Vet X-ray and diagnostic costs explained

Diagnostic tests are often recommended after a consultation when your vet needs more information to assess your pet's condition. They are also commonly used in emergency and out-of-hours care, where rapid imaging or blood work may be needed quickly.

The CMA includes scans and diagnostic tests in its recommended standard price-list categories for veterinary practices, which should make it easier to find published fees over time.

This guide explains the difference between imaging and laboratory tests, what affects the price, and what to ask before you agree to diagnostics.

Source note: This guide is based on the CMA's veterinary market investigation final decision report and supporting materials. It does not provide veterinary or medical advice. Which tests your pet needs is a clinical decision for your vet.

Types of diagnostic cost

Not all diagnostic costs are the same. Understanding the categories helps you compare like with like.

Imaging (scans) — visual assessments of your pet's internal structures:

• X-rays (radiographs) — commonly used for bones, joints, chest and abdomen; may require multiple views
• Ultrasound — used for soft tissues and organs; performed in real time by a trained operator

Some practices offer both in-house; others refer certain imaging to specialist centres. Advanced imaging such as MRI or CT scans is typically done at referral hospitals — ask your vet if this applies and how costs are handled.

Laboratory tests — analysis of blood, urine or other samples:

• Blood tests — from a basic panel to more extensive profiles, priced according to what is included
• Urinalysis — urine testing, sometimes performed in-house
• Samples sent externally — some tests are processed by outside laboratories, which may affect turnaround time and cost

Combined pathways — a single visit may involve a consultation plus several tests. The total cost is the sum of each component, not a single headline fee.

What is not included in the consultation fee

The consultation fee and diagnostic test fees are usually separate charges. A consultation covers the vet's examination and initial assessment — not the tests they recommend as a result.

Always ask before agreeing to tests, especially if multiple diagnostics are suggested at the same visit.

What affects the price

Diagnostic costs vary because:

• Test type — an X-ray, an ultrasound and a blood panel are all priced differently
• Number of views or images — X-rays may be charged per view or as a set; more images mean higher cost
• Sedation or anaesthetic — some pets need sedation for imaging, which adds to the total
• In-house vs external laboratory — tests processed on-site may be priced differently from those sent away
• Consultation billed separately — the consult fee is almost always additional to test fees
• Emergency or out-of-hours context — diagnostics during emergency care may be priced within a wider emergency bill
• Species and size — some practices differentiate fees by animal size, particularly for anaesthetic or imaging time

The CMA's standardised price-list remedy (Final decision report — Part B) includes scans and diagnostic tests among the categories practices will be required to publish. Remedies are being phased in over time; for the current position, see the GOV.UK landing page in Sources above.

Typical costs — what to expect

Diagnostic fees vary widely between practices, and we do not publish a UK average here because practices set their own fees, tests are often itemised separately, and our snapshot is incomplete.

Do not rely on a figure from a friend, social media or an old price list. Always ask the practice for its current fees and an itemised estimate before agreeing to tests.

Where practices have shared price data, scan and diagnostic fees may appear on WisePet practice listings. Data availability varies — diagnostics are published by fewer practices than consultations or vaccinations.

For treatment pathways expected to exceed £500 including VAT, the CMA's remedies include requirements around written estimates. See Vet written estimates and itemised bills explained.

What to ask your vet

Before agreeing to diagnostic tests, you can reasonably ask:

• Which tests are you recommending, and why?
• What is the cost of each test, and is the consultation fee separate?
• Are multiple X-ray views included, or charged per view?
• Will any samples be sent to an external laboratory?
• Is sedation or anaesthetic needed, and what does that cost?
• Can I have a written estimate before the tests proceed?
• Can I receive an itemised bill afterwards?

For more questions to use before treatment, see Questions to ask before agreeing to vet treatment.

Comparing diagnostic prices

Scans and diagnostic tests are listed in the CMA's recommended price categories. Where practices have published fees, you can compare available prices on WisePet and browse city pages where we hold enough practice data.

However, diagnostic costs are harder to compare as a single headline figure than a vaccination or consultation because the appropriate tests depend on your pet's clinical situation. Focus on understanding what each test costs and why it is recommended.

Emergency and out-of-hours diagnostics

In an emergency, diagnostic tests may be recommended quickly to stabilise or assess your pet. Costs are typically part of a wider emergency bill.

Pet care plans

Most monthly pet health plans do not include diagnostic tests such as blood work, X-rays or ultrasound. Plans may include a routine health check, but recommended diagnostics during that check are usually charged separately.
