The Urea Reduction Percentage (URR) calculator helps assess the efficiency of hemodialysis treatment for patients with kidney failure. Understand how well toxins are removed from the blood with this essential medical tool.

Formula:

The Urea Reduction Percentage (URR) is calculated using the following formula:

URR = ((Pre-dialysis BUN - Post-dialysis BUN) / Pre-dialysis BUN) × 100%

Where:

  • Pre-dialysis BUN: Blood Urea Nitrogen level before dialysis (mg/dL)
  • Post-dialysis BUN: Blood Urea Nitrogen level after dialysis (mg/dL)
