Non-Alcoholic Fatty Liver Disease (NAFLD) Fibrosis Score Calculator

The Non-Alcoholic Fatty Liver Disease (NAFLD) Fibrosis Score Calculator estimates the amount of scarring in the liver base on several laboratory tests.

The NAFLD Fibrosis Score is calculated as follows:

NAFLD Fibrosis Score = −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)).

NAFLD Score	Correlated Fibrosis Severity
< -1.455	F0	No Fibrosis
	F1	Mild Fibrosis
	F2	Moderate Fibrosis
-1.455 > < 0.675	Indeterminate Score
> 0.675	F3	Severe Fibrosis
	F4	Cirrhosis
