Cockcroft-Gault Equation

Males:

CrCl (mls/min) = [(140 - Age) × IBW (kg) × 1.23] / Sr. creat (μmol/L)

Females:

CrCl (mls/min) = [(140 - Age) × IBW (kg) × 1.04] / Sr. creat (μmol/L)

IBW = ideal body weight. In obese patients, use adjusted body weight (AdjBW). If BMI < 18.5 kg/m², use actual body weight.

Body Weight Calculations
AbbreviationTermHow to estimate (in kg)
ABWActual body weight-
IBWIdeal body weightMale: 50 + [0.91 × (height in cm - 152.4)]
Female: 45.5 + [0.91 × (height in cm - 152.4)]
AdjBWAdjusted body weightIBW + [0.4 × (ABW - IBW)]
Example: A 160kg man whose height is 170cm (BMI = 55.4 kg/m²). ABW = 160kg, IBW = 66kg and AdjBW = 103.6kg.
