A model for end-stage liver disease score, or MELD score, is a number used to help determine a patient’s priority for receiving a liver transplant, explains the California Pacific Medical Center. There are four MELD levels, and a higher score indicates greater urgency.
The MELD score is a numerical value calculated from recent lab results that ranges from 6, indicating low urgency, to 40, the highest urgency, according to the California Pacific Medical Center. The MELD level determines how frequently the lab tests occur and go into the transplant database. Test frequency ranges from yearly, for scores equal to 10 or less, to every seven days, for scores of 25 or greater.
