Cockcroft and Gault formula (ml/min) |
For males: [(140—age) × actual BW]/sCr × 72 |
For females: ([(140—age) × actual BW]/sCr × 72) × 0.85 |
sCr in mg/dL |
The equation was calculated three times: |
(1) Using actual BW for all patients |
(2) Using actual BW for patients with BMI <30 kg/m2 and ideal BW for those with BMI >30 kg/m2 |
(3) Using actual BW for patients with BMI <30 kg/m2 and adjusted BW for those with BMI >30 kg/m2 |
Ideal BW |
Males: 50 kg + 2.3 kg for each inch above 60 inches of height |
Females: 45.5 kg + 2.3 kg for each inch above 60 inches of height |
Adjusted BW = ideal BW + [0.4 × (actual BW—ideal BW)] |

Modification of diet in renal disease study equations (ml/min/1.73 m2) |
Four-variable equation: 175 × sCr −1.154 × age−0.203 × 0.742 (if female) |
Six-variable equation: 170 × sCr−0.999 × (Age)−0.176 × (0.762 if patient is female) × (BUN)−0.170× (albumin)0.318 |
sCr in mg/dL, albumin in g/dL, BUN in mg/dL; to convert BUN from mmol/L to mg/dL, divide by 0.3571 |

Chronic kidney disease epidemiology collaboration (CKD-EPI) equations (ml/min/1.73 m2) |
For females with sCr ≤ 0.7: GFR = 144 × (sCr/0.7)−0.329 × (0.993)age |
For females with sCr > 0.7: GFR = 144 × (sCcr/0.7)−1.209 × (0.993)age |
For males with sCr ≤ 0.9: eGFR = 141 × (sCr/0.9)−0.411 × (0.993)age |
For males with sCr > 0.9: eGFR = 144 × (sCr/0.9)−1.209 × (0.993)age |
Age in years and sCr in mg/dL |

Jelliffe equation (ml/min/1.73 m2) |
For males: (98–16) × (age—20/20)/sCr |
For females: [(98–16) × (age—20/20)/sCr] × 0.9 |
Age in years and sCr in mg/dL |
