Such analysers, however, are invaluable in some clinical settings. The appearance on the market of small, light, inexpensive, multi-purpose, point-of-care analysers, which combine a number of widely differing analytes, has to some degree upset this paradigm. 16-21.Point-of-care testing (PoCT) is traditionally considered a branch or offshoot of clinical chemistry.

We have published quite a few papers about our work in the NT POCT Program. We are funded by the Northern Territory Government - NT Health. The WBC DIFF device generates a total white cell count and a 5-part differential white blood cell count in under 5 minutes.īased on our research the WBC DIFF POCT program is expected to have significant benefits for Top End communities, including rapid identification and timely treatment of patients with infection/sepsis, more effective triage of patients who require evacuation (by making informed clinical decisions on-site as a result of access to POC testing), and cost savings due to prevented medical evacuations.
In 2020, this study led to the introduction of HemoCue (R) WBC DIFF devices to 20 remote clinics in the Northern Territory's Top End region. In response to this, NT Health and the Flinders University International Centre for Point-of-Care Testing examined the analytical, clinical and cost effectiveness of a point-of-care testing device for total white cell counts and their subtypes.
Our 2017 study found that more than 25% of tests ordered by remote communities were reported by their nearest laboratory as 'unreliable', 'unsuitable' and 'not reported' due to these issues. These challenges include long specimen transport times and issues related to specimen integrity during transport. White cell counts are an important diagnostic tool for detecting acute and general infections, but obtaining reliable test results in a timely manner from pathology laboratories presents significant challenges for remote communities.
