NAFLD Fibrosis Score

Advanced fibrosis risk in fatty liver disease.

Education and reference only. Not a substitute for clinical judgement, local policy or product labelling. Always verify before clinical use. Values are calculated in your browser and never stored.

When to use

Use in non-alcoholic fatty liver disease to estimate the likelihood of advanced (F3–F4) fibrosis.

Why use

It helps decide who needs specialist assessment or further fibrosis testing.

Critical actions

Albumin in g/dL (divide g/L by 10). Cut-offs: <−1.455 and >0.675. The indeterminate zone is common; pair with elastography or FIB-4.
