About this calculator

This calculator computes the MELD (Model for End-Stage Liver Disease) score from three lab values — serum bilirubin, INR, and serum creatinine — using the standard logarithmic formula: MELD = 3.78×ln(bilirubin) + 11.2×ln(INR) + 9.57×ln(creatinine) + 6.43, with values floored at 1.0 to keep logarithms defined.

Hepatologists, transplant coordinators, and nurses use the MELD score to gauge the severity of chronic liver disease and, most notably, to prioritize patients on liver transplant waiting lists, since the score correlates strongly with 90-day mortality risk. Enter the three lab values to get the calculated MELD score.
