Laboratory Values

mmol/L (for MELD-Na)
Formula (MELD-Na)
MELD = 3.78×ln(bilirubin mg/dL) + 11.2×ln(INR) + 9.57×ln(creatinine mg/dL) + 6.43
MELD-Na = MELD + 1.32×(137−Na) − 0.033×MELD×(137−Na)
(applied when Na 125–136 mmol/L)
Range: 6–40 (capped)
MELD-Na = MELD + 1.32×(137−Na) − 0.033×MELD×(137−Na)
(applied when Na 125–136 mmol/L)
