Why this matters
FIB-4 identifies patients with significant liver fibrosis from conditions like non-alcoholic fatty liver disease, chronic hepatitis, or alcohol-related liver disease before symptoms appear. Early detection through FIB-4 screening enables lifestyle modifications (weight loss, alcohol cessation), medication adjustments, and closer monitoring to prevent progression to cirrhosis, liver failure, or hepatocellular carcinoma.
