How this service works
McDiarmid 2002 PELD from bilirubin, INR, albumin, age under 1 year, and growth failure. Deterministic published listing arithmetic with citation; not a transplant listing recommendation.
Output
Returns the numeric PELD score computed from the McDiarmid 2002 formula, along with the formula citation and intermediate calculation values. Does not provide transplant listing recommendations.
Example use cases
Pediatric liver patient severity assessment
“I need the PELD score for a 4-year-old with total bilirubin 12 mg/dL, INR 2.1, albumin 2.8 g/dL, and no growth failure — can you run that for me?”
Infant PELD with SI unit labs
“Calculate PELD for an 8-month-old who has bilirubin 95 µmol/L, INR 1.7, albumin 22 g/L, and growth failure documented by the team.”
Borderline INR floor edge case
“What's the PELD score for a 3-year-old child with bilirubin 3.5 mg/dL, INR 0.9, albumin 3.1 g/dL, and no growth failure? I want to make sure the formula handles the INR floor correctly.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/peldWhen to prefer
Use this endpoint when you need to deterministically compute the PELD score for a pediatric patient (under 12 years old) using the published McDiarmid 2002 formula. Prefer this over MELD calculators when the patient is a child. Choose this when you need a citable, formula-exact result rather than a clinical recommendation.
Side effects
- Missing required parameters (age_years, inr, growth_failure) returns a validation error
- Providing both bilirubin_mg_dl and bilirubin_umol_l simultaneously returns an error
- Providing both albumin_g_dl and albumin_g_l simultaneously returns an error
- Age outside 0–11 years (PELD is only for children under 12) may return an out-of-range error
- INR or bilirubin values at extreme ranges may be floored per formula rules without warning
