Clinical Use in Everyday Veterinary Practice
Quick definition
Role: functional screening and prioritisation early in the consultation
Measures: patient response to DAMNIT-V–aligned test signals (RAC-type events)
Use: guides where to investigate first
Confirmation: diagnosis always requires standard veterinary diagnostics
The DAMNIT-V Screen is used early in the veterinary consultation as a functional screening and prioritisation tool. It does not determine diagnosis or treatment. Its role is to provide early physiological context that helps clinicians decide:
Where should I look first?
In routine practice, the DAMNIT-V Screen may be run for every consultation—either prior to the appointment or while history is being taken and the physical examination is performed. Results are recorded alongside history, examination findings, pathology, and imaging, and are not used in isolation.
To understand how the DAMNIT-V Screen works and its scientific boundaries, see the About page.
A Standard Consultation Workflow
- History + Physical Examination
- DAMNIT-V Screen run concurrently
- Results reviewed as a functional overview
- Targeted diagnostics and treatment planned according to standard care
The screen did not dictate treatment.
It supported prioritisation and clinical reasoning.
Spectrum of Clinical Presentations
Rather than being limited to specific diseases, the DAMNIT-V Screen proved most useful across a spectrum of common veterinary presentations, particularly when cases were:
- vague or early
- multifactorial
- recurrent
- costly to investigate sequentially
- associated with diagnostic uncertainty
Overview of Clinical Utility
| Presentation type | Clinical question | How the DAMNIT-V Screen helped |
| Dermatology | Local vs systemic driver | Prioritised allergen, immune, or metabolic focus |
| Otitis externa | Primary vs secondary process | Identified dietary, immune, or inflammatory relevance |
| Collapse / weakness | Toxic vs non-toxic | Supported early triage and prioritisation |
| Chronic pain | Skeletal vs visceral | Guided examination and diagnostic direction |
| Complex / unclear cases | “Something isn’t right” | Reduced diagnostic scatter and uncertainty |
This pattern-based use reflects how experienced veterinarians already think — broad first, narrow carefully.
Representative Clinical Examples
The following brief examples illustrate how the DAMNIT-V Screen was used in practice.
They are illustrative, not exhaustive.
Example 1: Chronic Pruritus
Presentation:
Pruritus with alopecia of the 1/3rd hind quarter in a small dog.
Standard work-up:
Skin examination, scrapings, dermatological testing, thyroid assays.
Screen contribution:
Functional response pattern suggested allergen relevance, with bias toward contact exposure.
Clinical impact:
Environmental modification (removal of rubber-based contact materials).
Outcome:
Resolution of lesions and hair regrowth.
No escalation of diagnostics , CytopointR symptomatic medication used as a single dose.
Example 2: Thrombocytopaenia
Presentation:
Thrombocytopaenia in Cavalier King Charles Spaniel, delayed desexing. 10 months later Grade 4 dental disease, still thrombocytopaenic 100K/uL, normal PCV.
Screen contribution:
| Signal Tested | Duration | RAC Detected |
| Neu5Ac | 5.00 | 20 |
| Neu5Gc | 5.00 | 5 |
| Canine_TUBB1_p.D249N_mutant | 5.00 | 35 |
| TUBG1 | 5.00 | 15 |
Clinical impact:
Genetic basis – Caused by mutations in the TUBB1 gene, which encodes beta-1 tubulin, a protein critical for platelet formation.
Two main mutations identified: TUBB1 c.745G>A (p.D249N) in Cavalier King Charles Spaniels.
TUBB1 c.5G>A (p.R2H) in Cairn Terriers.
DAMNIT-V Screen findings suggested a pattern consistent with a hereditary thrombocytopaenia phenotype typically not associated with clinically significant bleeding. This was supported clinically by the presence of Grade 4 dental disease with normal PCV and no excessive haemorrhage.
Outcome:
Proceeded to GA and extract four teeth, minimal to no bleeding experienced. Genetic test still pending 4 months after testing.
Example 3: Acute Collapse (Australia)
Presentation:
Sudden collapse and weakness.
Differentials:
Snake envenomation, tick paralysis, spider envenomation, other toxicities.
Screen contribution:
Early identification of toxicological relevance and prioritisation of toxin category.
Clinical impact:
Faster triage and targeted supportive management while standard protocols were followed.
What These Cases Illustrate
These examples are not unusual or exotic.
They reflect:
- daily consults
- familiar presentations
- common diagnostic dilemmas
The difference was not what was treated, but how quickly diagnostic direction was clarified. As with any clinical tool, not all cases demonstrated actionable functional patterns.
What the DAMNIT-V Screen Contributed
Across routine and complex cases, the DAMNIT-V Screen functioned as:
- a prioritisation tool
- a decision-support aid
- a method to reduce diagnostic uncertainty early
It did not replace evidence-based medicine.
It made it easier to apply efficiently.
Clinical Boundaries
The DAMNIT-V Screen:
✔ supports standard veterinary workflows
✔ integrates with pathology and imaging
✔ assists within the spectrum of care
It does not:
✘ diagnose disease
✘ detect pathogens, toxins, or hormones
✘ predict future illness
Summary
The DAMNIT-V Screen was developed and refined through everyday clinical use.
Its value lies in clarity, restraint, and repeatability, supporting the way experienced veterinarians already practise:
Start broad. Narrow carefully. Investigate appropriately.
DAMNIT-V Screen is designed for clinicians who value clarity, restraint, and decision-making grounded in real practice.
