NAFLD Fibrosis Score — Non-Alcoholic Fatty Liver Disease

Calculate the NAFLD Fibrosis Score using age, BMI, hyperglycemia, platelet count, albumin, and AST/ALT ratio to predict advanced fibrosis in non-alcoholic fatty liver disease.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate the NAFLD Fibrosis Score using age, BMI, hyperglycemia, platelet count, albumin, and AST/ALT ratio to predict advanced fibrosis in non-alcoholic fatty liver disease

Each component has a specific meaning:

  • Age — The age recorded for the scenario being assessed.
  • BMI — The bmi recorded for the scenario being assessed.
  • Hyperglycemia — The hyperglycemia recorded for the scenario being assessed.
  • Platelet count — The platelet count recorded for the scenario being assessed.
  • Albumin — The albumin recorded for the scenario being assessed.
  • AST/ALT ratio — The ast/alt ratio recorded for the scenario being assessed.

Note: Interpret the nafld fibrosis score result against the thresholds and context described above.

How to Use

Enter the age, BMI, hyperglycemia, platelet count, albumin, AST/ALT ratio for the scenario you are assessing. Calculate the NAFLD Fibrosis Score using age, BMI, hyperglycemia, platelet count, albumin, and AST/ALT ratio to predict advanced fibrosis in non-alcoholic fatty liver disease. Use the nafld fibrosis score result to inform your calculation.
