Formula & Mathematical Methodology: eGFR Kidney Reference Equation

CrClCockcroftGault = ((140 − age) × weightkg) / (72 × creatininemgdL)
CrCl_CockcroftGault = ((140 − age) × weight_kg) / (72 × creatinine_mg_dL)
  • creatinineMgDl: Creatinine Mg Dl (mg/dL)
  • age: Age (years)
  • weightKg: Weight Kg (kg)

Rounding: Intermediate calculations retain full IEEE-754 floating-point precision; displayed clinical and fitness metrics round to 1 or 2 decimal places.

Worked Example: Benchmark Scenario: eGFR Kidney

Evaluate 2021 CKD-EPI eGFR (mL/min/1.73m²) and Cockcroft-Gault CrCl (mL/min).

  1. Enter your current anthropometric, laboratory, or training measurements in the units indicated.
  2. Substitute the values into the reference formula: CrCl_CockcroftGault = ((140 − age) × weight_kg) / (72 × creatinine_mg_dL).
  3. Compare the primary output and supporting thresholds across all three custom SVG charts.
Result: Evaluates eGFR Kidney using CrCl_CockcroftGault = ((140 − age) × weight_kg) / (72 × creatinine_mg_dL).

Frequently Asked Questions

How is the eGFR Kidney Function Calculator (2021 CKD-EPI Race-Free) calculated?
