ORU^R01
ORU/ACK - Unsolicited transmission of an observation message
Observation Reporting
The OUL message is designed to accommodate the laboratory processes of laboratory automation systems. The ORU message is still fully supported by HL7 for transmitting laboratory results to other systems.
With the type (OBX) defined in this chapter, and the OBR defined in Chapter 4, one can construct almost any clinical report as a three-level hierarchy, with the PID segment defined in Chapter 3 at the upper level, an order record (OBR) at the next level and one or more observation records (OBX) at the bottom.
