Calculate ALBI Score
What is the ALBI score?
The Albumin-Bilirubin score, commonly called ALBI score, is an objective liver function score based only on serum albumin and total bilirubin.
It was developed mainly for prognostic assessment in hepatocellular carcinoma, but it is also used in hepatology research and clinical risk stratification because it avoids subjective variables such as ascites and encephalopathy.
ALBI score formula
The ALBI score is calculated from total bilirubin expressed in µmol/L and albumin expressed in g/L.
A lower ALBI score reflects better preserved liver function, while a higher score indicates more impaired liver function.
ALBI score interpretation
Supported units
- Bilirubin units: µmol/L, mg/dL, mg/L and µg/mL.
- Albumin units: g/L, g/dL, g/100mL, g%, mg/dL and mg/L.
- The calculator automatically converts bilirubin to µmol/L and albumin to g/L before applying the ALBI formula.
- This helps compare results from laboratories that report albumin and bilirubin using different unit systems.
Important limitations
The ALBI score is useful, but it is not a complete assessment of liver disease.
- It does not diagnose hepatocellular carcinoma, cirrhosis or liver failure.
- It should not be used as the only criterion for treatment decisions.
- Bilirubin and albumin may be affected by non-hepatic factors such as hemolysis, inflammation, malnutrition, nephrotic syndrome or acute illness.
- Always interpret the score with the patient history, imaging, coagulation profile, kidney function and specialist assessment when needed.
