OPTN Policy 9 Table 9-1 PELD-Cr from age, albumin, bilirubin, INR, creatinine or

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.
