17 In essence, this correction accounts for 40% of body mass above a patient's "ideal" body weight: The Cockcroft-Gault LBW equation was the most precise, and the MDRD4 equation was the least. The Cockcroft-Gault FFW and Cockcroft- Gault LBW equations yielded the highest accuracy (55-61%), in yielding values that were within 30% of the measured CL cr . Please note: When estimating a creatinine clearance for an obese patient an estimate of the non-obese or ideal body weight (IBW) should be used. Ideal body weight for males in kg = 50 + (2.3) (height in inches > 60) Ideal body weight in females in kg = 45 + (2.3) (height in inches > 60) Two methods were used to estimate renal function: the Cockcroft-Gault formula for creatinine clearance in ml/min ((140 - age in years) x body weight in kg/ (serum creatinine in umol/l x 0.81) x 0.85 if female); and Modification of Diet in Renal Disease (MDRD) formula for glomerular filtration rate (GFR) in ml/min/1.73 m2 (186.3 x (age in years (-0.203)) x serum creatinine in umol/l/ (88.4 (-1.154)). Plasma creatinine (mg/dL) Age (yr) Estimated creatinine clearance: Body mass (kg) (mL/min) The Cockcroft-Gault formula was used to calculate CrCl, utilizing the patients’ actual body weight and correction for gender within the equation, in phase 1 and phase 3 studies assessing renal function during XARELTO use. 5

Although creatinine clearance slightly overestimates the glomerular function by 10-20%, it is considered the standard for drug dosing adjustments. 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) The Cockcroft-Gaultformula for estimating creatinine clearance (CrCl) should be used routinely as a simple meansto provide a reliable approximation of residual renal function in all patients with CKD. CrCl(male) = ([140-age] × weight in kg)/(serum creatinine × 72) CrCl(female) = CrCl(male) × 0.85.

With the use of internationally standardized creatinine measurements, the equation significantly overestimates the GFR (10-40%). 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.

Nephron, 16:31-41, 1976: MDRD GFR Calculator: KDOQI Guidelines: Nephron Information Center: by Stephen Z. Fadem, M.D. 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 CKD. The formulas are as follows: CrCl (male) = ([140-age] × weight in … 2020-02-06 Cockcroft Gault’s Formula : Creatinine Clearance Value ( Male ) = ( ( 140 – age ) ( weight kg ) / ( 72 X Scr ) ) Creatinine Clearance Value ( Female )= 0.85 * ( ( 140 – age ) ( weight kg ) / ( 72 X Scr ) ) Cockcroft-Gault CrCl = [(140-age) x (Wt in kg) x (0.85 if female)] / (72 x Cr) Note: The original Cockroft-Gault Equation listed here provides an estimate of creatinine clearance, but this original formula is not adjusted for body surface area and may be less accurate in obese patients.The Cockroft-Gault Equation typically overestimates creatinine clearance by approximately 10 to 30%. Kidney Function: Cockcroft-Gault is a formula used to determine how well your kidneys function. It is expressed as a Creatinine Clearance in ml/min and is adjusted for … formula advocated by contemporary consensus [4, 9, 10].

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.
