The Child-Pugh Calculator is a medical scoring tool used to evaluate the severity of chronic liver disease and predict patient prognosis. It helps healthcare professionals and students quickly assess liver function using five clinical parameters: bilirubin level, albumin level, INR, ascites, and hepatic encephalopathy.

This tool converts medical data into a clear numerical score and classification (Class A, B, or C), helping users understand how advanced liver disease may be. It removes manual calculations and provides instant, structured results that support better clinical decision-making.

Whether you are a medical student, healthcare worker, or someone studying liver conditions, this calculator makes liver assessment faster and easier.

🩺 What Is the Child-Pugh Score?

The Child-Pugh score is a globally recognized medical system used to measure the severity of chronic liver disease, especially cirrhosis. It evaluates liver function based on five key factors:

• Bilirubin level (liver waste processing)
• Albumin level (protein production)
• INR (blood clotting ability)
• Ascites (fluid in abdomen)
• Hepatic encephalopathy (brain function affected by liver disease)

Each parameter is assigned points, and the total score determines liver disease severity:

• Class A (5–6 points): Mild disease
• Class B (7–9 points): Moderate disease
• Class C (10–15 points): Severe disease

The calculator simplifies this process by automatically computing the score.

⚙️ How to Use the Child-Pugh Calculator

Using this tool is simple and requires only basic patient data. Follow these steps:

Step 1: Enter Bilirubin Level

Input the bilirubin value in mg/dL.

Example:

• 1.2 mg/dL (normal or mild elevation)

Step 2: Enter Albumin Level

Enter serum albumin level in g/dL.

Example:

• 3.5 g/dL (normal protein level)

Step 3: Enter INR Value

Provide the INR value to assess blood clotting ability.

Example:

• 1.1 (normal clotting function)

Step 4: Select Ascites Level

Choose the severity of abdominal fluid buildup:

• None
• Mild
• Moderate/Severe

Step 5: Select Hepatic Encephalopathy Grade

Choose the neurological condition level:

• None
• Grade I–II
• Grade III–IV

Step 6: Click “Calculate”

The tool will instantly display:

• Total Child-Pugh score
• Liver disease class (A, B, or C)

Step 7: Copy or Share Results

You can copy or share results with healthcare professionals for further analysis.

📊 Practical Example 1: Early-Stage Liver Disease

A patient shows the following values:

• Bilirubin: 1.5 mg/dL
• Albumin: 3.8 g/dL
• INR: 1.2
• Ascites: None
• Encephalopathy: None

Result:

• Child-Pugh Score: Low
• Class A (Well-compensated liver function)

👉 This indicates mild liver damage and relatively normal liver performance.

---

📊 Practical Example 2: Advanced Liver Cirrhosis

Another patient presents:

• Bilirubin: 3.2 mg/dL
• Albumin: 2.6 g/dL
• INR: 2.0
• Ascites: Moderate
• Encephalopathy: Grade II

Result:

• Child-Pugh Score: High
• Class C (Severe liver dysfunction)

👉 This indicates advanced liver disease requiring urgent medical attention.
