MDRD Enzymatic Formula

**Semantic type:** Quantitative Concept

**Definition:** A formula to estimate glomerular filtration rate that takes into account age, sex, race, and serum creatinine. eGFR (mL/min/1.73 m2)=175 x (serum Cr [conv mg/dL])^-1.154 x (Age)^ -0.203 x (0.742 if female) x (1.212 if black), for conventional units. eGFR=175 x (serum Cr [SI UMOL/L]/88.4)^-1.154 x (Age)^ -0.203 x (0.742 if female) x (1.212 if black), for SI units.
