CKD-EPI Creatinine-Cystatine C 2021 Formula

**Semantic type:** Quantitative Concept

**Definition:** A formula to estimate glomerular filtration rate that takes into account sex, age, serum creatinine (SCr) and serum cystatin C (Scys). eGFR(mL/min/1.73 m2)=135 x min(SCr/k, 1)a x max(SCr/k, 1)-0.544 x min(Scys/0.8, 1)-0.323 x max(Scys/0.8, 1)-0.778 x 0.9961^Age x 0.963 [if female].
