechanism during the raw data package generation. While you are free to upload an unlimited number of custom scripts, you can also delete any that are outdated or represent older versions.

Important

You can only delete custom lab grading scripts since the default one is hardwired into the system by EDETEK biostatisticians to comply with industry standards for lab data grading.

To delete a custom lab grading script

  1. In the EDC application header, select the STUDY INFO tab.

  2. In the left pane of the page that opens, select Conversion > Conversion Define.
