health.creatinine-clearance-Cockcroft Calculator
Calculates creatinine clearance (CrCl) using the Cockcroft-Gault formula, the most widely validated equation for drug dose adjustment in renal impairment. FDA drug labels specify renal dose adjustments using CrCl by Cockcroft-Gault — it remains the regulatory standard despite CKD-EPI's superiority for CKD staging.
Inputs
Age Years
Age in completed years. Many health and fitness formulas adjust for age.
Weight Kg
Body or object weight. For health calculators, usually in kg or lbs.
Creatinine Umol L
Reference formula or conversion factor shown for context.
Sex 1F 0M
Reference formula or conversion factor shown for context.
Results
creatinine clearance CrCl (mL/min)
Blood creatinine — a waste product filtered by the kidneys. Elevated levels indicate reduced kidney function. Normal: 0.7-1.3 mg/dL (men), 0.5-1.1 mg/dL (women).
adjusted for BSA (mL/min/1.73m²)
BSA (body surface area) -- total skin surface in m2. Estimated by the Mosteller or DuBois formula. Used for chemotherapy dosing, burn assessment, and cardiac indices.
CrCl = (140-age)×W/(72×Scr) × 0.85 if female
Reference formula or conversion factor shown for context.
drug dosing stage
The phase or stage in the progression determined by the computed value.
CG vs CKD-EPI
Reference formula or conversion factor shown for context.
serum creatinine (mg/dL)
Blood creatinine — a waste product filtered by the kidneys. Elevated levels indicate reduced kidney function. Normal: 0.7-1.3 mg/dL (men), 0.5-1.1 mg/dL (women).
