nPCR Calculator

An indicator for assessing protein intake in dialysis patients
PCR (g/kg/day) = 0.22 + {(0.036 x [ID BUN (mg/dL)] x 24) / [interval (hr)]} + {([Urine urea (g)] x 150) / ([interval (hr)] x [weight (kg)])}

[ Fill in if the patient has urine output ]

Recommended to maintain nPCR ≥ 1.0–1.2 g/kg/day
nPCR ≤ 0.8 g/kg/day indicates malnutrition
