About the Creatinine Clearance (Cockcroft-Gault)
The Cockcroft-Gault equation estimates creatinine clearance (CrCl) as a surrogate for GFR. It is widely used for drug dose adjustments in renal impairment.
How it works
CrCl = \frac{(140 - \text{age}) \times \text{weight} \times F}{\text{creatinine (\mu mol/L)}}Tips to improve your result
- 1.
F = 1.23 for males, 1.04 for females. Results in mL/min.
