What's included

What ongoing maintenance covers

  • Central and local lab range updates monitored throughout conduct, not just captured once at start-up
  • Each incoming range update verified against source documentation before it's applied in the database
  • Updates applied with an effective date, so historical out-of-range flags stay accurate against the range in force at the time
  • Downstream edit check logic re-checked whenever a range change could affect flagging behavior
  • Full change history retained, giving auditors a clear record of what range applied when

Updated as labs change, not just once

Range updates from labs are applied promptly, rather than leaving stale reference values in place for the study's duration.

Keeps edit checks accurate

Directly supports the range logic built during edit checks programming, so flags stay meaningful as ranges shift.
