Estimate the original creatinine / bilirubin / INR MELD score, floored at 6.
| MELD | – |
Use this calculator for the original (pre–MELD-Na) formula: 9.57 × ln(creatinine) + 3.78 × ln(bilirubin) + 11.2 × ln(INR) + 6.43. Each lab is floored at 1; creatinine is also capped at 4 mg/dl. The result is rounded and not shown below 6. Dialysis and sodium are extra UNOS rules not in this sketch. This is not a listing decision.
Bilirubin: Total bilirubin, in mg/dl.
INR: International normalised ratio.
Creatinine: Serum creatinine, in mg/dl. On dialysis UNOS would set this to 4.
MELD: Original MELD integer.
