Creatinine Clearance (CrCl) can be calculated using the Cockcroft-Gault formula:


Consider a 40-year-old male with a weight of 70 kg, serum creatinine of 1.2 mg/dL, and a body surface area of 1.83 m².


Q: What is Creatinine Clearance?

A: Creatinine clearance is a measure of the kidneys’ ability to filter and remove creatinine from the blood, indicating kidney function.

Q: Why use the Cockcroft-Gault formula?

A: The Cockcroft-Gault formula is widely accepted for estimating creatinine clearance, providing a reasonably accurate assessment of renal function.

Q: Can the calculator be used for all age groups?

A: Yes, the calculator is applicable to adults. For pediatric patients, other formulas or methods are recommended.

Q: What does body surface area (BSA) mean?

A: BSA is a measure used to estimate the body’s total skin area and is used in the Cockcroft-Gault formula for more accurate results.
