CKD-Epi Equation for eGFR
The CKD-EPI equation is used to estimate glomerular filtration rate in chronic kidney failure.
eGFR = 141 × (Creatinine/X)Y × 0.993Age ( × 1.018 if female) ( × 1.159 if african origin)
Female:
Cr ≤0.7mg/dL (62µmol/L): X = 0.7; Y = -0.329
Cr >0.7mg/dL (62µmol/L): X = 0.7; Y = -1.209
Male:
Cr ≤0.9mg/dL (80µmol/L): X = 0.9; Y = -0.411
Cr >0.9mg/dL (80µmol/L): X = 0.9; Y = -1.209
Female:
Cr ≤0.7mg/dL (62µmol/L): X = 0.7; Y = -0.329
Cr >0.7mg/dL (62µmol/L): X = 0.7; Y = -1.209
Male:
Cr ≤0.9mg/dL (80µmol/L): X = 0.9; Y = -0.411
Cr >0.9mg/dL (80µmol/L): X = 0.9; Y = -1.209
