Unified Comment from CDC

  • Additional Use Case: This is a standard data item used by central cancer registries in all states. Data received through data exchange from laboratories to central cancer registries for CDC and NCI’s national cancer surveillance systems, as required by law.    
  •  CSTE supports inclusion of this measure into USCDI v3: very useful for laboratory related fields context.

APHL comment to add into USCDIV2

This data element is critical in supporting specimentype information, when more generic types are submitted - for example a joint fuild sample or a tissue sample - rather than supporting a lot of pre-coordinated (and still potentially not detailed enough specimen types) use of source site allows for a clear identification of the sample's location - critical for treating infections and cancer for example. It has been included in V2 messages for a long time (OBR-15.4) and is an RE element in ELR R1.
