Creatinine Clearance vs Age
सूत्र
Cockcroft-Gault Equation
CrCl = [(140 - Age) x Weight(kg)] / [72 x Serum Creatinine] x (0.85 if female)
This equation estimates creatinine clearance as a proxy for glomerular filtration rate (GFR).
Kidney Function Stages
हल किया गया उदाहरण
A 50-year-old male, 80 kg, serum creatinine 1.0 mg/dL.
- 01CrCl = (140 - 50) x 80 / (72 x 1.0)
- 02= 90 x 80 / 72
- 03= 7200 / 72 = 100 mL/min (Normal)
अक्सर पूछे जाने वाले प्रश्न
What is creatinine clearance?
Creatinine clearance measures how well the kidneys filter creatinine from the blood. It serves as an estimate of the glomerular filtration rate (GFR).
Why is this equation important?
The Cockcroft-Gault equation is widely used for adjusting drug dosages in patients with reduced kidney function. Many drug labels reference this equation.
What is a normal creatinine level?
Normal serum creatinine is typically 0.7-1.3 mg/dL for men and 0.6-1.1 mg/dL for women. Higher values may indicate reduced kidney function.
