Laboratory Messaging Standard

 

Laboratory Messaging Standards allow access, management and storage of patient laboratory orders and results across the continuum of care through a jurisdictional Laboratory Information System.

Laboratory Messaging Standard                                        CDFU/CAS *

BUSINESS FUNCTIONS BENEFITS
  • Human: submit orders; query order status; access results; refer and redirect lab-to-lab orders
  • Disciplines supported by the laboratory standard, but not limited to, are: clinical chemistry (e.g. glucose); hematology (eg. Hemoglobin); microbiology (e.g. urine culture); pathology (e.g. biopsy); (limited) transfusion medicine (blood group and antibody screening)
  • Non-Human: supports sharing of non-human laboratory information between clinical laboratories; includes water, food, animal suspicious substances testing and environmental swabs in point-to-point interfaces that affect population health; activate or revise an order; access results

NOTE: the following business functions of this standard have progressed from CDFU to CAS:

  • Request Query Laboratory Results/Find Laboratory test results
  • Laboratory Results Query Response/Find laboratory test results
 
ACCESS
  • Increases access to laboratory test results across the continuum of care
QUALITY
  • Reduces the need to repeat laboratory tests since all existing tests are accessible
  • Improves quality and timelines of laboratory results and interpretations since tests can be reviewed electronically
PRODUCTIVITY
  • Reduces storage, dissemination and duplication costs – tests can be stored and shared electronically
MESSAGING & TERMINOLOGY INFORMATION
  • Messaging: HL7 V3.0
  • Terminology: HL7 Terminology Code Systems, pCLOCD (LOINC), SNOMED CT, Unified Code for Units of Measure (UCUM)

* Status Definitions

Canadian Draft for Use (CDFU) - The standard has been developed but it may or may not be implemented or be in use. The standard is considered ready to be used by early adopters: however, change is probable as stakeholders begin using the standard in implementations.

Canadian Approved Standards (CAS) - The standard is in use for the purpose(s) or context(s) for which it was intended. Only those parts of the standard that have been implemented or are in use can progress for consideration as CAS. This decision point signifies that the standard has reached a level of stability and is comprehensive enough such that major changes are not expected.
