MELD-Na Transplant Score
Enter creatinine, bilirubin, INR, and sodium to reproduce the historical 2016 MELD-Na calculation.
Use the MELD-Na Transplant Score
Lab Values
Enter the patient's most recent lab results.
Capped at 4.0 per UNOS. Dialysis patients: enter 4.0.
Values outside 125–137 are clamped per UNOS formula.
Historical Score Severity Reference
| MELD-Na | Historical severity band | 90-Day Mortality |
|---|---|---|
| < 10 | Lower historical score | < 2% |
| 10–14 | Mild historical band | 2–6% |
| 15–19 | Moderate historical band | 6–20% |
| 20–24 | Serious historical band | 20–30% |
| 25–34 | High historical band | 30–50% |
| ≥ 35 | Very high historical band | > 50% |
These broad mortality bands are historical approximations, not current OPTN allocation thresholds or an individual prognosis. Current score and offer priority must be obtained from the transplant program.
Summary
Enter creatinine, bilirubin, INR, and sodium to reproduce the historical 2016 MELD-Na calculation.
How it works
- Enter serum creatinine (mg/dL) — values below 1.0 are set to 1.0; above 4.0 are capped at 4.0 per UNOS rules.
- Enter total serum bilirubin (mg/dL) from the most recent lab draw.
- Enter the INR (international normalized ratio) — the coagulation component of the formula.
- Enter serum sodium (mEq/L) — clamped to 125–137 per UNOS MELD-Na policy.
- Click Calculate to apply the former 2016 OPTN MELD-Na formula.
- Review the historical score and formula breakdown; do not interpret it as current allocation priority.
Use cases
- Reproduce a MELD-Na value recorded before the July 2023 policy change.
- Compare historical cohorts that reported the former MELD-Na score.
- Monitor disease progression in cirrhosis patients over serial lab draws.
- Study how sodium affected the former allocation calculation.
- Support hepatology clinic consultations and patient education on transplant urgency.
- Evaluate when to refer a patient to a transplant center based on score trajectory.
- Compare lab-to-lab score changes to understand how quickly disease is progressing.
