FibroQ (Liver Fibrosis Index)
FibroQ (Hsieh 2009): 10 × (age × AST × INR) / (ALT × platelets); a value > 1.6 predicts significant fibrosis (≥ F2).

Example
- Age
- 50 years
- AST
- 80 IU/L
- INR
- 1.2
- ALT
- 40 IU/L
- Platelet count
- 150 ×10⁹/L
Result: FibroQ 8 — significant fibrosis likely (> 1.6).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- <= 1.6
- Significant fibrosis unlikely.
- > 1.6
- Significant fibrosis (>= F2) likely. FibroQ = 10 x (age x AST x INR) / (ALT x platelets). A non-invasive marker, not a biopsy order.
What you enter
- Age
- AST
- INR
- ALT
