公式
Formula: CrCl = ((140 − Age) × Weight) / (72 × Creatinine). Multiply by 0.85 for females (Cockcroft-Gault).
常见问题
What is creatinine clearance?
Creatinine clearance estimates the rate at which your kidneys filter creatinine from the blood. It is used to assess kidney function and adjust drug dosages.
What does the Cockcroft-Gault equation measure?
It estimates glomerular filtration rate (GFR) from serum creatinine, age, weight, and sex. The result is measured in mL/min.
What is a normal creatinine clearance?
Normal values are approximately 90-140 mL/min for men and 80-125 mL/min for women. Values decrease naturally with age.
