For many decades now, diagnostic testing has followed the same path. A sample gets collected, sent to a centralised lab. Then the results come though some hours or even days later and a decision is made.

Recently, this system is being dismantled as technology evolves tools are bringing about change to testing capacity and capabilities to directly benefit the patient.

And this change is impacting how quickly clinicians can act how care is delivered especially in remote or resource limited environments and what patients experience at the point of contact

Let’s take a look.

Portable Analysers

Compact desktop and handheld analysers now run the kind of immunoassay panels that previously required a full laboratory set up.

Thyroid functions, cardiac markers, inflammatory markers and infectious disease screenings for exmaple can be run from a device that sits in a consultation room bench and returns results in minutes.

The ichroma 3 is one example of this category. It’s a point of care fluorescence immunoassay analyser that is designed to deliver lab comparable results without the infrastructure turnaround time or sample transport that centralized testing requires. This equipment is a lifesaver for those times when you need results fast but are working out of hours in a rural setting or lav access is slow.

Rapid Immunoassay Testing

Lateral flow and fluorescence based rapid tests have expanded beyond the COVID-19  applications that brought them into the public’s consciousness. Influenza, RSV, strep A, troponin, CRP, HbA1c and a growing range of other markers can now be tested rapidly at that point of care with accuracy that meets clinical decision making thresholds.

The benefit of this is that clinicians can rule in or out a diagnosis and start treatment or safely discharge a patient without waiting for external lab confirmation.

Handheld Ultrasound Devices

Pocket sized ultrasound devices are less of a novelty these days and are a clinical standard in many settings. Especially emergency medicine, critical care and primary care environments where rapid assessment is needed for things like cardiac function, fluid status, deep vein thrombosis and abdominal pathology at the bedside.

Devices like the Butterfly iQ and Philips Lumify connect to a smartphone or tablet, removing the need for a dedicated ultrasound suite and specialist technician for every scan.

Digital Pathology Tools

Whole slide imaging and AI-assisted analysis are beginning to shift aspects of pathology review away from centralised labs toward remote and distributed models. A slide digitised at a regional hospital can be received by a specialist pathologist anywhere. This reduces the turnaround time and improves access to subspecialty expertise in areas where it isn’t physically available.

Furthermore, this technology is more advanced in some cancer screening programmes than others, but the direction of travel is consistent across the field.

Remote Patient Monitoring

Wearable and home-based monitoring devices are extending diagnostic capability beyond the clinical setting entirely. Continuous glucose monitors, cardiac event recorders, blood pressure monitors with clinical-grade accuracy, and pulse oximeters feed data into managed care platforms that generate diagnostic data between appointments rather than only at the appointment itself. This means that the right data is integrated meaningfully into the pathway without creating alert fatigue or overwhelming already stretched clinical teams.
