MDRD 5 Variable Formula

**Semantic type:** Quantitative Concept

**Definition:** A formula to estimate glomerular filtration rate that takes into account age, sex, race, serum creatinine and serum urea nitrogen. eGFR (mL/min/1.73 m = 270 x creatinine (mg/dl)^-1.007 x age^-0.180 x 1.178 (if black) x 0.762 (if female) x serum urea nitrogen^-0.169.
