How should the Cockcroft-Gault estimate be adjusted for female patients?

Creating an accurate Cockcroft-Gault estimate requires accounting for sex because creatinine production is tied to muscle mass, which tends to be lower in females. The standard approach uses the male-based formula and then applies a multiplier for women to reflect this difference. Multiply the calculated CrCl by 0.85 for females, reducing the estimate by about 15%. In other words, CrCl ≈ [(140 − age) × weight] / (72 × serum creatinine), and if the patient is female, apply the 0.85 factor. This adjustment aligns the estimate with the typically lower muscle mass and creatinine production seen in women.
