Recommended Equations for Estimation of Glomerular Filtration Rate (GFR) Using Serum Creatinine Concentration (PCr), Age, Sex, Race, and Body Weight

1. Equation from the Modification of Diet in Renal Disease studya

Estimated GFR (mL/min per 1.73 m2) = 1.86 x (PCr)–1.154 x (age)–0.203

Multiply by 0.742 for women

Multiply by 1.21 for African Americans

2. Cockcroft-Gault equation
