HSI Components
Calculation Method
HSI Formula:
HSI = 8 × (ALT/AST) + BMI + 2 (if female) + 2 (if diabetes)
Where:
• ALT = Alanine aminotransferase level
• AST = Aspartate aminotransferase level
• BMI = Body mass index
• Gender: Female = 2, Male = 0
• Diabetes: Yes = 2, No = 0
• HSI = 0
HSI Interpretation
HSI < 30: Low probability of fatty liver disease
HSI 30-36: Intermediate probability of fatty liver disease
HSI > 36: High probability of fatty liver disease
Note: HSI is a screening tool and should not replace clinical evaluation or imaging studies.
