Glomerular Filtration Rate (GFR)
Calculate the GFR using the The Modification of Diet in Renal Disease (MDRD) Study equation.
GFR (mL/min/1.73 m2) = 175 × (Scr)-1.154 × (Age)-0.203 × (0.742 if female) × (1.212 if African American)
The equation does not require weight or height variables because the results are reported normalized to 1.73 m2 body surface area, which is an accepted average adult surface area.
Scr = Serum Creatinine level
