PALBI (Platelet-Albumin-Bilirubin) Grade
Platelet-albumin-bilirubin (PALBI) grade for chronic liver disease — the ALBI model augmented with platelet count, stratifying survival into three grades.

Example
- Total bilirubin
- 1.0 mg/dL
- Albumin
- 4.0 g/dL
- Platelet count
- 250 ×10⁹/L
Result: PALBI score -2.21 → grade 2: intermediate liver function.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Grades
- grade 1 (≤ −2.53) best liver function, grade 2 (> −2.53 to −2.09) intermediate, grade 3 (> −2.09) worst. PALBI adds the platelet count to ALBI.
What you enter
- Total bilirubin
- Albumin
- Platelet count
How this is calculated
- Formula
- PALBI = 2.02·log10(bilirubin µmol/L) − 0.37·(log10 bilirubin)² − 0.04·(albumin g/L) − 3.48·log10(platelets 10⁹/L) + 1.01·(log10 platelets)²; entered here in mg/dL and g/dL and converted internally.
