FHIR Message

The FHIR equivalent is the Laboratory Order (O21) message: a Bundle Message whose MessageHeader has eventCoding v2-0003 O21 and focus the Laboratory Order(s). ORL^O22 is a FHIR response message (MessageHeader.response). Order control (ORC-1) maps to ServiceRequest.status - see v2-0119-to-request-status.

Example

A GP requests a full blood count.
