PCR — Protein Catabolic Rate in Dialysis

Calculate Protein Catabolic Rate (PCR) and normalized PCR (nPCR) in hemodialysis patients from interdialytic BUN change and urine urea excretion to assess protein intake and nutritional status.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate Protein Catabolic Rate (PCR) and normalized PCR (nPCR) in hemodialysis patients from interdialytic BUN change and urine urea excretion to assess protein intake and nutritional status

Each component has a specific meaning:

  • Interdialytic BUN change — The interdialytic bun change recorded for the scenario being assessed.
  • Urine urea excretion — The urine urea excretion recorded for the scenario being assessed.

Note: Interpret the pcr dialysis result against the thresholds and context described above.

How to Use

Enter the interdialytic BUN change, urine urea excretion for the scenario you are assessing. Calculate Protein Catabolic Rate (PCR) and normalized PCR (nPCR) in hemodialysis patients from interdialytic BUN change and urine urea excretion to assess protein intake and nutritional status. Use the pcr dialysis result to inform your calculation.
