HOW IT WORKS

How to read your dog or cat’s blood test results.

A lab report can feel like a lot to take in when it belongs to someone you love. Here is how we’re building a gentler way to read it, one explanation at a time.

You can explore the report and try the document selector today. This preview does not upload or analyze documents.

Step 1: bring the original lab report.

Start with the document your veterinarian or laboratory provided. Keep the test names, values, units, reference intervals, dates and laboratory comments together. A clear original document is more useful than a cropped screenshot of a flagged value.

The demo accepts one PDF, JPG or PNG of up to 10 MB. It displays a filename locally and does not read or send the document. Live formats and supported tests will be confirmed before launch.

Step 2: put the numbers in your pet’s context.

The intended service will ask about species, breed, age, sex and neuter status, weight, the reason for testing, current observations, food, medication and relevant history.

A dog’s results cannot be interpreted using human intervals, and a cat is not simply a small dog. Information that has not been provided should stay visibly unknown.

CBC and chemistry panel: common dog and cat blood work abbreviations.

Routine blood work usually combines two groups of tests. The complete blood count (CBC) counts and describes the cells in the blood. The chemistry panel measures substances dissolved in the blood that give information about how certain organs are working. A urinalysis can complete the picture.

AbbreviationWhat the measurement describes
RBC, HGB, HCTRed blood cells, the haemoglobin that carries oxygen and the share of the blood occupied by these cells.
WBC, neutrophils, lymphocytesThe cells involved in the body’s defences, counted in total and then by type.
PLT (platelets)Small blood components that form the first plug when a blood vessel is damaged.
BUN, creatinine, SDMASubstances largely removed by the kidneys, often followed in senior pets.
ALT, ALP (ALKP)Enzymes found mainly in the liver; ALP also comes from other tissues.
GLU (glucose)The amount of sugar in the blood when the sample was taken.
  • Read each value against the reference interval printed by the laboratory that measured it: it can differ by species, method and analyser.
  • A high or low flag is not a diagnosis, and a value within the interval does not guarantee that everything is fine.
  • Stress during sampling or a recent meal can change some results, which is one reason your vet gives instructions before blood work.

Step 3: read the explanation at your own pace.

Profile & summary

A profile and an overview that brings related results together.

Marker explanations

Definitions, units, laboratory intervals and contextual explanations of both flagged and in-range results.

Wellbeing & next steps

Everyday wellbeing information, practical organization and questions for your vet.

Step 4: bring your questions to your vet.

Use the report to identify what you understand and what still needs explaining. Your veterinarian combines laboratory information with the examination, history and other findings.

The AI can make mistakes and cannot examine your animal. Do not use it to select treatment, change medication or delay veterinary care.
