The Liver Function Test, or LFT, is performed to assess how well your liver is working and to detect any liver disease, inflammation, or damage. This test measures key enzymes and proteins to detect early signs of liver damage, giving insights into complete liver functioning and health. The National Blood Test Clinic is trusted across the UK for accurate and reliable Liver Blood Tests.

If you're experiencing constant fatigue, loss of appetite, jaundice, or bloating/swelling issues, you must get your Liver Test done. Further, people with a family history of liver disease or diabetes, hepatitis, AUD (Alcohol Use Disorder), or obesity must consider monitoring their LFTs regularly.

What Gets Tested

This test examines multiple biomarkers to evaluate liver health, inflammation, and overall protein balance.

Markers included:

  • ALT - Alanine Aminotransferase
  • ALT - Aspartate  Aminotransferase
  • ALP - Alkaline Phosphatase
  • GGT - Gamma-Glutamyl Transferase

What This Liver Test Measures

Liver Enzymes
  • ALT & AST: Elevated levels can indicate liver damage or inflammation.
  • ALP & GGT: Linked to bile flow and liver enzyme function — often raised with excessive alcohol intake or gallbladder issues
Bilirubin & Protein Levels
  • Total Bilirubin: A waste product from red blood cell breakdown — high levels may cause jaundice or signal bile duct issues.
  • Albumin, Globulin & Total Protein: Indicate liver’s ability to produce essential proteins and maintain fluid balance.
This test helps identify
  • Liver damage or inflammation
  • Fatty liver or alcohol-related stress
  • Hepatitis or bile duct problems
  • Protein synthesis or metabolic concerns

How To Use The Home Test Kit

Frequently Asked Questions (FAQs)

Why is liver function important?

Your liver filters toxins, processes nutrients, regulates hormones, and supports digestion. Impaired liver health can affect your entire body.

What causes high liver enzymes?

Common causes include alcohol consumption, medications, obesity, viral
hepatitis, or autoimmune conditions.

Can this test diagnose liver disease?

It can detect signs of liver stress or damage, but diagnosis should always be
confirmed by a healthcare provider with additional testing if needed.

Do I need to fast for this test?

Fasting isn’t required, but avoiding alcohol for 24 hours beforehand is recommended.

Can I take this test while on medication?

Yes but it’s helpful to note your medications, as some may influence enzyme levels.

Can a Liver Function Test be performed at home?

Yes, a Liver Function Test can be performed at home using a reliable liver test kit. In a home liver test, a small blood sample is collected using a finger-prick testing technique and sent to a certified lab for analysis. You will get the test reports within 2-3 days.

What do the Liver Function Blood Test results indicate?

Liver function test results help assess how well your liver is working. Abnormal liver function test results may indicate inflammation, liver damage, or conditions like hepatitis or fatty liver. These liver blood test results are interpreted by measuring enzymes and proteins in your blood. A proper liver function test interpretation helps diagnose issues early and monitor ongoing liver health.

What if my LFTs report is abnormal?

Abnormal liver blood test results are usually common, which may appear due to an infection or as a side effect of certain medications. If your blood reports for LFTs detect some abnormality, it's important to consult your doctor for advice and follow-up guidance. He may refer to further testing, CT or MRI scans, to understand the reason and extent of liver damage.

What tests do I need for non-alcoholic fatty liver disease?

Non-alcoholic fatty liver disease (NAFLD) is a common condition in the United Kingdom, affecting approximately 30–40% of the population. It is often linked to obesity, making weight loss through a healthy diet and regular exercise the primary approach for managing the condition. To diagnose or monitor NAFLD, your doctor may recommend liver function tests, imaging scans, or a Fibro Scan to assess liver health.
