APRI Score CalculatorBy Dr. Costa / October 11, 2025 APRI Score Calculator (Auto)APRI Score CalculatorFormula: APRI = (AST ÷ ULN) × 100 ÷ Platelets (10⁹/L). AST (U/L) AST Upper Limit of Normal (ULN, U/L) Platelets ×10⁹/L×10³/µL Note: ×10³/µL is numerically equivalent to ×10⁹/L (no conversion needed). APRI: — Interpretation: — Enter AST, ULN, and platelets; the score updates automatically. Common cutoffs (esp. chronic hepatitis C): <0.5 low likelihood of significant fibrosis; 0.5–1.0 indeterminate; >1.0 suggests significant fibrosis; ≥2.0 suggests cirrhosis. Cutoffs vary by population/etiology.For education only — not medical advice.
