PELD Score — Pediatric End-Stage Liver Disease

Calculates the Pediatric End-Stage Liver Disease (PELD) score for patients aged ≤ 11 years. Used by UNOS/OPTN to prioritize pediatric liver transplant waitlist allocation. The PELD score uses serum albumin, bilirubin, INR, growth failure status, and age < 1 year as parameters. Higher PELD score = higher 3-month mortality on waitlist = higher transplant priority. Patients ≥ 12 years use the MELD score system instead.
