Creatinine clearance (CrCl) measures the rate at which kidneys filter creatinine from blood plasma. It serves as a vital clinical index for renal health and medication dosing.

Formula
The Cockcroft-Gault equation estimates creatinine clearance from serum creatinine level, age, sex, and weight.
Cockcroft-Gault Formula (Male)
CrCl = ((140 - age) · weight) / (72 · serum creatinine)Cockcroft-Gault Formula (Female)
CrCl = CrCl(male) · 0.85Frequently asked questions
What is a normal creatinine clearance rate?
Normal creatinine clearance is generally 97 to 137 mL/min for adult males and 88 to 128 mL/min for adult females.
What does low creatinine clearance indicate?
A clearance rate below 60 mL/min for 3 months or more indicates reduced kidney function and warrants medical evaluation.
