Creatinine Clearance Calculator

Estimate glomerular filtration rate (GFR) using creatinine clearance, vital for assessing kidney function and drug dosing.

Kidney function is a critical factor in how the body processes and eliminates many medications. When the kidneys are not functioning at full capacity, drugs can accumulate to toxic levels. The Creatinine Clearance (CrCl) estimate provides a window into the kidneys' filtration rate, allowing clinicians to safely adjust dosages for patients with renal impairment.

Estimated CrCl (Cockcroft-Gault)

64.5mL/min

Estimated CrCl is 64.5 mL/min (Cockcroft-Gault)

((140 - Age) * Weight) / (72 * SCr_mgdl)
Age (years)65
重量(kg)70 kg
Serum creatinine100 µmol/L
セックスMale

使い方

The Cockcroft-Gault formula uses age, weight, and serum creatinine levels, with a 15% reduction factor for female patients to account for lower average muscle mass.

計算式

CrCl = [(140-age) × weight] / (72 × SCr) {× 0.85 if F}

計算例

1. **Male**: 60y, 80kg, SCr 1.2 = **74 mL/min**.
