Child Pugh Score Calculator

Child-Pugh Score Calculator – Assess Liver Disease Severity

The Child-Pugh Score Calculator is a clinical tool used to evaluate the severity and prognosis of chronic liver disease, particularly cirrhosis. It helps healthcare providers estimate patient survival and determine the need for treatments such as liver transplantation.


What Is the Child-Pugh Score?

Originally developed to predict surgical risk in patients with liver disease, the Child-Pugh Score (also known as the Child-Turcotte-Pugh score) evaluates liver function using five key clinical and laboratory measurements.


Child-Pugh Score Criteria

The calculator uses the following five parameters:

  1. Total Bilirubin
  2. Serum Albumin
  3. INR (Prothrombin Time)
  4. Ascites (abdominal fluid buildup)
  5. Hepatic Encephalopathy (mental confusion caused by liver failure)

Each parameter is scored from 1 to 3 points based on severity. The total score classifies patients into three categories:

Total Score Class Liver Disease Severity 5–6 A Mild (well-compensated) 7–9 B Moderate (significant) 10–15 C Severe (decompensated) Why Use the Child-Pugh Calculator?

  • Predicts liver-related mortality
  • Assesses need for liver transplantation
  • Helps guide treatment decisions
  • Supports prognosis discussions with patients

It is commonly used in hepatology, oncology, and gastroenterology to manage chronic liver conditions and cirrhosis from hepatitis, alcohol abuse, non-alcoholic fatty liver disease (NAFLD), or autoimmune causes.


How It Works

Each component is assigned a point:

Parameter 1 Point 2 Points 3 Points Bilirubin (mg/dL) <2 2–3 >3 Albumin (g/dL) >3.5 2.8–3.5 <2.8 INR <1.7 1.7–2.3 >2.3 Ascites None Mild (controlled) Moderate to severe (poorly controlled) Encephalopathy None Grade I–II (mild/moderate) Grade III–IV (severe/comatose) Once calculated, the total score is used to classify the disease.


Who Should Use This Tool?

  • Hepatologists and gastroenterologists
  • Liver transplant teams
  • Oncologists managing liver metastasis
  • Medical residents and students
  • Clinics or websites offering medical tools


Common Questions

Is the Child-Pugh score accurate?

It is widely accepted in clinical practice but has limitations. MELD score is often used alongside it for liver transplant prioritization.

Does it replace the need for lab tests?

No. The Child-Pugh Score combines lab results with clinical findings. It supports, not replaces, physician judgment.

Can patients use it themselves?

It’s intended for use by healthcare professionals. However, informed patients may use it under guidance to understand their condition better.


The Child-Pugh Score Calculator is a trusted tool for grading chronic liver disease and cirrhosis. By combining lab values and clinical observations, it guides treatment plans, transplant decisions, and prognosis.

Whether you're a healthcare provider or operate a medical site, offering this calculator helps support informed, evidence-based decisions in liver disease management.
