Formula, assumptions, and example
Formula: Child–Pugh total = bilirubin points + albumin points + INR points + ascites points + encephalopathy points; totals range from 5 to 15.
The calculator adds the five one-to-three point components and assigns the conventional A, B, or C class context. Ascites and encephalopathy are clinical judgments, so their selections are not inferred from laboratory values.
- Laboratory results are entered in the units and ranges shown by the selected scoring convention.
- The INR branch is used instead of the alternative prothrombin-time-prolongation branch.
- Bilirubin, albumin, and INR boundaries follow the cited Child–Turcotte–Pugh table.
- Ascites and encephalopathy are selected from documented clinical assessment, not guessed by the calculator.
- Each of the five parameters contributes one, two, or three points.
- Class A, B, and C are classification contexts and do not provide an individual prognosis or treatment recommendation.
- The score does not include renal function, sodium, etiology, transplant eligibility, or other disease information.
- Follow the local hepatology protocol and qualified clinician’s interpretation when a current score is needed.
Worked example: Child–Pugh total = 1 + 1 + 1 + 1 + 1 = 5 points, class A context.

How to use the Child–Pugh Liver Function Score Calculator for a real question
Add the five Child–Turcotte–Pugh components—bilirubin, albumin, INR, ascites, and encephalopathy—with the class boundaries and subjective fields clearly separated. Start with one clearly defined goal, enter values in the units shown, and keep the result attached to the assumptions below.
What this answers
This tool is useful when your question includes Child Pugh calculator, Child Turcotte Pugh score, CTP score. It returns the outputs declared in the calculator contract rather than a live quote, approval, diagnosis, or professional sign-off.
What you enter
Total bilirubin · Serum albumin · INR · Ascites context · Hepatic encephalopathy context. Keep the same time period, unit system, and currency wherever the form requires comparable values.
How to check it
Run the worked example first, compare its output with the page's example, then change one input at a time. This makes an unexpected result easier to trace to a unit, boundary, or assumption.
Three checks before you rely on the answer
- Match the question. Confirm that the result means the quantity you need, not a similar-sounding percentage, balance, rate, or estimate.
- Match the inputs. Use the requested units and period, and read each hint before replacing the example values with your own.
- Read the boundary. Review the assumptions and limits. Laboratory results are entered in the units and ranges shown by the selected scoring convention.

Context and background
How health estimates should be read
Health calculators use measurements and population-level relationships to produce screening or planning estimates. They describe the supplied model; they do not diagnose, prescribe, or replace clinical judgment.
Many familiar health formulas began as practical ways to summarize measurements. Their limits matter as much as their output because individual bodies, medications, conditions, and professional standards vary.
Research and review
How this guide was researched
Researched by Hassan ALRowaie, Founder and editorial researcher at WorldCalculate.
This guide follows the live calculator's declared inputs, formula, worked example, assumptions, validation boundaries, and source-backed methodology. The review date describes editorial review of the calculator explanation; it is not a promise that external facts or rates remain current.
The Child–Turcotte–Pugh score combines laboratory results with two clinical findings to classify the severity context of cirrhosis. WorldCalculate keeps every point visible and avoids pretending that the subjective fields can be inferred from numbers.
What the Child–Pugh score measures
The score uses total bilirubin, serum albumin, INR, ascites, and hepatic encephalopathy. Each component contributes one to three points.
The total ranges from 5 to 15, and the conventional class boundaries are A for 5–6, B for 7–9, and C for 10–15.
Laboratory components
Bilirubin and albumin reflect different aspects of liver-related physiology, while INR represents the selected coagulation component in this version.
Enter the documented result in the correct unit and confirm whether the local protocol uses a different table or a prothrombin-time-prolongation branch.
Ascites is a clinical assessment
Ascites is not scored by simply entering a fluid volume. The instrument distinguishes absent, mild or moderate, and severe or refractory clinical contexts.
Treatment response and the responsible clinician’s documented assessment matter. The calculator does not decide whether a patient meets one category.
Encephalopathy is also a clinical assessment
The score separates no encephalopathy from lower and higher grade contexts. Neurologic status, precipitating factors, treatment, and clinical examination are essential.
Do not infer encephalopathy from a laboratory value, a user’s online description, or a calculator result.
How to calculate the total
Add one score from each of the five fields. An all-one example is 1 + 1 + 1 + 1 + 1 = 5.
The component breakdown makes it possible to see whether a change came from a lab threshold or from a documented clinical finding.
Understanding classes A, B, and C
Class A, B, and C describe the conventional total-score bands. They are not a complete picture of disease severity, cause, kidney function, infection, nutrition, or current instability.
Different protocols may use different versions or additional tools. The score should be read beside the full clinical record.
Limits of an online worksheet
This page cannot assess a patient, verify laboratory quality, grade encephalopathy, or choose a treatment. It is an arithmetic and teaching aid for an already documented assessment.
Urgent symptoms such as bleeding, confusion, severe sleepiness, vomiting blood, black stools, or breathing difficulty require immediate local care.
FAQs
Does class C diagnose liver failure? No; it is a score class within a specific instrument. Can the calculator decide transplant eligibility? No. Why are two fields not numeric? Ascites and encephalopathy require clinical assessment rather than an invented numeric shortcut.

What are the limits of this calculator?
Laboratory results are entered in the units and ranges shown by the selected scoring convention. The INR branch is used instead of the alternative prothrombin-time-prolongation branch. Bilirubin, albumin, and INR boundaries follow the cited Child–Turcotte–Pugh table. Ascites and encephalopathy are selected from documented clinical assessment, not guessed by the calculator. Each of the five parameters contributes one, two, or three points. Class A, B, and C are classification contexts and do not provide an individual prognosis or treatment recommendation.
