Activate/Inactivate 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. However, there may be instances where you need to inactivate this custom script in order to activate a different one for lab data grading.
Important
While multiple lab grading script files may exist, only one can be active at any given time. The system relies on a single active script for specific instructions when grading lab data during raw data package generation.

Important
If all existing lab grading scripts are inactivated, the system does not perform the grading of lab data during raw data package generation.
Once selected, the lab grading script is activated or inactivated.
