Senior pet blood screening cost in the UK: what a wellness screen is worth
As dogs and cats reach their senior years, many vets offer a wellness blood screen to catch problems like kidney or thyroid disease before your pet looks obviously ill. These screens run a panel of blood tests, sometimes with a urine sample, to build a health baseline. The real prices below show the range, and this guide helps you judge the value.
The quick version
- Senior screens use blood tests to check organ function, blood cells, and often thyroid, aiming to catch disease early.
- A baseline while your pet is well makes future results far easier to interpret when something changes.
- Prices vary with the size of the panel, whether urine is included, and whether it is bundled into a senior health check.
- Early detection can head off larger bills later, since managing a condition early is usually cheaper than treating a crisis.
What people actually paid
The gap: advertised vs actually paid (medians)
People reported paying 381% more than the advertised list price for blood tests.
List prices are advertised prices; paid figures are what people reported, often for different cases and from a small sample so far. Treat the gap as a signal, not a quote.
Real prices, in people's own words
- £400“it was nearly £400 for bloods, injection, and two not very expensive meds”
- £457“blood tests, antibiotics and a pain relief injection cost me £457!!!”

Why the price varies so much
The main driver is how much is tested. A basic panel checking kidney and liver values costs less than a full screen that adds a complete blood count, thyroid, and a urine test. Many practices bundle the bloods with a nurse or vet consultation and blood pressure check, which changes the headline figure. Cats and dogs sometimes have slightly different recommended panels. Where the sample is analysed matters too, with in-house machines and external laboratories priced differently. As with all vet care, corporate-owned practices sit around 18.3% above independents on average, per the CMA's 2026 findings, and overall vet prices rose roughly 63% between 2016 and 2023.
How to pay less
- Ask exactly which tests are in the panel and whether a smaller, targeted screen suits a pet with no symptoms.
- Look out for senior wellness packages or health plan memberships that bundle screening at a lower combined price.
- Book screening alongside an appointment you were already having, such as annual vaccinations, to save a separate consult fee.
- If you have pet insurance, check whether wellness screening is covered, as routine tests are often excluded and worth budgeting for.
Common questions
At what age should I start senior blood screening?
It depends on species and breed, but many vets suggest starting around seven for dogs and cats, and earlier for giant breeds that age faster. The idea is to get a baseline while your pet is healthy. Ask your vet what fits your individual animal, as a large-breed dog and a small terrier will not be on the same timeline.
Is a senior wellness screen actually worth paying for?
For many older pets it is, because conditions like kidney disease and an overactive thyroid develop quietly and are far easier to manage when caught early. It is not compulsory, though. If cost is tight, ask your vet to prioritise the most useful tests for your pet's age and breed rather than the full panel.
What happens if the screen finds a problem?
An abnormal result usually leads to a conversation about next steps, which might be a repeat test, a urine sample, imaging, or starting treatment. Catching something early often means simpler, cheaper management. Your vet should explain what each finding means and let you decide how far to investigate rather than rushing into extra tests.
