Question 1

What is a Creatinine Clearance?

Accepted Answer

Creatinine clearance (CrCl) estimated by the Cockcroft-Gault equation is used for drug dosing (especially renally-cleared medications), whereas eGFR is used for CKD staging. They give similar but not identical values.

Question 2

How does the Creatinine Clearance work?

Accepted Answer

CrCl = [(140−Age) × Weight(kg)] / (72 × Serum creatinine mg/dL) Then: Multiply by 0.85 for females Then: Uses actual body weight; in obesity, use ideal body weight or adjusted body weight Then: Important for dosing: aminoglycosides, vancomycin, metformin, direct oral anticoagulants.

Question 3

Can you give an example of how to use the Creatinine Clearance?

Accepted Answer

Example: Input Male age 65 · weight 75kg · creatinine 1.3mg/dL gives a result of CrCl = (140−65)×75/(72×1.3) = 60.1 mL/min (Requires dose adjustment for many drugs).
