Resultable Concept Dictionary
The Resultable Concept Dictionary (RCD) is an Allscripts list of common resultables returned on lab results. This would be a list of items such as White Blood Count (WBC), Hemoglobin, or Platelets. Mapping Resultables to the RCD currently provides no benefit. This is a feature that will be used in the future.
It is possible to have Resultable Items flow together on flowsheets without Syncing: See Flowing Resultable Items Without RCD Mapping
For more information regarding the sychronization process see V11 Order and Result Dictionary Build and Synchronization.
