Bonacini Cirrhosis Discriminant Score
Bonacini cirrhosis discriminant score (Bonacini M, et al. Am J Gastroenterol 1997): platelets, ALT/AST ratio, and INR each binned to points for a 0-11 total, where <= 3 makes cirrhosis unlikely and >= 8 likely.

Example
- Platelet count
- 90 10^3/uL
- ALT / AST ratio
- 0.5
- INR
- 1.5
Result: Bonacini score 10 — cirrhosis likely (>= 8).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- <= 3
- Cirrhosis unlikely.
- 4-7
- Indeterminate.
- >= 8
- Cirrhosis likely (platelets, ALT/AST ratio, INR binned to points). A discriminant score, not a diagnosis.
What you enter
- Platelet count
- ALT / AST ratio
- INR
