**Semantic type:** Quantitative Concept

**Definition:** A formula to estimate glomerular filtration rate that takes into account sex, age, race, and serum creatinine (SCr). eGFR(mL/min/1.73 m2)=141 x min(SCr/k, 1)^a x max(SCr/k, 1)^-1.209 x 0.993^Age x 1.018 [if female] x 1.159 [if black] where: SCr is in mg/dL; k=0.7 for Female and 0.9 for Male; a=-0.329 for female and -0.411 for male; additional multiplication of the result of the 2009 CKD-EPI formula with the factor 0.813.
