🩺 Normalized Protein Catabolic Rate (nPCR)

UseWhen to use: HD nutrition adequacy review with pre-dialysis BUN and known spKt/V.

StrataLow nPCR suggests low intake or measurement issues; high values may reflect catabolism.

LimitsWhen not to use: other schedules / high KRU without adjusted equation. · Pitfall: BUN unit mismatch. · Not a sole diet Rx.

When to use

When to use: HD nutrition adequacy review with pre-dialysis BUN and known spKt/V.

How it works

nPCR ≈ BUN/(36.3 + 5.48×spKt/V + 53.5/spKt/V) + 0.168.

Key points

  • Depner-style thrice-weekly form.
  • g/kg/day.
  • Next: dietary recall / KRU.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Frequently asked questions

Does Normalized Protein Catabolic Rate (nPCR) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Normalized Protein Catabolic Rate (nPCR) calculated in practice? Can you show a worked example?
Inputs: Pre-dialysis BUN 60 mg/dL, spKt/V 1.4 → Result: nPCR 0.90 g/kg/day（Denominator: 82.2, Cue: ≈0.8–1.4 — common HD teaching band）
