AI Summary The MELD score is calculated from bilirubin, creatinine, and INR blood tests; a score of 6 to 9 reflects low short-term risk and a score of 40 or more reflects critical risk, and because it is the main driver of liver transplant waiting-list priority, your team rechecks it regularly.
Medically reviewed.
Once your transplant team lists you, your place is not a fixed line. It shifts with your MELD score, a number from 6 to 40 that is calculated from your bilirubin, creatinine, and INR blood tests. A higher score means more severe liver disease and greater urgency. Your team repeats these tests regularly, so your score, and your place on the list, can change over time.
When a deceased-donor liver becomes available, it is offered based on blood type compatibility, body and liver size, geography, and how long a candidate has waited. A living donor can also shorten the wait for some people.

Waiting list basics
Once you are added to the national liver transplant waiting list, your priority for a donor liver is based mainly on your MELD score (Model for End-Stage Liver Disease). MELD uses three blood test results — bilirubin, creatinine, and INR — to estimate how sick your liver has become and how urgently you need a transplant. Your transplant team rechecks your MELD score regularly with new blood draws. The score can move up or down, and a higher score generally moves you higher on the list because it reflects greater short-term risk. The ranges below relate to 90-day risk without a transplant.
| MELD Score | Risk Level | What It Means |
|---|---|---|
| 6–9 | Low risk | Liver function is relatively preserved, with low short-term risk of complications. |
| 10–19 | Moderate risk | Some liver dysfunction is present, with increased risk of complications and closer monitoring. |
| 20–29 | High risk | Significant liver dysfunction with a high risk of complications; urgent transplant evaluation may be needed. |
| 30–39 | Very high risk | Severe liver disease with very high risk; the patient is likely an urgent transplant candidate. |
| 40+ | Critical | Extremely high risk of death without immediate intervention. |
Donor matching
Glossary
These terms come up often once you're listed. Knowing them helps you follow updates from your transplant coordinator.
What you can influence
Some factors are within your control, and taking action on them can shorten your time on the list.
If a healthy adult in your life is willing and eligible, a living donor liver transplant lets you receive part of a liver without waiting for a deceased-donor offer. Having a potential living donor is linked to receiving a transplant earlier in the disease course.
If your condition includes a factor the MELD formula does not fully capture, such as certain liver tumors, your team can apply for exception points. Gathering imaging and doctor's letters ahead of each review helps your case stay current.
Working with your dietitian and physical therapist to hold a stable, healthy weight keeps you in the size-matching window that lets more donor livers be considered a fit.
Attend every scheduled lab draw and appointment. Fresh labs keep your MELD score accurate, and missed appointments can delay your case being seen at the next review.
While you wait
Life on the waiting list has a rhythm. These habits keep you medically ready and easier to reach.
Being on the list is active readiness, not passive waiting. Tending to your health, your logistics, and your emotions all help you meet the call prepared.
The call
The call usually comes with little warning. Most patients receive about 6 to 10 hours of notice before they need to arrive at the hospital. Answer, listen carefully, and confirm where to go and any instructions.
Grab your packed bag, ID, and any paperwork your team asked for. Confirm your ride or transport plan; if you live far away, use the shuttle or travel plan you arranged in advance.
Follow any instructions about eating or drinking before surgery, wear loose comfortable clothing, and keep a list of key contacts visible in your bag so your team can update whoever needs to know.
A transplant can still be cancelled after you arrive — for example, if the donor liver is not healthy enough for transplant, or if a new medical issue makes surgery too risky. If this happens, you may need more testing before being offered a match again.
Coping with the wait
Emotions during the wait can swing between hope and disappointment. That response is normal, and it does not mean something is wrong with your case.
common questions
Your MELD score is the main driver of your priority. It is calculated from three blood tests: bilirubin, creatinine, and INR. A higher score means greater short-term risk, and donated livers usually go first to the people who are sickest. Your team redraws your labs regularly, so your score and your place on the list can change over time. If your condition is not fully captured by the formula, your team may also request exception points.
No. MELD sets priority, but a donor liver must also be a good fit for you. Blood type compatibility and body and liver size matching both matter. Where you live, your transplant center's donor service area, and how long you have been listed also play a part, along with any approved exception points. Blood type and the number of donors in your region can also change how long the wait takes.
Yes, it can. In a living donor liver transplant, a healthy person donates part of their liver to you, so you do not have to wait for a deceased-donor offer. Having a potential living donor is linked to receiving a transplant earlier in the disease course. The donor must be a suitable match and must be evaluated and approved first. Ask your transplant team how to start that conversation.
Exception points are extra priority added when a condition is not fully captured by the MELD formula. Examples include certain small liver tumors and severe itching from bile blockage. Your team applies on your behalf, and a transplant committee reviews the case. If you receive exception points, reviews come around every few months. Gather new imaging reports and doctor's letters ahead of each review so your case stays current, and ask your coordinator when the next one is.
Most patients receive about 6 to 10 hours of notice before they need to arrive at the hospital. A donor liver can become available at any time, day or night. Keep your phone charged and within reach, keep a packed bag ready, and plan your ride or travel in advance. Tell your transplant coordinator right away if your phone number, address, or travel plans change, since they can only call you if they can reach you.
Yes. The donor liver may turn out not to be healthy enough for transplant, or a new medical problem may make surgery too risky for you. If that happens, you may need more testing before you are approved for another match. Staying in close contact with your transplant team and keeping your health as stable as possible helps you be ready for the next offer.
It varies widely. For a deceased-donor liver, the wait can range from less than 30 days to more than 5 years. Your own timeline depends on your MELD score, blood type, body size, and how many donors are available in your region. A living donor can shorten it for some people. Your transplant team can explain what to expect in your situation.
