Creatinine clearance Cockcroft and Gault
- Cockcroft and Gault formula:
- Creatinine clearance (mL/min) Males = (140-age) x weight (kg) / 0.814 x plasma creatinine (umol/L) Creatinine clearance (mL/min)
- Variations include estimating ideal body weight from patient height in obese subjects.
What is CRCL 30 mL min?
Renal failure causes reduced creatinine clearance. Creatinine clearance values of 30 to 40 mL/min/1.73 m2 suggest moderate renal impairment, while values <28 suggest severe impairment. Creatinine clearance may not be accurate in the following medical conditions.
What weight should I use for Cockcroft-Gault?
Cockcroft and Gault equation utilizing the ibw (Ideal body weight) to calculate an estimated creatinine clearance. actual body weight for calculating the CRCL. 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.
What is modified Cockcroft-Gault?
A modified Cockcroft-Gault formula taking into account the body surface area gives a more accurate estimation of the glomerular filtration rate. J Nephrol.
How do you convert umol L to mg DL?
To convert μmol/l to mg/dl, multiply by 0.0113. To convert mg/dl to μmol/l, multiply by 88.4.
How is ClCr calculated?
Creatinine Clearance (ClCr): Estimate using the Cockcroft-Gault equation: ClCr (mL/min) = 1.2 (140 – age) (weight in kg) Serum creatinine (µmol/L) For females, multiply result by 0.85.
What is modified Cockcroft Gault?
How do you calculate CrCl?
Creatinine Clearance Calculator 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.
Can you calculate CrCl without height?
Creatinine Clearance (CrCl) You cannot choose the incorrect weight. Example: MR’s TBW is 90 kg, IBW 59.2 kg, and AdjBW is 71.3 kg. If no height is provided, you can only use TBW because you cannot calculate IBW without height.
What is the formula for calculating GFR?
| Race | Sex | Equation (age in years for ≥ 18) |
|---|---|---|
| White or other | Female | GFR = 144 × (Scr/61.9)-0.329 × (0.993)Age |
| White or other | Female | GFR = 144 × (Scr/61.9)-1.209 × (0.993)Age |
| White or other | Male | GFR = 141 × (Scr/79.6)-0.411 × (0.993)Age |
| White or other | Male | GFR = 141 × (Scr/79.6)-1.209 × (0.993)Age |

How do you calculate the Cockcroft Gault equation?
Cockcroft Gault Calculator – (With SI Units) 4 variable Cockcroft Gault equation (with SI Units) using serum creatinine, age, weight, gender. by Stephen Z. Fadem, M.D., FACP, FASN. (Age, Weight, Gender, Serum creatinine) Creatinine Clearance Value = (140-age)(weight kg) / (72 X Scr) in mL/min.
What is the Cockcroft-Gault formula for creatinine clearance?

Does Cockcroft-Gault equation compare with EGFR by MDRD?
A large simulation study compared eGFR by MDRD Study equation and estimated creatinine clearance (eCrCl) by the Cockcroft-Gault equation calculated from standardized creatinine values to each other and to measured GFR for the purpose of drug dosing.
How reliable is the Cockcroft-Gault equation in assessing the risk of kidney damage?
However, for drugs with a narrow therapeutic index, the Cockcroft-Gault equation was less reliable in assessing the risk of kidney damage. With permission from The National Institute of Diabetes and Digestive and Kidney Diseases, Bethesda, MD 20892-2560.
