SGH
Segment Group Header
The SGH segment is only used to provide information about the instantiated message structure to indicate that a new segment group begins and subsequent segments SHOULD be interpreted accordingly. It does not contain any patient related data.
It is expected that each SGH will be accompanied by an SGT, as depicted below in the abstract message diagram: WRP: Widget Reports
