interpretation: {"text":"MELD scores between 6-10 indicate a lower risk of mortality and may not require immediate transplantation.","label":"Low Risk"}; {"text":"MELD scores above 20 suggest a high risk of mortality and urgent need for transplantation.","label":"High Risk"}

The MELD score is a numerical scale ranging from 6 to 40, calculated using the patient's serum bilirubin, serum creatinine, and the international normalized ratio (INR) of prothrombin time. It is a critical tool in evaluating the severity of liver dysfunction.

A higher MELD score indicates more severe liver dysfunction and a greater risk of mortality. Scores above 20 generally signify a high priority for liver transplantation due to the increased risk of death without a transplant.

The MELD score is dynamic and can change over time as the patient's condition improves or worsens. Regular monitoring is essential to reassess the need for transplantation and to manage care effectively.

Frequently asked questions

A normal MELD score is typically between 6 and 10, indicating less severe liver disease.
How often should MELD scores be checked?
MELD scores should be checked regularly, especially in patients with worsening liver function, to monitor disease progression and transplant needs.
