Creatinine Clearance (Cockcroft)
The Cockcroft-Gault equation estimates kidney filtration clearance factoring in serum creatinine, age, gender, and body weight.

Physiological Reference Ranges
The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.
80 – 140 mL/min
80 – 130 mL/min
90 – 140 mL/min
What does a low result mean?
A moderate clearance (60 to 89 mL/min) is common with natural aging and mainly guides medication dose tailoring.
What does a high result mean?
A clearance above 90 mL/min reflects robust and optimal glomerular filtration efficiency.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Is this clearance completely expected for my age and physical build?
- How does this harmonize with the newer CKD-EPI eGFR equation?
- Do any of my routine medications require dose fine-tuning based on this number?
Do you have a full blood test report?
