What is the Cockcroft-Gault equation?

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 kg)/(serum creatinine × 72)

What is the formula for creatinine clearance?

Creatinine Clearance Calculator Est. Creatinine Clearance = [[140 – age(yr)]*weight(kg)]/[72*serum Cr(mg/dL)] (multiply by 0.85 for women).

What is 140 in Cockcroft-Gault formula?

The Cockcroft-Gault formula reads: GFR estimate = (140 − age (years) × weight (kg) × constant/serum creatinine(μmol/L)The published constants are 1.23 for males of any age, and 1.05 for females of any age[4].

How do you calculate 24 hour creatinine clearance?

To calculate creatinine clearance, the creatinine level in the urine is multiplied by the total volume of urine produced over 24 hours. This is then divided by the amount of creatinine in the blood. The final value is converted to milliliters of blood per minute (mL/min).

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.

What is CKD-EPI creatinine equation?

The CKD-EPI equation, expressed as a single equation, is GFR = 141 × min(Scr/κ, 1)α × max(Scr/κ, 1)-1.209 × 0.993Age × 1.018 [if female] _ 1.159 [if black], where Scr is serum creatinine, κ is 0.7 for females and 0.9 for males, α is -0.329 for females and -0.411 for males, min indicates the minimum of Scr/κor 1, and …

What is normal creatinine clearance range?

Clearance is often measured as milliliters per minute (mL/min) or milliliters per second (mL/s). Normal values are: Male: 97 to 137 mL/min (1.65 to 2.33 mL/s). Female: 88 to 128 mL/min (14.96 to 2.18 mL/s).

What are normal GFR values?

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.

What is 24-hour urine creatinine?

Normal Results Urine creatinine (24-hour urine collection) values can range from 500 to 2000 mg/day (4,420 to 17,680 mmol/day). Results depend on your age and amount of lean body mass.

What is Calc CrCl by Cockcroft-Gault?

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.
