What does the Child-Pugh score measure?

It grades chronic liver disease or cirrhosis severity using bilirubin, albumin, INR, ascites, and hepatic encephalopathy.

What is the Child-Pugh score range?

The total ranges from 5 to 15, with each of the five parameters scored from 1 to 3.

How are Child-Pugh classes defined?

Class A is 5–6, Class B is 7–9, and Class C is 10–15.

Can I enter bilirubin in µmol/L?

Yes. Select µmol/L, and the tool converts the value to mg/dL by dividing by 17.1.

Is the Child-Pugh result medical advice?

No. The result is an informational calculation and should not replace assessment by a qualified healthcare professional.

Child-Pugh Score (Cirrhosis Severity)

Calculate the Child-Pugh score to grade chronic liver disease / cirrhosis severity and estimate perioperative mortality. Five parameters scored 1–3 each (total 5–15): Total bilirubin (<2 mg/dL =1, 2–3 =2, >3 =3) — supports mg/dL or µmol/L input (auto ÷17.1); Serum albumin (>3.5 g/dL =1, 2.8–3.5 =2, <2.8 =3); INR (<1.7 =1, 1.7–2.3 =2, >2.3 =3); Ascites (absent =1, slight/controlled =2, moderate–severe =3); Hepatic encephalopathy (none =1, grade I–II =2, grade III–IV =3). Classes: A (5–6) well-compensated (1-y ~100%, 2-y ~85%); B (7–9) significant compromise (1-y ~80%, 2-y ~60%); C (10–15) decompensated (1-y ~45%, 2-y ~35%). Derived from Pugh et al. 1973 (Br J Surg) and the original Child-Turcotte classification. Not medical advice.
