Creatinine clearance (Cockcroft-Gault)

Estimated creatinine clearance from age, weight, sex, and serum creatinine (SI form).

Result

Fill the inputs to compute.

Interpretation
Used chiefly for renal drug dosing; eGFR equations (CKD-EPI) stage kidney disease.
Limitations
Assumes steady-state creatinine: meaningless during evolving AKI. Extremes of body composition distort it.
