Instructions
The MELD-Na score is a validated tool used to assess the severity of chronic liver disease and prioritize patients for liver transplantation. It is an update to the original MELD score, incorporating serum sodium alongside bilirubin, INR, and creatinine to better predict short-term mortality. To use this tool, input the patient’s laboratory values into the standardized formula. The resulting score provides a mortality estimate and helps guide transplant allocation decisions. This scoring system is required by UNOS/OPTN for liver transplant listing in many regions.
