Standardising pathology data

We are adopting a universal standard to improve the way health information and data is exchanged among clinicians and care teams. The standard is an agreed national framework known as Pathology Information, Terminology and Units Standardisation (PITUS). This initiative is backed by the Australian Government, and is in accordance with recommended guidelines and best practice.

The first release was published in September 2023 and changes will continue to be made in phases. There will be small adjustments to test names and electronic reports, and there may be minor visual changes on cumulative patient histories, depending on your practice management software.
