The MELD score is a numerical scale ranging from 6 to 40, with higher scores indicating more severe liver dysfunction and a higher risk of mortality.

It is calculated using serum bilirubin, serum creatinine, and the international normalized ratio (INR) for prothrombin time.

The MELD score is widely used to prioritize patients for liver transplantation and to assess the urgency of transplant needs.
