ANSI/HL7 V3 LBRESULT, R1-2009: HL7 Version 3 Standard: Laboratory; Result, Release 1

Summary

The laboratory domain comprises the models, messages, and other artifacts that are needed to support messaging related to laboratory tests or observations. It currently supports the results of laboratory testing of any type of specimen, including human, animal, and environmental specimens. In future it is additionally intended to support ordering of laboratory tests, and may include templates for microbiology reporting and other specialized laboratory domains.

Description

The HL7 Laboratory domain includes the provision and use of analytic services in areas such as chemistry, hematology, serology, histology, cytology, anatomic pathology, microbiology, and virology. Blood bank and transfusion services are covered in the Blood Bank domain. [Note that not all lab specializations will be supported in the first HL7 V3 release.]

Analytic services typically result in observations returned to the order placer and/or added to the patient medical history. Observations may be simple numeric quantitative measurements, such as a blood serum glucose level, or complex diagnostic pathology reports.

Services may be delivered/executed at an external lab, an on-site lab, or at the point of care. This section covers service requests from all locations, including bedside and in-hospital, clinic and outpatient, and lab-to-lab interactions. It includes orders accompanied by specimens to be analyzed, as well as orders for which the service provider is responsible for obtaining the specimens. Observations (results) may be generated for both ordered and unordered (e.g., POC) tests.
