In obesity, actual body weight should be used in the calculation of CrCl via the Cockcroft-Gault method to obtain more reliable measures of renal function. 2 However, it is worth noting that the original formula was only tested in a non-obese patient population. 1
The MDRD formula underestimates the CrCl in rugby players, even when corrected for BSA. Conversely, the CG formula more closely approximates the actual CrCl measurement. The equations to estimate GFR should be used with caution in subjects having atypical anthropometric characteristics.
Kreatinin Clearance (CCr) Cockcroft-GaultCURB-65 Pneumoni Severity Score Diagnostiska kriterier för Kawasaki sjukdom. Diagnostisk regel The original Cockcroft-Gault equation, derived in 1976, relied on non-standardized creatinine measurements. With the use of internationally standardized creatinine measurements, the equation significantly overestimates the GFR (10-40%). Because it includes weight in the equation, the output of the CG equation is in ml/min (compare to MDRD or CKD-EPI, with output units of ml/min/1.73m2). The Cockcroft and Gault formula (1973) C Cr ={((l 40–age) x weight)/(72xS Cr)}x 0.85 (if female) Abbreviations/ Units. C Cr (creatinine clearance) = mL/minute. Age = years.
Cockcroft and Gault equation: CrCl = [ (140 - age) x IBW] / (Scr x 72) (x 0.85 for females) Note: if the ABW (actual body weight) is less than the IBW use the. actual body weight for calculating the CRCL. Estimate Ideal body weight in (kg) Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet. The Cockcroft-Gault formula for estimating creatinine clearance (CrCl) should be used routinely as a simple means to provide a reliable approximation of residual renal function in all patients with The Creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is used for measuring GFR (Glomerular Filtration Rate - the flow rate of filtered fluid through the kidney). The CCr is calculated using the Cockcroft Gault equation. Cockcroft and Gault equation utilizing the tbw (Total body weight) to calculate an estimated CrCL - Cockcroft and Gault equation: CrCl = [(140 - age) x TBW] / (Scr x 72) (x 0.85 for females) Cockcroft and Gault equation utilizing the ibw (Ideal body weight) to calculate an estimated creatinine clearance Creatinine clearance (CrCl) estimation can be performed by the Cockcroft–Gault (CG) formula [ 11 ].
Calculating creatinine clearance was a "simple" resident research project designed by Dr. Henry Gault, my mentor at the time. We set out to evaluate the accuracy of a creatinine clearance nomogram by Siersbaek-Nielsen (1971). Our data, almost identical to that used to create the nomogram, resulted in our formula.

Males = (140-age) x weight (kgKilogram) / 0.814 x plasma creatinine (umol/L) Lastly, it is important to keep in mind that the Cockcroft Gault equation is merely an estimation of the CrCl and not an absolute number.
