Laboratory Performers SHALL be recorded as performers in the CDA Header as well as in the structured body as demonstrated in the figure below. Documentation of laboratory performers MAY be done in multiple levels of the document to reflect performance scope. In the case where there is a single Laboratory Performer, this entity SHALL be documented in CDA header as shown. In the case where multiple Laboratory Performers participated in the lab testing process, they SHALL be documented in the structuredBody at the observation level.
These performers SHALL conform to the General Constraints found in HL7 CRS: 2.1.1 with respect to the requirements for name, address, telephone numbers and other contact information.
This module is out of the XDS-Lab Specification and documented there in a <performer> element. This module does not change requirements stated in that specification but is structured as a module to ensure consistent content representation and re-usability.
The figure below shows how the information for this element is coded, and further constraints are provided in the following sections.
