Non-invasive algorithms for gauging liver fibrosis in patients with NAFLD
| 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) www.nafldscore.com |
| Fibrosis-4 (Fib-4) | (age × AST)/(platelets × (√ALT)) https://gps.camdenccg.nhs.uk/fib-4-calculator |
ALT, alanine aminotransferase; AST, aspartate aminotransferase; BMI, body mass index; IFG, impaired fasting glucose; NAFLD, non-alcoholic fatty liver disease.
