ALBI Score Calculator
The ALBI Score Calculator is a powerful medical assessment tool used to evaluate liver function based on two important blood parameters: Albumin (g/L) and Bilirubin (µmol/L). It is widely used in clinical research and healthcare settings to assess liver disease severity, especially in patients with chronic liver conditions such as cirrhosis and hepatocellular carcinoma.
Unlike traditional scoring systems that include multiple subjective factors, the ALBI (Albumin-Bilirubin) score is completely objective. It relies only on laboratory values, making it more consistent and easier to use in both clinical practice and online health tools.
This calculator helps users instantly determine:
- ALBI Score (numerical value)
- ALBI Grade (risk classification)
- Liver function status (low, moderate, or high risk)
It is especially useful for doctors, medical students, researchers, and healthcare professionals who need quick liver function assessment without manual calculations.
What is ALBI Score?
The ALBI Score (Albumin-Bilirubin Score) is a scientific formula developed to evaluate liver function more accurately than traditional methods. It was originally introduced to improve patient assessment in liver cancer cases but is now widely used in hepatology.
The ALBI score focuses on two key biomarkers:
1. Albumin
- A protein produced by the liver
- Indicates liver’s ability to synthesize proteins
- Low levels suggest poor liver function
2. Bilirubin
- A waste product processed by the liver
- High levels indicate liver dysfunction or bile obstruction
By combining these two values, the ALBI score provides a clear picture of liver health.
How to Use the ALBI Score Calculator
Using the ALBI Score Calculator is simple and requires only a few steps:
Step 1: Enter Albumin Value

ALBI Score Formula Explained
The ALBI score is calculated using a scientifically developed formula:
ALBI Formula:
ALBI Score = (Log10(Bilirubin) × 0.66) + (-0.085 × Albumin)
Breaking Down the Formula
1. Logarithmic Component (Bilirubin)
- The bilirubin value is converted using log base 10
- This helps normalize large variations in bilirubin levels
2. Albumin Coefficient
- Albumin is multiplied by -0.085
- This negative value reflects that higher albumin indicates better liver function
3. Combined Result
- Both values are added together to produce the final ALBI score
- Lower scores indicate better liver function
ALBI Grading System
Once the ALBI score is calculated, it is categorized into three grades:
ALBI Grade 1 (Low Risk)
- Score ≤ -2.60
- Indicates good liver function
- Minimal liver impairment
ALBI Grade 2 (Moderate Risk)
- Score between -2.60 and -1.39
- Indicates moderate liver dysfunction
- Requires medical monitoring
ALBI Grade 3 (High Risk)
- Score > -1.39
- Indicates severe liver dysfunction
- Requires immediate clinical attention
Example of ALBI Score Calculation
Let’s understand how the calculator works with a real example:
Patient Data:
- Albumin = 38 g/L
- Bilirubin = 20 µmol/L
Step 1: Apply Formula
ALBI Score = (Log10(20) × 0.66) + (-0.085 × 38)
Step 2: Calculate Values
- Log10(20) ≈ 1.301
- 1.301 × 0.66 = 0.858
- -0.085 × 38 = -3.23
Step 3: Final Score
ALBI Score = 0.858 - 3.23 = -2.372
Step 4: Determine Grade
- Score = -2.372
- Falls between -2.60 and -1.39
- ALBI Grade = Grade 2 (Moderate Risk)
Why ALBI Score is Important
The ALBI score is widely used in medical science because it offers several advantages:
1. Completely Objective
No subjective interpretation is required, unlike older scoring systems.
2. Easy to Calculate
Only two laboratory values are needed.
3. Clinically Reliable
Widely validated in liver disease research.
4. Useful in Cancer Staging
Helps assess liver function in hepatocellular carcinoma patients.
5. Better Accuracy
Provides more precise liver function evaluation than traditional scoring methods.
Medical Applications of ALBI Score
The ALBI score is used in various healthcare scenarios:
- Liver cirrhosis evaluation
- Hepatocellular carcinoma staging
- Pre-surgical liver function assessment
- Chronic liver disease monitoring
- Clinical research studies
- Treatment planning for liver patients
Limitations of ALBI Score
While highly useful, the ALBI score has some limitations:
- Does not include clinical symptoms
- Cannot replace full liver function tests
- Should be interpreted with medical guidance
- Not suitable as a standalone diagnostic tool
Tips for Accurate Results
To ensure correct ALBI score calculation:
- Always use accurate lab results
- Ensure correct units (g/L and µmol/L)
- Avoid estimated or rounded medical values
- Consult healthcare professionals for interpretation
- Combine with other liver tests for complete diagnosis
