More Than a Test Result: What’s Changing in Veterinary Diagnostics in 2026?

Earlier disease detection and increasingly accessible diagnostic tools are opening new possibilities, while also raising practical questions around when to test and how findings should influence patient care.

Across the London Vet Show 2026 programme, experts are exploring these themes from a range of clinical perspectives. Below are some of the key areas of focus, along with the sessions taking a closer look at them.

Clinical Pathology: More Than an Automated Result

Automation is playing an increasingly important role in veterinary clinical pathology, with in-house analysers able to generate detailed haematology information quickly. But technology hasn’t made hands-on techniques any less valuable. Familiar skills can still provide important context when a result needs a closer look.

Blood smear examination is one example. Kate Irvine, Pathology Manager UK at Antech Diagnostics, will explore the practical side of the technique in Smear Tactics: Making and Reading Blood Smears. Antech Academy will also explore blood gas interpretation in Acid, Base and Everything in Between: Getting to Grips with Blood Gases, extending the focus to another area of diagnostic decision-making.

It’s a good example of how veterinary diagnostics can bring new technology and established techniques together, rather than having one simply replace the other.

A Clearer Picture: Veterinary Diagnostic Imaging in 2026

Not every development in veterinary diagnostics comes from a new test. Familiar tools such as radiography remain central to diagnostic imaging, while focused approaches such as POCUS offer another way to investigate what is happening with a patient.

Thoracic radiography is one area in focus at London Vet Show 2026. Veterinary radiologist Cathy Beck will present Peeking Through the Shadows: How to Make Sense of Thoracic Radiographs, bringing a structured approach to an area that can take time to master.

Cathy Beck will also join emergency and critical care lecturer, Laura Cole, for Be Aware and Take Care: Practicalities and Pitfalls of POCUS. Together, the sessions explore two sides of veterinary diagnostic imaging: building confidence with an established technique while considering how focused imaging can fit into the wider diagnostic picture.

Finding Disease Earlier: What Comes Next?

Finding disease earlier sounds like an obvious advantage. But as diagnostic options develop, a more complex question is emerging: does earlier detection meaningfully change how we manage a condition?

That question is particularly relevant in chronic conditions such as feline kidney disease, where earlier identification may create more opportunities for monitoring and intervention. It’s a question explored directly in In Purr-suit of Health: Does Early Detection and Intervention Help in Feline CKD?, which examines the relationship between earlier detection and what comes next for the patient.

Cancer diagnostics add another dimension to the conversation. What Is IDEXX Cancer Dx and When and How Should I Use It in Practice? reflects growing interest in where newer diagnostic approaches could fit into clinical decision-making.

The bigger question for veterinary diagnostics isn’t simply, “Can we detect it earlier?” It’s, “What can we do differently once we know?”

When a Test Result Doesn’t Mean Treatment

A positive test result doesn’t always mean treatment is the next step. Diagnostics can also help build the case for holding back, particularly when it comes to responsible antimicrobial use.

Culture and sensitivity testing is part of that picture, helping identify the organisms involved and their susceptibility to different antimicrobials. Making Sense of Sensitivity: How to Best Use C&S Results to Guide Responsible Antimicrobial Use brings the relationship between testing and treatment into focus.

The same thinking runs through Urinary Tract Infections: Brave Decisions and When Not to Treat, delivered by Protexin Veterinary, shifting the conversation from simply identifying an infection to considering when intervention is actually appropriate.

Together, these sessions reflect a broader role for diagnostics: not just identifying what might be wrong but providing evidence that can support more considered treatment decisions.

Making Complex Cases Easier to Navigate

Not every case follows a straightforward diagnostic path. Some bring together different findings, tests and clinical considerations, putting the focus on how complex investigations are approached and pieced together.

Morgane Canonne, lecturer and researcher at Alfort French National Veterinary School, will explore one such investigation in Thirst Things First: Investigating Canine PUPD Cases.

Elsewhere in the programme, Clinical Approach to Chronic GI Disease in the Feline offers another perspective on navigating a complex diagnostic investigation.

Together, the sessions highlight the different ways complex diagnostic questions are being explored across the programme — from working through individual clinical signs to bringing multiple findings together.

From Diagnostics to the Bigger Clinical Picture

Reaching a diagnosis is an important part of the clinical picture, but it isn’t always the end of the story. Diagnostic findings can shape the questions that come next, from further investigation to decisions about how a condition is managed.

Don’t Stress! Simplifying Diagnosis and Management of Adrenal Tumours reflects that link between reaching a diagnosis and deciding what happens next. It’s another reminder that developments in veterinary diagnostics aren’t only about new technology; they’re also about bringing different pieces of clinical information together to support clinical decision-making.
