How this service works
OPTN Policy 9 Table 9-1 PELD-Cr from age, albumin, bilirubin, INR, creatinine or dialysis/CVVHD, and caller-assigned minimum CDC height or weight Z-score. PELD = (sum of Table 9-1 terms + 1.5287) × 10 + 2.82; nearest integer; minimum 6. Albumin, bilirubin, and INR floor at 1.0; creatinine 1.3 mg/dL if >1.3 or dialysis/CVVHD. Not a transplant listing order. magent does not compute CDC LMS Z from height or weight.
Output
Returns the PELD-Cr integer score computed per OPTN Policy 9 Table 9-1, applying policy floors (albumin, bilirubin, INR floored at 1.0; creatinine capped at 1.3 mg/dL if elevated or on dialysis/CVVHD), with a minimum reported score of 6. Does not return a transplant listing order.
Example use cases
Infant liver failure PELD scoring
“What's the PELD-Cr score for a 0.8-year-old infant with albumin 1.5 g/dL, bilirubin 12 mg/dL, INR 2.5, creatinine 0.3 mg/dL, not on dialysis, and a minimum CDC Z-score of -3.2?”
Child on dialysis with biliary atresia
“Compute the PELD-Cr for a 5-year-old on dialysis twice last week, with albumin 18 g/L, bilirubin 340 µmol/L, INR 3.1, and a minimum CDC height or weight Z-score of -2.8.”
Serial PELD monitoring for transplant candidate
“My 9-year-old patient's latest labs are albumin 2.8 g/dL, bilirubin 4.2 mg/dL, INR 1.6, creatinine 1.1 mg/dL, not on dialysis, and CDC Z-score minimum is -1.9 — what is the current PELD-Cr score?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/peld_crWhen to prefer
Use this endpoint when you need a standards-compliant PELD-Cr score per OPTN Policy 9 Table 9-1 for a pediatric candidate under age 12, especially when you already have the CDC LMS Z-score pre-calculated and need precise policy-conformant flooring and knot logic applied automatically. Prefer it over manual computation to ensure exact policy compliance including creatinine capping, albumin/bilirubin/INR floors, and age-band clamping.
Side effects
- Missing required parameters (age_years, inr, dialysis_or_cvvhd, min_cdc_z) returns validation error
- Age outside 0–12 range is out of scope for PELD-Cr
- Providing both albumin_g_dl and albumin_g_l simultaneously causes an error
- Providing both bilirubin units or both creatinine units simultaneously causes an error
- Payment failure or missing x402 payment header returns 402 status
- min_cdc_z not pre-computed by caller — magent does not derive Z from raw height/weight measurements
