How are lab normal updates reflected in existing lab forms?

If you update lab normal values during a study's conduct period, these updates are reflected in all started lab forms, including existing ones, whether complete or not.

Automatic updates for lab normal ranges in lab forms do not impact a question's Signed or Verified status. Lab normal updates are still pushed to lab forms even if data is locked.

If you work with local labs, upon updating and saving a lab's normal ranges from the Sites & Labs tab, your updates are automatically refreshed in the existing lab forms five minutes after your last update was saved. For example, if you save an update to the lab normal ranges at 05:00 PM, the system begins processing the update at 05:05 PM, and the changes may take additional time to appear in all impacted lab forms, depending on the volume of updates. You can view an audit trail of that lab normal update on the Answer & Visit History sidebar.

Impact on reports

You can view which lab form rows had their lab normals updated throughout the study in the following reports:
  • In the Subject Data report, the Type of Change column indicates that a lab normal value was updated. The User Name column displays"system user" indicating that this update was performed automatically by the system in the lab form.
  • In the Subject Data Extract, the latest updates for lab normals are displayed in the applicable columns.
  • In the Lab Normal Range Report you can view all details related to how lab normal values were updated, which user performed the update, and when they made the update.

Impact on custom JavaScript rules

If any of the lab normal updates that are performed in your study impact any custom JavaScript rules, here's what you should know:
  • If a lab normal range is updated, any custom rules that reference the normal range values re-run based on the custom rule's logic. For example, if a data manager updates the lab normal range for a Creatinine test, and you have a calculation rule that references the Creatinine test field in a lab form, that calculation rule is re-run.
  • If the re-running of a custom rule for a lab normal range value results in an error, the target field is highlighted in the lab form and indicates that there's an error.
