SELFCheck Liver Health Test

A quick, private at-home finger-prick test that screens for raised ALT and AST — two key liver enzymes — with a result in under 10 minutes.

The SELFCheck Liver Health Test screens for elevated levels of two liver enzymes, ALT (alanine transaminase) and AST (aspartate transaminase), using a small finger-prick blood sample. Raised levels of either enzyme can be an early sign that the liver is under strain — from factors such as alcohol intake, excess weight, certain medications, or other underlying conditions — often before any symptoms appear.

The test is a manual, lateral-flow (immunochromatographic) screening device, registered as a CE-marked in-vitro diagnostic device for self-testing. It’s designed to give a quick preliminary read on liver health in the privacy of your own home, rather than a full laboratory diagnosis.

Key Features

• Screens for two key liver enzymes: ALT and AST
• Results in under 10 minutes
• Simple finger-prick sample — no need to visit a clinic
• CE-marked in-vitro diagnostic self-test
• Discreet, private testing at home
• Contains 1 test

How It Works

1. Take a small blood sample from a finger prick using the lancet provided.
2. Apply the sample to the test device as directed in the enclosed instructions.
3. Read your result within the stated time window (typically around 10 minutes).
4. Follow up with your GP if your result is raised or if you have any symptoms or concerns.

Understanding Your Result

Normal result: No raised ALT/AST detected at the time of testing. This is reassuring but doesn’t rule out all liver conditions, and doesn’t replace regular check-ups if you have risk factors.

Raised result: Indicates elevated liver enzymes, which can point to several possible causes. This is a starting point for a conversation with your GP, not a diagnosis — further blood tests are needed to understand what’s causing it.

A self-test result — whether normal or raised — should always be discussed with a doctor if you have symptoms or ongoing concerns about your liver health.

Who Might Consider This Test

• Anyone wanting a general check-in on liver health
• People monitoring the effect of alcohol intake or lifestyle changes over time
• Those with risk factors such as being overweight, or taking medications that can affect the liver
• Anyone who wants a private, at-home first step before deciding whether to see a GP

Important Information

• This is a screening test, not a diagnostic test — it cannot diagnose liver disease on its own.
• Always read the full instructions for use included in the pack before testing.
• For single use only.
• Store as directed on the packaging and check the expiry date before use.
• If you have any symptoms of liver problems (such as persistent fatigue, abdominal pain, yellowing of the skin or eyes, or dark urine), speak to your doctor regardless of your test result.

FAQs

What does this test actually measure?
It checks for raised levels of ALT and AST, two enzymes that are released into the blood when the liver is inflamed or under strain.

How accurate is the test?
It’s designed as a preliminary screening tool with a high level of agreement with standard laboratory testing, though it isn’t a substitute for a full clinical liver function test.

Do I need to fast before testing?
Check the instructions included with your specific kit, as requirements can vary — some home tests recommend avoiding food or alcohol for a set period beforehand.

What should I do if my result is raised?
Book an appointment with your GP. A raised result on its own isn’t a diagnosis, but it’s a reason to get a full blood test and discuss your liver health with a professional.

Can this replace a GP liver function test?
No — it’s designed as a convenient first-step screening tool, not a replacement for clinical testing or medical advice.
