What is creatinine clearance Cockcroft-Gault formula?
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 calculating creatinine clearance?
Creatinine Clearance Calculator Est. Creatinine Clearance = [[140 – age(yr)]*weight(kg)]/[72*serum Cr(mg/dL)] (multiply by 0.85 for women).
When do you use the Cockcroft-Gault equation?
Creatinine Clearance (Cockcroft-Gault Equation)
- Can be used to estimate kidney function for CKD staging.
- Can be used to adjust or discontinue medications based on kidney function.
What is normal creatinine clearance?
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 is a normal creatinine clearance?
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).
– Creatinine 1 mg/dL is the baseline for a given patient with normal GFR – Creatinine 2 mg/dL is 50% reduction in GFR – Creatinine 4 mg/dL is 70 to 85% reduction in GFR – Creatine 8 mg/dL is 90 to 95% reduction in GFR
How do you calculate the GFR using the Cockcroft Gault?
Actual body weight will significantly overestimate renal function

How to calculate Cockcroft Gault?
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%.
