A plain-language guide for patients and caregivers
Key Takeaway: Your MELD score helps determine your place on the transplant waiting list. Higher scores mean more urgent need. This guide explains what MELD means and how it affects your transplant journey.
MELD stands for Model for End-Stage Liver Disease. It's a scoring system developed by medical experts to predict how urgently someone needs a liver transplant. The score ranges from 6 to 40:
The MELD system replaced older methods in 2002 to make organ allocation more fair and based on medical need rather than waiting time alone.
Your MELD score is calculated from three blood tests:
Measures how well your liver processes waste. High levels suggest liver dysfunction.
Measures kidney function. Liver disease can affect kidneys, so this matters for transplant outcomes.
Measures blood clotting time. Liver makes clotting factors, so INR shows liver function.
A mathematical formula combines these values to produce your MELD score. You don't need to calculate it yourself — your transplant team will tell you your score.
Note: There are exceptions and special cases (like MELD-Na which includes sodium levels). Your team will use the appropriate version for your situation.
This is one of the most common questions patients ask. Here's what you need to understand:

MELD (Model for End-Stage Liver Disease) is a scoring system that estimates how severe your liver disease is. It ranges from 6 to 40, with higher scores meaning more urgent need for transplant.
MELD score is calculated using three blood test results: bilirubin (liver function), creatinine (kidney function), and INR (blood clotting). The formula produces a number between 6 and 40.
There's no "good" MELD score — higher scores mean you're sicker and get priority, but also mean more urgent illness. Scores above 15 typically qualify for transplant listing. Your transplant team will explain what your specific score means.
MELD scores are recalculated regularly based on your blood tests. How often depends on your score range — those with higher scores are updated more frequently to ensure the sickest patients maintain priority.
