PELD (Pediatric End-Stage Liver Disease) Score Calculator
This calculator is designed to help healthcare professionals calculate the PELD score for pediatric patients under 12 years old with end-stage liver disease. It uses specific laboratory values and clinical criteria to determine the severity of liver disease, assisting in prioritization for liver transplantation.
Calculate PELD Score

Data Source and Methodology
All calculations are based on the formulas and data provided by the Pediatric Liver Transplantation Study Group. Visit MDCalc for more information.
The Formula Explained
PELD = 0.48 * ln(serum bilirubin) + 1.857 * ln(INR) - 0.687 * ln(serum albumin) + 0.436 * (if age <1 year) + 0.667 * (if growth failure is present)
Glossary of Terms
- Serum Bilirubin: A substance produced by the breakdown of red blood cells.
- Serum Albumin: A protein in the blood that helps maintain blood volume.
- INR: A measure of blood clotting.
How It Works: A Step-by-Step Example
For a patient with a bilirubin of 3 mg/dL, albumin of 2.5 g/dL, INR of 1.5, aged 6 months with growth failure, the PELD score is calculated as follows: PELD = 0.48 * ln(3) + 1.857 * ln(1.5) - 0.687 * ln(2.5) + 0.436 + 0.667.
Frequently Asked Questions (FAQ)
What is the PELD score used for?
The PELD score is used to assess the severity of liver disease in children under 12 years old and prioritize them for liver transplantation.
What is considered a normal PELD score?
A lower PELD score indicates less severe liver disease, while a higher score indicates more severe disease.
Can the PELD score change over time?
Yes, the PELD score can change as the patient's lab values and clinical status change.
Is the PELD score applicable for adults?
No, the PELD score is specifically for pediatric patients. The MELD score is used for adults.
Why is growth failure considered in the PELD score?
Growth failure is a significant factor in pediatric liver disease, affecting the overall severity and urgency for transplantation.
