Equations to Estimate GFR

Estimate GFR using Cockcroft and Gault

CLCr = ((140-age) * weight (kg) * 0.85[female])/(SCr(mg/dl) * 72)
= (140-72) * 59 * 0.85/1 * 72
= 68 * 59 * 0.0118
= 47.36ml/min
G3a
Estimate GFR using Cockcroft and Gault

CLCr = ((140-age) * weight (kg) * 0.85[female])/(SCr(mg/dl) * 72)
= (140-65) * 89 * (1/(2.6 * 72))
= 75 * 89 * 0.00534
= 35.66ml/min
G3b
Estimate GFR using Cockcroft and Gault

40.6ml/min
Estimate GFR using Cockcroft and Gault

CLCr = ((140-age) * weight (kg) * 0.85[female])/(SCr(mg/dl) * 72)
= ((140-45) * 104 * 1/(3.0 * 72))
= 95 * 104 * 1/216
= 45.7ml/min G3a
