The science behind Vetica

Two focused saliva checks: inflammation and gluten.

Vetica measures two distinct salivary IgA responses. Inflammation Check looks at an immune response directed against calprotectin, a protein associated with inflammatory activity. Gluten Response looks at an immune response directed against gluten. The two tests answer different biological questions and are designed to be interpreted with symptoms, diet and history.

See where the marker science comes from, how it moved into veterinary research, what Vetica measures in dog saliva, and how to interpret a result in context.

Scientific lineage

Established biology. Veterinary research. A canine saliva format.

Vetica’s marker selection is grounded in established biomarker science. Calprotectin is an established inflammation biomarker in human gastroenterology, while antibody testing is central to the evaluation of gluten-related disease in people. Veterinary researchers have since studied calprotectin and gluten-related antibodies in dogs. Vetica’s tests build on that background while measuring different, defined salivary IgA responses in dogs.

  1. 1

    Human inflammation biomarker science[1]

    Fecal calprotectin is used in human inflammatory-bowel-disease care as a biomarker of intestinal inflammation.

  2. 2

    Human gluten serology[2]

    Antibody serology is part of the evaluation of celiac disease and other gluten-related immune responses in people.

  3. 3

    Canine biomarker research[3, 4, 5]

    Researchers have measured calprotectin in dog saliva and studied gluten-related antibody responses in dogs.

  4. 4

    Vetica canine saliva tests

    Vetica measures salivary anti-calprotectin IgA and anti-gluten IgA using rapid lateral-flow tests designed for dogs.

Human and canine research provide the biological background. Vetica applies that foundation through distinct canine salivary IgA tests, with Vetica-specific canine work evaluating the test format.

Why these are two different questions

Food can be part of the picture alongside other possible contributors. Inflammation Check asks whether the body is showing an inflammation-related immune response. Gluten Response asks whether one defined dietary exposure — gluten — is showing a response worth investigating.

Gluten was selected as a focused dietary question because it is a defined exposure that can be investigated across the whole diet — food, treats, chews, supplements, and extras. Gluten-containing ingredients may also be used for structure, binding, or texture in treats and other products, making exposure less obvious when only the main food is considered. This offers a focused starting point rather than a long list of possible ingredients.

Inflammation Check

Looks beyond individual food ingredients.

Gluten Response

Checks one practical dietary exposure early, before a longer ingredient search.

2-Test Kit

Combines both checks into one starting picture.

How can saliva tell us something about the gut?

Your dog’s body has a built-in warning and response system. When something is irritating or stressing the digestive system, the body can respond in ways that leave measurable signals. Vetica looks for two of those responses in saliva: one related to inflammation and one related to gluten.

The mouth and gastrointestinal tract are part of the body’s connected mucosal immune system. Immune responses generated at mucosal surfaces can be reflected in saliva, which makes saliva a practical place to look for selected antibody responses without blood collection.

Inflammation Check

Is the body showing an inflammation response?

Gluten Response

Gluten is a practical first dietary question because exposure can extend beyond the main food.

Together, the two tests help you look at both a broader biological response and one focused dietary question.

Vetica-specific evidence

Vetica evaluated the two saliva tests in dogs.

A prospective observational field study evaluated the Vetica saliva tests in client-owned dogs with different clinical presentations.

Observed results from Vetica’s prospective observational canine field study.

The study was designed to evaluate how the two Vetica saliva markers behaved across clinical groups. As a prospective observational study, it provides cohort-level evidence that informs continued evaluation of the canine test format.

Three kinds of evidence answer three different questions

Biological background

Why calprotectin, gluten-directed antibodies and mucosal immunity are biologically relevant areas to study.

Vetica-specific evidence

How the Vetica saliva tests were evaluated in client-owned dogs in the Vetica field study.

Veterinary practice guidance

How symptoms, diet history, controlled food trials and appropriate veterinary evaluation are used to determine clinical relevance.

Each evidence layer answers a different question: external research establishes the biological rationale, Vetica-specific work evaluates the canine assay format, and veterinary guidance informs how results can be used alongside symptoms, diet history, and appropriate evaluation.

Supporting research

Human calprotectin [1]

What the research shows

Human gastroenterology uses fecal calprotectin as a biomarker of intestinal inflammation, including alongside symptoms and endoscopic assessment in Crohn’s disease.

Why it is relevant background

This establishes the long-standing biological relevance of calprotectin as an inflammation marker. Vetica applies this biology through a different measurement: salivary anti-calprotectin IgA in dogs.

Human gluten serology [2]

What the research shows

Celiac-disease evaluation uses antibody serology as part of the diagnostic pathway in people.

Why it is relevant background

This provides a biological precedent for measuring gluten-related immune responses. Vetica applies that concept through a distinct canine salivary anti-gluten IgA test.

Canine salivary calprotectin protein [3]

What the research shows

A 2025 study found that canine salivary calprotectin protein can be measured and observed higher values in selected systemic inflammatory and immune conditions.

Why it is relevant background

This supports the biological relevance of calprotectin and saliva in dogs. Vetica-specific canine work separately evaluates the salivary anti-calprotectin IgA format.

Canine gluten and gliadin antibodies [4, 5]

What the research shows

Canine studies support gluten- and gliadin-directed antibody responses as biologically plausible in selected populations. Other serological work also shows that food-related antibody panels can have limited specificity for chronic enteropathy.

Why it is relevant background

This supports the rationale for studying a defined gluten-directed response in dogs. Vetica-specific canine evidence evaluates the salivary format, with results interpreted alongside exposure, symptoms, and history.

Controlled diet trials [6, 7, 8]

What the research shows

Veterinary guidance uses controlled elimination diets followed by reintroduction or challenge, when appropriate, to determine whether food is clinically relevant.

Why it is relevant background

A biological result and a food trial answer different questions. The result can inform what deserves attention; the controlled change shows what happens to the dog’s symptoms.

A test result and a food trial answer different questions.

Vetica provides a focused biological result. A controlled food trial shows what happens when exposure changes. Used together, they add different kinds of information to the same decision.

Vetica can be used earlier than many other approaches — before a food trial, a broader ingredient search, or a routine veterinary evaluation when appropriate. A result can also remain useful alongside veterinary findings, diet history, and symptoms, and Vetica can be used again later when another point-in-time measurement would help.

A follow-up Vetica test is optional. It adds another point-in-time result that can be interpreted alongside symptoms, diet changes, and the overall pattern.

How veterinarians investigate food-related problems

Vetica is designed to complement established veterinary workflows.

What your result gives you — and what completes the picture

What the result gives you

  • • A qualitative result from that saliva sample.
  • • A focused biological clue to use with symptoms and history.
  • • A result that can be saved and shared in the Vetica app.

What completes the picture

  • • Possible causes are interpreted with symptoms, diet, history, and veterinary findings.
  • • Severity and urgency come from your dog’s condition and symptoms, not line darkness.
  • • Food allergy is evaluated through appropriate veterinary workup and controlled diet trials when relevant.
  • • If symptoms continue after a negative result, other explanations remain worth considering.
  • • Line darkness is not used as a quantitative measure.

If your dog is worsening or has concerning symptoms, veterinary care should not wait for a test result or a food trial.
