The Child-Pugh Score Calculator is a medical assessment tool used to evaluate the severity of chronic liver disease, particularly cirrhosis. Healthcare professionals commonly use this scoring system to determine the prognosis of liver disease and guide treatment decisions, including the need for liver transplantation.

This calculator simplifies the process by allowing users to input five clinical factors—bilirubin, albumin, INR, ascites, and hepatic encephalopathy—to determine a Child-Pugh score and classification. Within seconds, the tool calculates the total score and categorizes the liver disease into Class A, Class B, or Class C, indicating the level of liver dysfunction.

Whether you are a healthcare professional, medical student, or someone learning about liver health, this calculator helps provide quick insights into the severity of liver disease.

What Is the Child-Pugh Score?

The Child-Pugh score is a widely used clinical scoring system that evaluates how well the liver is functioning. It helps doctors estimate the prognosis and survival rate for patients with chronic liver conditions.

The score is based on five important medical indicators:

• Bilirubin level (indicates liver’s ability to remove waste)
• Albumin level (reflects liver protein production)
• INR (measures blood clotting ability)
• Ascites (fluid buildup in the abdomen)
• Hepatic encephalopathy (brain function changes due to liver disease)

Each parameter is assigned a score between 1 and 3, and the total determines the severity classification.

Step-by-Step Guide: How to Use the Child-Pugh Score Calculator

Using this calculator is straightforward and takes only a few seconds.

Step 1: Select Bilirubin Level

Choose the bilirubin range that matches the patient’s laboratory result.

Typical ranges include:

• Less than 2 mg/dL
• 2–3 mg/dL
• More than 3 mg/dL

Step 2: Select Albumin Level

Choose the albumin level from the available ranges.

Albumin is a protein produced by the liver, and low levels indicate impaired liver function.

Step 3: Choose INR Value

Select the appropriate INR (International Normalized Ratio) range.

This measures how well the blood clots, which can be affected by liver disease.

Step 4: Select Ascites Severity

Ascites refers to fluid accumulation in the abdomen.

Options typically include:

• None
• Mild
• Moderate or severe

Step 5: Choose Hepatic Encephalopathy Level

This describes the severity of brain dysfunction caused by liver disease.

Levels include:

• None
• Grade 1–2
• Grade 3–4

Step 6: Click “Calculate”

Once all fields are selected, press the Calculate button.

Step 7: Review the Results

The tool will display:

• Total Child-Pugh score
• Classification (A, B, or C)
• Liver disease severity description

Step 8: Copy or Share Results

You can easily copy or share the results for medical records or consultations.

Practical Example

Let’s look at a practical scenario.

Patient Data

• Bilirubin: 2.5 mg/dL
• Albumin: 3.0 g/dL
• INR: 1.9
• Ascites: Mild
• Hepatic Encephalopathy: None

Score Calculation

Each parameter receives a score:

• Bilirubin = 2 points
• Albumin = 2 points
• INR = 2 points
• Ascites = 2 points
• Encephalopathy = 1 point

Total Score

2 + 2 + 2 + 2 + 1 = 9

Final Result

• Child-Pugh Class: B
• Severity: Significant functional compromise

This indicates moderate liver disease, which may require closer monitoring and possible treatment adjustments.

Child-Pugh Classification Explained

The final score determines the class of liver disease.

Class A

Patients have relatively preserved liver function and better prognosis.

Class B

Moderate impairment of liver function requiring medical management.

Class C

Severe liver dysfunction with poor prognosis and often considered for liver transplantation.
