-1.675 + 0.037 × age (years) + 0.094 × BMI (kg/m2) + 1.13 × IFG/diabetes (yes = 1, no = 0) + 0.99 × AST/ALT ratio – 0.013 × platelet (×109/l) – 0.66 × albumin (g/dl)

The NAFLD Fibrosis score is a non-invasive scoring system based on several laboratory tests that help to estimate the amount of scarring in the liver. This score has been studied in liver disease NAFLD only.

NAFLD Score < -1.455 = F0-F2
NAFLD Score -1.455 – 0.675 = indeterminate score
NAFLD Score > 0.675 = F3-F4
