Child-Pugh Score Calculator

The Child-Pugh score grades the severity of chronic liver disease (cirrhosis) into class A, B or C from five factors: bilirubin, albumin, INR, ascites and hepatic encephalopathy.

Quick answer

The Child-Pugh score grades cirrhosis severity from five factors β€” bilirubin, albumin, INR, ascites and hepatic encephalopathy β€” each scored 1 to 3, for a total of 5 to 15. It classifies disease as class A (5–6, well-compensated), B (7–9), or C (10–15, decompensated).

Child-Pugh inputs

How to use the Child-Pugh calculator

  1. 1Enter bilirubin, albumin and INR. Enter the bilirubin, albumin and INR values; the tool assigns 1–3 points per band.
  2. 2Select ascites and encephalopathy. Select the ascites grade (none / mild / moderate) and hepatic encephalopathy grade (none / I–II / III–IV).
  3. 3Read the class. The tool totals 5–15 points and shows the Child-Pugh class (A, B or C) for prognosis and procedural-risk discussion.

Frequently asked questions

What do Child-Pugh classes A, B and C mean?βŒ„

Class A (5–6 points) is well-compensated cirrhosis with the best prognosis; class B (7–9) is significant functional compromise; class C (10–15) is decompensated disease with the poorest prognosis.

How is Child-Pugh different from MELD?βŒ„

Child-Pugh uses two subjective items (ascites and encephalopathy) and grades into three classes; MELD is fully objective (lab-based) and gives a continuous score used for transplant allocation. Both assess liver disease severity.

What is Child-Pugh used for?βŒ„

It estimates prognosis in cirrhosis and helps assess the risk of surgery, medications metabolised by the liver, and procedures.
