• Model for End-Stage Liver Disease (MELD): Used to estimate the survival probability of a patient with end-stage liver disease. The model uses the most recent laboratory tests for serum bilirubin, international normalized ratio (INR), and serum creatinine to generate a "MELD score". The MELD scores range from 6 (less ill) to 40 (gravely ill) and are often used to prioritize patients waiting for a liver transplant.
