IN 30 SECONDS
A MELD score is a number from your blood work that tells the transplant system how urgently you need a liver. It is updated each time your labs are drawn. A higher number generally means greater urgency. A lower number generally means more time.
MELD is one of several things your team is watching. It does not capture symptoms, quality of life, or how you will do after transplant. The number is information for the people taking care of you, not a verdict on you.
This article explains what the number measures, how it is used to decide who is offered an organ first, what it does not measure, and what to ask your team. If you do not know your current MELD, you can calculate it from your blood work at nationalfriends.org.
If you have just been told you have a MELD score, or if you have one and no one has fully explained it, you are in the right place. You do not have to read the whole article. The first few sections will give you what you need. The rest is there when you are ready.
If you are the spouse, parent, child, or close friend of someone with a MELD score, this article is also for you. You are doing the work of love at a hard time, and the questions and information here apply to you too.

This article explains what the number is, what it measures, what it is used for, and what it does not tell you. It is not a substitute for the conversation with your transplant team. Clinical decisions belong to them and to you, together. The goal here is for you to walk into that conversation knowing what you are being told.
If you do not know your current MELD score but you have your recent bloodwork, you can calculate it yourself using our calculator at nationalfriends.org. Same numbers your team uses, same formula, no login.
The Short Version
A MELD score is a number, calculated from a few blood test values, that estimates how sick a person is from advanced liver disease. When a donor liver becomes available, the system uses MELD to help decide who is offered it first. A higher number generally means greater medical urgency. A lower number generally means more time.
That is the core. If that is all you need right now, you have it. The rest of this article fills in the picture.
What MELD Stands for, and What it Measures
MELD stands for Model for End-Stage Liver Disease. The current version is called MELD 3.0, and it became the standard for adult liver transplant candidates on July 13, 2023. It is built from six pieces of information, all drawn from blood tests and your medical record.
Bilirubin, a yellow substance the liver normally clears from your blood. When the liver is struggling, bilirubin builds up.
INR (International Normalized Ratio), a measure of how long it takes your blood to clot. The liver produces the proteins responsible for clotting, so a higher INR can signal the liver is not keeping up.
Creatinine, a measure of how well your kidneys are working. Kidney problems often accompany advanced liver disease.
Sodium, a basic electrolyte in your blood. Lower-than-normal sodium can be a sign of more advanced liver disease.
Albumin, a protein the liver makes. Lower albumin can reflect declining liver function.
Sex, included to correct a problem with the older formula. Creatinine levels are affected by muscle mass, and because women on average have less muscle mass than men, the older formula tended to understate how sick women were. Women waited longer and died on the list more often than men with the same true level of illness. MELD 3.0 corrects for this.
If you have been on the list for a while, your score has been calculated several different ways over your years on it. The 2001 original used only bilirubin, INR, and creatinine. A 2016 update added sodium (MELD-Na). MELD 3.0 added albumin and the sex adjustment in 2023. The system you are in now is more accurate than the one most patients were originally listed under.
What Your Number Means
Most patient guides will tell you MELD runs from 6 to 40, and that is true for how the allocation system uses the score. The system that decides who is offered an organ first treats 40 as the top of the scale. Patients at 40 or above are all considered the highest priority, with ties broken by waiting time and other factors.
But the underlying math of MELD 3.0 can produce scores higher than 40. Patients with calculated scores of 45, 50, or higher exist, and their teams know it. There is active discussion in the transplant community about removing the cap. If your team has told you your MELD is above 40, that is real. It is not a typo. The allocation system will treat you the same as anyone else at 40 for priority purposes, but your team is paying close attention.
It is tempting to read a MELD score as a verdict. A higher number feels worse than a lower number, and to some degree that is what the score is saying. MELD was originally developed to estimate short-term mortality risk in patients with advanced liver disease, and that is what the math does. So the number is, honestly, related to how sick you are.
But what MELD really is, in the system as it operates today, is a tool for prioritizing organ offers. A patient with a MELD of 30 will be offered an available organ before a patient with a MELD of 18, all other things being equal, because the system gives the next liver to the patient who needs it most urgently. The MELD score is a place in a queue more than a sentence.
Two patients with the same MELD score are not in the same medical situation. Two patients with very different MELDs can both end up doing well after transplant. The score captures one important thing: the lab snapshot of your liver function on a given day.
MELD captures one important thing about you. It does not capture everything about you.
How MELD is Used
MELD shows up in your time on the waiting list in four ways.
First, allocation. When a donor liver becomes available, the OPTN allocation system uses MELD scores, along with blood type, body size, geography, and other factors, to decide which patient is offered the liver first. The “acuity circles” framework prioritizes the sickest patients within a defined distance of the donor hospital.
Second, listing decisions. Some transplant programs use MELD as part of deciding when to list a patient, when to move a patient between active and inactive status, or when to reconsider transplant. These thresholds vary significantly by program, and where you are listed matters more than most patients realize. We have a separate article on this called You can be evaluated at more than one center. It is worth your time.
Third, monitoring. Your team will recalculate your MELD periodically as your lab values change. Sometimes that means weekly, sometimes monthly. The score moves with your labs.
Fourth, exception points. These are extra points added to a patient’s standard MELD score in situations where the lab calculation does not fully reflect urgency. The most common reason is liver cancer (hepatocellular carcinoma). Exception point requests are reviewed by the National Liver Review Board. If your team has discussed exception points with you, they will explain what that means for your specific situation.
Why Your MELD Changes
Your MELD score is not a fixed thing. It is recalculated every time your lab values are drawn. If your bilirubin goes up, your MELD might go up. If your kidney function improves, your MELD might come down. If a medication changes your INR, your MELD shifts accordingly.
This means two things.
First, your MELD will move during your time on the list. A score that goes up by a few points does not necessarily mean a crisis. It may mean that one lab value drifted higher this week than last week.
Second, the MELD on any given day is a snapshot, not a trend. What matters more than today’s number is the pattern your team is watching over weeks and months.
If you find yourself checking your MELD score the way some people check the markets, take a step back. The score is information for your team. They are watching it in context, alongside how you look, how you feel, what your imaging shows, what your other labs say, and what your overall trajectory has been. Your job is to tell them what is happening in your body and your life. Their job is to put the number in context.
What MELD Does Not Measure
MELD is a useful tool. It is also a narrow one. It is worth knowing plainly what is not in the number.
MELD does not measure your quality of life. Two patients with the same MELD can have very different days.
MELD does not measure your symptoms. Ascites (fluid in the abdomen), hepatic encephalopathy (confusion related to liver disease), fatigue, itching, pain, weight loss, sleep disturbance: none of these directly factor into the calculation. They matter enormously to you and to your team. They are just not what the score is built to measure. This is one of the reasons your team will ask you how you are feeling at every appointment. The questions are not small talk. They are filling in what the labs do not capture.
MELD does not measure which liver disease you have. A patient with MASLD-related cirrhosis and a patient with autoimmune hepatitis can have the same MELD. The diseases behave differently. The score does not distinguish.
MELD does not measure how you will do after transplant. That depends on many things: your overall health, your support system, the donor organ, the surgery itself, how your body responds to the new liver, how well you tolerate immunosuppression.
The MELD score is about the wait, not the outcome.
How to Talk to Your Team About Your MELD
If you remember nothing else from this article, take this. Your MELD score is a number on a chart. The conversation about your MELD is a conversation with the people who know your case. The Foundation is not the source of clinical decisions about you. Your transplant team is.
Questions that can be useful to bring to an appointment:
• What is my current MELD, and what was it last time?
• Has anything in my labs changed recently in a way I should know about?
• What is the median MELD at transplant at this program, and how does my score compare?
• Are there reasons we are considering an exception point request for my situation?
• Are there symptoms or changes in my function that you would want to know about, even if my labs look stable?
• Is there anything I can do, on my end, that affects what my MELD is doing?
None of these have universal answers. Your team has them for you. What you bring to the appointment is your willingness to ask.
If you are a caregiver reading this on behalf of someone you love, the same questions are yours to ask. You are often the person tracking what changed, what got harder, what the patient is too tired to put into words. Bring your own list. Bring a notebook. Write down what the team says. The patient will not remember half of it after the appointment is over, and that is normal. The notes are for both of you, later.
If you or someone you love is newly diagnosed and trying to figure out where to be evaluated, our guide Finding a transplant center that fits you walks through the questions, the data, and the considerations that matter. If you are considering being listed at more than one program, The Dual Listing Guide covers what is involved.
WHAT THIS MEANS FOR YOU
Your MELD score is one of the most important numbers in your transplant journey, and it is also just one number among many that your team is watching. It is not a prediction of what will happen to you. It is a snapshot in time, based on your lab values, used by the system to help decide who is offered an organ first.
The score determines a great deal. It does not determine everything. Your symptoms, your daily life, your trajectory over weeks and months, where you are listed, whether your team is hearing about the parts of your illness the labs do not capture: all of these matter alongside the number.
You now understand what the number is and how it is used. That is a real thing. You walked into this article without it and you are walking out with it.
When you are ready, there is more to know.
