🫀 MELD-Na Score
Sodium-adjusted MELD (UNOS 2016) for end-stage liver disease severity and allocation reference. Instant, browser-side.
MELD-Na Score
Total bilirubin (µmol/L)
INR
Creatinine (µmol/L)
Sodium (mmol/L)
Dialysis ≥ 2× in the past week
When to use
Estimate 90-day mortality risk in chronic liver disease; allocation follows your own transplant system's standard.
How it works
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.
Key points
- 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.
