logo of pCLOCD

The pan-Canadian LOINC Observation Code Database (pCLOCD) is a Canadian adaptation of the global Logical Observation Identifiers Names and Codes (LOINC) standard, tailored to meet the specific needs of the healthcare system in Canada. This standard is released on March 31 and September 30 of each year.

It provides:

Example names for laboratory viewers – Ensuring clarity in test reporting.
Recommended units of measure – Standardized for use in Canada to promote consistency in laboratory and clinical data exchange.

By aligning with LOINC, pCLOCD supports interoperability, data quality, and seamless sharing of laboratory and clinical observations across Canadian healthcare systems.
