MELD Score Calculator: Assessing Liver Disease Severity

The MELD (Model for End-Stage Liver Disease) score is used worldwide to prioritise liver transplant waiting lists and to assess short-term mortality risk in people with cirrhosis and acute liver failure. This calculator uses the MELD-Na version, which includes sodium for improved predictive accuracy.

What MELD Measures

MELD combines three routine lab values — bilirubin, INR, and creatinine — that collectively reflect how severely the liver and kidneys are failing:

  • Bilirubin: A waste product the liver processes — elevated levels indicate liver dysfunction.
  • INR: A measure of blood clotting — the liver makes clotting factors, so a high INR indicates poor liver synthetic function.
  • Creatinine: Reflects kidney function — advanced liver disease often impairs kidney function (hepatorenal syndrome).
  • Sodium: Hyponatremia (low sodium) is common in advanced cirrhosis and worsens prognosis.

MELD Score and Mortality Risk

MELD Score3-Month Mortality (approximate)
Below 10<5%
10–19~10–20%
20–29~25–50%
30–39~50–70%
40+>70%

Clinical Use

  • Organ allocation: Patients with higher MELD scores receive higher transplant priority.
  • Prognosis discussion: Guides conversations about treatment options, palliation, and goals of care.
  • Monitoring: Trend in MELD over time (stable, improving, or worsening) guides management intensity.

Final Thoughts

The MELD score translates complex liver disease severity into a single actionable number used by hepatologists and transplant centers worldwide.
