The Enhanced Liver Fibrosis (ELF) test is a specialised blood test that measures a combination of biomarkers associated with liver fibrosis, the process of scarring that occurs when the liver is repeatedly injured or inflamed.
The test analyses three key markers involved in extracellular matrix turnover and fibrotic activity: Hyaluronic Acid (HA), Procollagen III N-terminal peptide (PIIINP), and Tissue Inhibitor of Metalloproteinase-1 (TIMP-1). These are combined into a single ELF score.
Unlike liver biopsy, the ELF test is non-invasive, reproducible, and suitable for monitoring liver health over time.
Liver fibrosis often develops silently and may progress to cirrhosis before symptoms appear. Early detection allows intervention before irreversible damage occurs.
You may need an ELF test if you:
Conditions associated with liver fibrosis include:
You can access Enhanced Liver Fibrosis testing UK-wide through two options:
Your blood sample is analysed in an accredited UK laboratory and an ELF score is calculated.
Low ELF score – minimal fibrosis
Indicates little or no liver scarring.
Typical UK interpretation:
Moderate ELF score – developing fibrosis
Suggests ongoing fibrotic activity and increased risk.
Typical UK interpretation:
High ELF score – advanced fibrosis
Indicates significant liver scarring with risk of progression to cirrhosis.
Typical UK interpretation:
Cut-offs may vary slightly by clinical guideline and population.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
