The child pugh calculator works out result from international normalised ratio (inr), serum albumin, ascites, total bilirubin and encephalopathy. Enter what you have and the relationship is applied straight away, so you get the answer without working through the algebra yourself.
What Is the Child Pugh Calculator?
The child pugh calculator gives you an estimate of result based on international normalised ratio (inr), serum albumin, ascites, total bilirubin and encephalopathy.
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the Child Pugh Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.

A Worked Example
Working through an example, with international normalised ratio (inr) set to 1, serum albumin set to 1, ascites set to 1, the calculator returns result of 11,111. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out result?
Enter international normalised ratio (inr), serum albumin, ascites, total bilirubin and encephalopathy. The calculator then works through the relationship and reports result.
What does the child pugh actually calculate?
It takes international normalised ratio (inr), serum albumin, ascites, total bilirubin and encephalopathy and converts them into result using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter international normalised ratio (inr)?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
