MELD 3.0 (Liver Disease Severity)
MELD 3.0 (Kim 2021): the current OPTN liver-allocation score, successor to MELD-Na, adding female sex and albumin.

Example
- Sex
- Female
- Serum bilirubin
- 4.0 mg/dL
- INR
- 2.0
- Serum creatinine
- 2.0 mg/dL
- Serum sodium
- 130 mEq/L
- Serum albumin
- 2.5 g/dL
Result: MELD 3.0 32/40 — very high waitlist priority.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Bounds
- Labs floored at 1.0; creatinine capped at 3.0 (dialysis sets it to 3.0); sodium 125-137; albumin 1.5-3.5; score bounded 6-40.
- >= 15
- Conventional transplant-benefit threshold; a higher score predicts higher 90-day waitlist mortality.
What you enter
- Sex (female adds 1.33 points)
- Serum bilirubin (mg/dL)
- INR
- Serum creatinine (mg/dL)
- Serum sodium (mEq/L)
- Serum albumin (g/dL)
- >= 2 dialysis sessions in prior week / 24h CVVHD (sets creatinine to 3.0)
How this is calculated
- Formula
- 1.33*(female) + 4.56*ln(bili) + 0.82*(137-Na) - 0.24*(137-Na)*ln(bili) + 9.09*ln(INR) + 11.14*ln(creat) + 1.85*(3.5-alb) - 1.83*(3.5-alb)*ln(creat) + 6.
