How to Use the Child Pugh Score Calculator
- Enter Bilirubin (mg/dL) – e.g., 1.5. Use decimal values if needed.
- Enter Albumin (g/dL) – e.g., 3.0. Must be a positive number.
- Enter INR – e.g., 1.5. This is a unitless ratio.
- Select Ascites – Choose from: None, Mild (detectable on imaging), or Moderate to Severe (tense).
- Select Encephalopathy – Choose from: None, Grade 1-2 (mild), or Grade 3-4 (severe).
- Click Calculate Score – The result will show your total score (5–15), Child Pugh class (A, B, or C), and a brief clinical interpretation.
All inputs are required. Negative values are invalid. The score helps assess liver disease severity and operative risk.

Frequently Asked Questions
The Child Pugh score is a clinical tool used to assess the severity of liver disease, particularly cirrhosis, and predict prognosis. It uses five clinical measures: total bilirubin, serum albumin, INR, ascites, and hepatic encephalopathy.
Each of the five parameters is scored from 1 to 3 points, with 1 being the least abnormal and 3 being the most abnormal. The total score ranges from 5 to 15, and patients are classified into Class A (5-6), B (7-9), or C (10-15).
Class A indicates well-compensated liver disease with good hepatic function. Class B indicates significant functional compromise. Class C indicates decompensated liver disease with poor prognosis. Higher classes are associated with increased surgical risk and shorter survival.
