Quick Answer
A private liver function test (LFT) in the UK costs from around £39 for a basic blood test, or £100–£250 for a comprehensive liver panel. You can book an at-home finger-prick or venous kit, or visit a clinic — no GP referral needed — with results often the same day (if tested before noon) or within 1–3 days. An LFT measures key liver enzymes and proteins (ALT, AST, ALP, GGT, bilirubin and albumin) to check for inflammation or damage from causes like alcohol, fatty liver, medication or hepatitis.
This independent 2026 guide explains what’s tested, what the results mean, and how to book — without the hype.
What this guide covers
Want to check your liver health quickly? A private LFT offers fast answers with no waiting. This independent 2026 guide covers the essentials. Going Private UK is editorially independent; we may earn commission when readers compare cover through our links. This is general information, not medical advice.
How much does a private liver function test cost? (2026)
| Option | What’s included | Typical cost (2026) |
|---|---|---|
| Basic LFT (home kit) | Core liver enzymes & bilirubin | £39–£70 |
| Clinic LFT (venous) | Nurse-drawn blood (more reliable) | £60–£100 |
| LFT + private GP appointment | Test plus a consultation | £100–£150 |
| Comprehensive liver panel | + albumin, total protein, sometimes viral/metabolic markers | £120–£250 |
The cheapest at-home finger-prick LFTs start from about £39 (note some providers add a £35–£59 venous-collection fee if you want a clinical-standard draw). A test with a doctor’s review, or a fuller panel adding viral hepatitis and metabolic markers, costs more. London clinics sit at the higher end. For the wider picture, see our private blood test cost guide.
What does a liver function test measure?
An LFT checks a panel of enzymes and proteins that reflect how your liver is working. The standard markers are:
| Marker | What it indicates |
|---|---|
| ALT (alanine transferase) | Key marker of liver-cell damage/inflammation |
| AST (aspartate transferase) | Liver (and muscle) damage |
| ALP (alkaline phosphatase) | Bile-duct, liver or bone issues |
| GGT (gamma-GT) | Sensitive marker, often raised by alcohol & bile-duct disease |
| Bilirubin | Processed by the liver; high levels cause jaundice |
| Albumin & total protein | Proteins the liver makes; reflect longer-term function |
Together these can point to inflammation, bile-duct problems, fatty liver, or damage from alcohol, medication or viral hepatitis. A fuller “liver screen” may add viral serology and an ultrasound to look directly at the liver.
Why do people get a private liver test?
- Symptoms — fatigue, jaundice (yellowing), dark urine, itchy skin, nausea or upper-right abdominal discomfort
- Alcohol or medication monitoring — checking the effect of regular drinking or long-term medicines (GGT is a sensitive alcohol marker)
- Suspected fatty liver, hepatitis or cirrhosis — early detection or monitoring
- Peace of mind / general screening — as part of a wider health check
Some people also need an LFT for a medical or occupational reason (for example, certain DVLA/driving medicals assess liver markers) — check the exact requirements with whoever has requested it.
⚠️ A normal result doesn’t always mean all-clear
Liver damage often develops silently, and LFTs can be normal even in early fatty liver disease. So a normal result is reassuring but not a guarantee — and an abnormal result needs proper interpretation, not panic. If you have symptoms like jaundice, persistent abdominal pain or are worried about your liver, see your GP, who can interpret results in context and arrange further tests if needed.

At-home vs clinic — how to book
You can book directly — no GP referral needed — in two main ways:
- At-home kit (e.g. Medichecks, Thriva, Randox) — a finger-prick or home-phlebotomist sample, posted back; results in 1–3 days with a doctor’s comment. Cheapest and most convenient.
- Clinic / walk-in venous test (private blood-test clinics, Spire, Nuffield) — a nurse takes blood, the clinical gold standard for accuracy; often same-day results if done before noon. See private blood tests London.
Prefer a consultation alongside the test? A private GP can order and interpret it for you.
Understanding your results
You’ll get a report showing each marker against the lab’s reference range, usually with a doctor’s comment. A single mildly raised value isn’t necessarily a problem — results are read together and in context (your alcohol intake, medications, weight and symptoms all matter). A pattern of raised ALT/AST suggests liver-cell inflammation; a raised GGT/ALP can point to bile-duct or alcohol-related issues. Anything abnormal should be discussed with a clinician, who may repeat it or arrange further tests. Results usually arrive same-day to 1–3 days.
Does health insurance cover liver function tests?
Usually only when medically indicated and referred — i.e. you have symptoms and a private GP or specialist orders the test as part of investigating a condition, under your outpatient benefits. A routine self-ordered “check my liver” test with no symptoms generally isn’t claimable, and not all policies include blood tests by default. See does insurance cover blood tests? and does Bupa cover blood tests?
The bottom line
A private liver function test is cheap (from ~£39), fast (often same-day) and needs no referral — a convenient way to check your liver health, whether you have symptoms, want to monitor the effects of alcohol or medication, or just want reassurance. Just remember a normal LFT doesn’t completely rule out early liver disease, and any abnormal result should be interpreted by a clinician rather than acted on alone.

Frequently Asked Questions
How much does a private liver function test cost in the UK?
From around £39 for a basic at-home LFT, £60–£100 for a clinic venous test, £100–£150 with a private GP appointment, and £120–£250 for a comprehensive liver panel. Some home-kit providers add a £35–£59 fee for a clinical-standard venous draw. London clinics tend to be at the higher end.
Do I need a GP referral for a private liver test?
No — you can order an at-home kit or book a clinic test directly, with no referral. If you want to claim on insurance, however, you’ll usually need symptoms, a referral, and the test to be part of investigating a condition.
What does a liver function test check?
It measures liver enzymes and proteins — ALT, AST, ALP, GGT, bilirubin, and usually albumin and total protein. These reflect inflammation, bile-duct problems and overall liver function, and can flag damage from alcohol, fatty liver, medication or viral hepatitis.
Can a liver function test detect alcohol damage?
It can suggest it — GGT in particular is a sensitive marker that’s often raised by regular alcohol use, alongside raised ALT/AST. However, LFTs aren’t a specific “alcohol test”, and results need interpreting in context. For driving or occupational medicals, specific markers may be required — check the exact requirement.
How quickly will I get my results?
Often the same day if a clinic test is done before noon, or within 1–3 days for home kits, usually with a doctor’s comment. You can then share the report with your GP or a private GP if anything needs following up.
Can my liver test be normal and still have a problem?
Yes — liver damage can develop silently, and LFTs can be normal even in early fatty liver disease. A normal result is reassuring but not a guarantee. If you have symptoms or risk factors, see your GP, who may arrange an ultrasound or further tests despite a normal LFT.
