Assumptions for the use of this Adult Creatinine Clearance (CrCl) Calculator The patient is > 18 years of age The renal function is considered stable (i.e., not in acute renal failure)

Sep 07, 2017 · 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)

Sep 09, 2019 · Creatinine clearance ( CrCl) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus). The additional proximal tubule secretion falsely elevates the …

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%.

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.

Sep 07, 2017 · Cockcroft and Gault equation utilizing the ibw (Ideal body weight) to calculate an estimated creatinine clearance Cockcroft and Gault equation: CrCl = [(140 - age) x IBW] / (Scr x 72) (x 0.85 for females)

Estimating creatinine clearance in elderly patients with ...

The accuracy of creatinine clearance (CLcr) estimates generated for elderly patients with a low serum creatinine (SCr) concentration when the SCr concentration was rounded to 1.0 mg/dL was evaluated, and daily aminoglycoside dosages calculated with CLcr estimates based on the actual and the rounded SCr concentrations were compared with the actual dosage required as determined by aminoglycoside …

Creatinine Clearance | Calculators | Medical College of ...

Creatinine Clearance = [[140 - age(yr)]*weight(kg)]/[72*serum Cr(mg/dL)] (multiply by 0.85 for women). The results you receive from this tool are for informational purposes only and should not be the basis of your medical decision making.

Sep 09, 2019 · Method Description: CrCl or GFR: Most appropriate method for drug dosing: 30 mL/min The Cockcroft-Gault equation is the gold standard for estimating renal function for the purposes of drug dosing. Because this patient is obese (BMI ≥ 30 m 2 or > 25% ideal body weight), the Cockcroft-Gault (with 40% adjustment) method should be used. . Because of the patient's age (> 60 years), there is a ...

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. Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet. Cockcroft and Gault equation utilizing the adjusted body weight to calculate an estimated creatinine clearance. CrCl = [(140 - age) x AjBW] / (Scr x 72)

Creatinine Clearance methods 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)

How is CrCL calculated according to the Cockcroft-Gault equation?

Creatinine Clearance (Cockcroft-Gault Equation) Calculates CrCl according to the Cockcroft-Gault equation. For use in patients with stable renal function to estimate creatinine clearance. Can be used to estimate kidney function for CKD staging. Can be used to adjust or discontinue medications based on kidney function.

Some clinicians will make adjustments based on the actual weight of the patient in relation that patient's ideal body weight (IBW) and/or adjusted body weight (ABW), especially if their actual body weight is greater than 20% over the IBW. Failing to consider the actual weight of the patient could also grossly overestimate the CrCl.
