Common questions
What is MELD-Na Score?
Sodium-adjusted MELD (UNOS 2016) for end-stage liver disease severity and allocation reference. Instant, browser-side.
How is MELD-Na Score calculated? What is the core formula?
MELD = 3.78·ln(bilirubin) + 11.2·ln(INR) + 9.57·ln(creatinine) + 6.43 (each floored at 1.0, creatinine capped 4.0); MELD-Na adjusts for sodium (125–137) when MELD > 11. Range 6–40.
When is MELD-Na Score used?
Estimate 90-day mortality risk in chronic liver disease; allocation follows your own transplant system's standard.
What are the key clinical points for MELD-Na Score?
Each component is floored at 1.0; creatinine is capped at 4.0. Dialysis ≥ 2× in the week sets creatinine to 4.0. Hyponatraemia raises the score. The score is bounded between 6 and 40.
