Anyone with a serious liver disease should understand what a MELD score is and how doctors arrive at this important number. If you are a candidate for a liver transplant, a MELD score helps determine how urgently you need a transplant.
The MELD score estimates a patient’s chances of surviving their disease during the next three months. Organ allocation is determined by the Organ Procurement and Transplantation Network (OPTN). Livers from deceased donors are allocated to the sickest patients first.
The MELD score ranges from six to 40 and is based on results from several lab tests. The higher the number, the more likely you are to receive a liver from a deceased donor when an organ becomes available.
Your MELD score is a prime indicator in determining how urgently you need a transplant. But, it isn't the only factor. Other considerations include:
While patients with a MELD score less than 15 are often not listed for a liver transplant because their chance of receiving a liver through traditional allocation is so low, a living-donor liver transplant offers a life-saving option and the opportunity to receive a transplant sooner. By exploring a living donor transplant, patients with a low MELD score can still be considered for a liver transplant.
Patients with a low MELD score should still be considered for a liver transplant since a significant number of patients are much sicker than what their MELD score can represent. Living-donor liver transplant can be a life-saving option to this subset of patients who otherwise cannot get a deceased donor liver transplant with the UNOS MELD score allocation.
Your MELD score is based on results from four blood tests that, together, show how well your body is functioning. You will be tested for:
Your MELD score changes as your condition changes. If you get sicker, your score goes up.
Depending on how critical your disease is, your MELD score may be recalculated as often as once a week.
Doctors look at your last MELD score to determine when to order new lab tests.
Here are typical MELD scores and how often they're recalculated:
Since your MELD score is calculated by your doctor, you're not responsible for updating it. It's up to your doctor to decide when you need new tests.
Make sure you attend all follow-up appointments and complete all necessary lab tests — and check in with your doctor anytime your condition worsens. You should call your transplant coordinator if you have questions about your MELD score.
