Calculate Child-Pugh class and MELD score for chronic liver disease severity.
Child-Pugh includes clinical findings such as ascites and encephalopathy while MELD uses only laboratory values, which makes MELD more objective and reproducible. MELD values are clamped at both ends by convention. The two scores answer different questions: Child-Pugh describes current functional compromise while MELD predicts short-term mortality for allocation purposes.
Child-Pugh / MELD Score
Child-Pugh sums five graded variables; MELD = 3.78·ln(bili) + 11.2·ln(INR) + 9.57·ln(creat) + 6.43
This reproduces a published formula for educational and reference use only. It is not a diagnostic tool, does not account for individual clinical context, and must not be used to make or change treatment decisions. Clinical assessment by a qualified healthcare professional is always required. These scores are prognostic aids used by specialists alongside full clinical assessment. Variants such as MELD-Na and MELD 3.0 are now used in some allocation systems.

This calculator takes 6 inputs: Total bilirubin, Serum albumin, INR, Serum creatinine, Ascites, Encephalopathy. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
