Uses three laboratory values (albumin, bilirubin and INR), a presence of growth failure (<2 standard deviations below average height or weight), and an indicator of whether the patient is less than one year of age to calculate a score predictive of the risk of death within three months on the liver waiting list for candidates under the age of 18. The range of PELD scores is greater than that of MELD, ranging from less than zero to greater than 40.
