Structures

This structure refers to these other structures:

• ServiceRequest - Lab Orders (http://moh.bw.org/StructureDefinition/lab-order-service-request)
• Botswana Patient (http://moh.bw.org/StructureDefinition/bw-patient)
• Practitioner (http://moh.bw.org/StructureDefinition/practitioner)
• Organization (http://moh.bw.org/StructureDefinition/service-organization)
• DiagnosticReport - Lab Order (http://moh.bw.org/StructureDefinition/lab-order-diagnostic-report)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Task.identifier
• The element 1 is sliced based on the value of Task.output.value[x]
