Dog and Cat Blood Test Results: What the Panel Is Looking For
The printout comes back as a column of abbreviations and a column of numbers, and somewhere on it there is usually a flag. It is a natural first move to photograph the sheet and search the abbreviations one at a time, and it is also the wrong order — because dog blood test results, and cat ones, are not a set of independent verdicts. They are one picture, and the picture only resolves when it is held next to the animal it came from.
This page explains what each part of the panel is asking about. It deliberately does not publish reference ranges or tell you what a particular figure means, because a number read without the examination that goes with it is anxiety with a decimal point. What follows is the reasoning, which is the part you can genuinely use.
A panel is a screen, not a verdict
Blood work is a wide net thrown cheaply. In one small sample we can ask questions of the kidneys, the liver, the sugar handling, the salt balance and the cells themselves, all at once, without knowing in advance which of them is the problem.
That breadth comes at a price, and the price is precision. A screen is deliberately built to be sensitive — it would rather flag something that turns out to be nothing than stay silent on something that turns out to matter. So a flag is not a diagnosis. It is the panel saying look here next, and the looking is done with the examination, the history, sometimes a urine sample, and often a repeat test a few weeks later.
The chemistry half asks how the organs are coping
Roughly half the sheet is biochemistry, and each cluster on it is a proxy for an organ doing its job.
The kidney markers are waste products that healthy kidneys clear from the blood continuously. When clearance falls, those products accumulate, which is why they rise. Two things are worth knowing about them. They are late signals — a considerable amount of kidney capacity can be lost before they move at all. And the blood answers only part of the kidney question, which is why we ask for urine in the same visit: what the kidneys are doing with water is a separate measurement from what is left circulating. If collecting a sample at home sounds impossible, say so when you book, because collecting one here during the appointment is usually straightforward and it saves you a second trip.
The liver group is really two groups wearing one label. Some values are enzymes that leak out when liver cells are irritated or damaged, so they report on injury to the cells. Others report on function — whether the liver is still making and clearing what it is supposed to. Those two can move independently, and a liver can be irritated while still doing its work, which is why an enzyme flag on its own is not read as liver failure.
Glucose asks about sugar handling. It is central to diabetes, but it is also the value most easily disturbed by the visit itself, particularly in cats — a stressed cat can raise his own blood sugar on the table, which is why a single high reading in a frightened patient is not acted on alone.
Then there are proteins and electrolytes, which are quieter than the headline values and more useful than they look. They speak to hydration, to salt balance, to whether protein is being lost somewhere it should not be. In a hot climate they carry more weight than they would elsewhere, because a dog who has been panting in a car park for twenty minutes is not in the same state as one who walked in from an air-conditioned lobby.
The count half asks about the cells themselves
The other half is the complete blood count. It looks at the cells themselves — how many there are of each kind, and in what proportion.
Red cells carry oxygen, so the count and the proportion of blood they occupy tell us whether the body is short of them. Low can mean loss, destruction, or simply that not enough are being made, and those three lead in very different directions, so this is a value that opens an investigation.
White cells are the response system. What matters here is the direction and the mix more than the headline figure, because different types rise in different circumstances — infection, inflammation, stress, and the effect of certain medicines all leave different signatures. A white cell count describes a response; it does not name the cause.
Platelets are the clotting cells, and in this region they earn particular attention. Tick-borne disease is part of the local picture for dogs here, which is one reason a dog who is simply flat and off his food gets a count run early. What that illness does and how it is tested is on our tick fever page.
One value outside the range is rarely the story
Reference ranges are built from populations, which means a proportion of entirely healthy animals sit outside them by definition. Breed shifts them. Age shifts them. A long car journey, a missed meal, a fight in the carrier — all of these shift them.
So we read the pattern across the whole sheet, and a single point in isolation carries very little on its own. Several values moving together in a way that makes biological sense is a finding. A single mild flag in an animal who looks well and examines normally is a different object, and whether it calls for a repeat in a few weeks or for something more is a decision your vet makes with the examination in front of them.
The pattern that matters most is the one across time. A value that has drifted steadily across three annual panels is far more informative than the same value seen once, and this is the strongest practical argument for running blood work while your pet is well. Without a baseline, the first panel we ever run on a ten-year-old cat gives us a photograph when what we needed was a film.
The numbers only mean something next to the animal
The same sheet can be reassuring in one patient and urgent in another. A mildly raised marker in a bright three-year-old who is eating normally, holding his weight and examining clean is a different object from the identical figure in a fourteen-year-old who has lost weight since the last visit and started drinking more.
That is why we do not read results down the phone as a list. We read them against what we found in the room — the weight trend, the hydration, the mouth, the abdomen, what you told us about appetite, thirst and energy at home. Those observations are part of the annual check-up itself.
It also means the most useful thing you can bring is an honest account of what has changed at home, and when. Bring the printout from a previous clinic as well, but the account is what shapes how we read it.
Having the lab in the building changes what you can decide today
When a sample is couriered out to an external laboratory, the answer comes back days later. For a routine screen that is fine. For a pet who is unwell today, it is the difference between treating and guessing.
We run blood chemistry, complete blood counts and urinalysis inside the clinic at Al Quoz 3, which means the sample does not travel and the results are read back to you before you leave — the detail is on the page for our in-house laboratory. In practice that decides three things on the spot: whether fluids start today or he goes home, whether a planned anaesthetic proceeds in the morning, and whether a drug is safe for this particular liver or needs swapping for another.
In a city where crossing town at the wrong time of day is not a quick trip, that compression matters more than it sounds. A worried owner who would otherwise go home to wait for a phone call leaves with an answer and a plan, and treatment that a courier timetable would have pushed to Thursday starts the same day.
What it costs
At Petbook the consultation that has to come first is AED 120, and that is a published price. The panel itself varies, because what we run depends on the question — a pre-anaesthetic screen, a senior wellness profile and a full work-up on a sick patient are different tests at different prices, and quoting one number for all three would be misleading.
