Creatinine Clearance – FAQ
1. What is creatinine clearance?
Creatinine clearance (CrCl) is an estimate of how effectively your kidneys filter creatinine from your bloodstream. It reflects kidney filtration capacity in mL/min.
2. How is creatinine clearance calculated?
It can be measured using a 24-hour urine test or estimated using formulas such as the Cockcroft–Gault equation, which uses age, weight, sex, and serum creatinine.
3. What is a normal creatinine clearance?
Typically, CrCl ≥ 90 mL/min is considered normal. Values between 60–89 indicate mild kidney impairment, and lower values indicate progressively reduced kidney function.
4. Why is creatinine clearance important?
It helps clinicians assess kidney health, stage kidney disease, and adjust medication doses for drugs eliminated through the kidneys.
5. Is creatinine clearance the same as eGFR?
No. Creatinine clearance estimates kidney filtration based on creatinine removal, while eGFR (like CKD-EPI) uses mathematical models based on serum creatinine, age, and sex.
