Diagnostics and laboratory tests

Pre-surgical/pre-anaesthetic blood test prices at UK vets

A blood test before an anaesthetic or surgery.

Published prices

No practice on our list publishes this price yet: vet businesses with 15 or more practices or out-of-hours centres must publish it, if they offer it, on each practice's website from 23 December 2026, and smaller practices from 23 March 2027.

What it is

The CMA's definition is a "Chem10 blood test, or equivalent" (Explanatory Note, Annex 1).

Official price-list name: Pre-surgical/pre-anaesthetic blood test (CMA Order, Schedule 1).

What's included

  • Anything that is an essential part of the service, and VAT (Art. 7(2)(d) and (f))

Diagnostics and laboratory tests

Schedule 1 groups nine items as diagnostics and laboratory tests, and says all of them include interpretation: the price should cover a vet reading and explaining the result, not only taking the sample or the image.

Why the price varies

  • Whether it is already in a procedure's price. If a spay or castration price leaves blood tests unticked, add this price to compare it fairly with a practice that includes them.
  • Outside providers. If part of the work is done by someone else, such as an outside laboratory or a visiting specialist, the listed price must include their fees (Art. 7(2)(k)).

Background

It matters for comparing surgery prices. For a dental assessment, castration and both spays, the price list must tick whether pre-operative blood tests are included in the procedure's price (Art. 7(2)(e)).

Questions to ask the practice

  • Is the blood test included in the procedure's price, or extra?
  • Is it done in the practice or sent to a laboratory?

We explain prices, not treatment. Ask your vet about the clinical choices for your own pet.

The rules

What the practice's price list must show, with the Order's article references

The exact name from Schedule 1, “Pre-surgical/pre-anaesthetic blood test”, with no free-text description (Art. 7(2)(a)).

As for every item: each version on its own line with the standard one marked, a cat price and five dog bands where the price depends on the animal, and VAT included, kept up to date and changed before a higher price is charged (Art. 7(2)(b), (c), (f) and (g), and 7(5)).

A price that includes interpretation of the result (Schedule 1).

Any third-party fees for parts of the work done by someone else (Art. 7(2)(k)).

Large vet groups must publish from 23 December 2026 and smaller practices from 23 March 2027 (Art. 3 and 7).

Questions

Does my pet need a blood test before surgery?

That is a clinical decision for your vet. The price list only shows whether it is included in the procedure's price and what it costs on its own.

Why might my bill be higher than the listed price?

Listed prices are for the typical case. Each price list must say so, and must warn that prices may go up in more complex or complicated cases (Art. 7(2)(l)). The price must still include anything that is an essential part of the service (Art. 7(2)(d)).

How up to date are the prices here?

Every price shows the date we last checked it and links to the practice's own page. We re-check weekly, and daily from 23 to 31 December 2026. If a price looks wrong, email [email protected].
