Formula: MELD = 3.78×ln(Bili) + 11.2×ln(INR) + 9.57×ln(Cr) + 6.43. MELD-Na = MELD + 1.32×(137-Na) - 0.033×MELD×(137-Na). Range 6 to 40 points.

In-Depth Guide & Mathematical Methodology

🧬 UNOS Transplant Priority Tiers

MELD-Na < 15: Low 90-day mortality (< 6%). Transplant benefit does not outweigh waitlist mortality.

MELD-Na 15 - 24: Moderate 90-day mortality (6-20%). Standard transplant listing priority.

MELD-Na ≥ 25: High 90-day mortality (> 50%). Urgent allocation priority.
