Frequently Asked Questions

What does creatinine clearance measure?

Creatinine clearance estimates how efficiently the kidneys filter waste from the blood, serving as a practical proxy for glomerular filtration rate, used clinically to assess kidney function and adjust dosing of renally-cleared medications.

Why does the formula adjust for gender?

The Cockcroft-Gault formula applies a correction factor for women to account for typically lower average muscle mass, since creatinine is a byproduct of muscle metabolism and muscle mass affects baseline creatinine production.

Is this the same as eGFR reported on standard lab results?

Not exactly — many labs now report eGFR using newer formulas like CKD-EPI, which can differ somewhat from Cockcroft-Gault, though both serve the similar purpose of estimating kidney filtration function.
