MELD/PELD Calculators (Liver)²¹ 

The MELD/PELD Calculator, developed by the UNOS Liver and Intestinal Organ Transplantation Committee, is a utility that allows you to enter hypothetical or actual parameters for a potential liver transplant recipient to calculate their MELD or PELD score.

The MELD/PELD Calculator provided on this site uses the specific formulas approved by the OPTN/UNOS Board of Directors and used for the allocation of livers by the OPTN match system.

The MELD score calculation uses: Serum Creatinine (mg/dL)** Bilirubin (mg/dL) INR **For patients who have had dialysis twice within the last week, the creatinine value will be automatically set to 4 mg/dL. The MELD Calculator is used for patients who are 12 years and older. After entering the laboratory values, you may calculate the score by clicking Calculate. The MELD score displays in the MELD Score field. You can also calculate a score by simply tabbing into the MELD Score field. Click here to access the MELD Calculator

The PELD score calculation uses: Albumin (g/dl) Bilirubin (mg/dL) INR Growth failure (based on gender, height and weight) Age at listing The PELD Calculator is used for patients who are under 12 years old. After entering the laboratory values, you may calculate the score by clicking Calculate. The PELD score displays in the PELD Lab Value field. You can also calculate a score by simply tabbing into the PELD Lab Value field. Click here to access the PELD Calculator
