Equations to predict glomerular filtration rate using serum creatinine-derived eGFR
Name | Formula |
---|---|
MDRD 4 variable (IDMS non-traceable) | eGRF (mL/min/1.73 m2)=186×(Scr)−1.154×(age)−0.203×(1.210 if patient black)× (0.742 if patient is female) |
MDRD 4 variable (IDMS traceable) | eGRF (mL/min/1.73 m2)=175×(Scr)−1.154×(age)−0.203×(1.210 if patient is black)× (0.742 if patient is female) |
CKD-EPI | eGRF (mL/min/1.73 m2)=141×min (Scr/k, 1)a×max (Scr/k, 1)−1.209×0.993age× 1.018 [if female]×1.159 [if black] |
k is 0.7 for females and 0.9 for males, a if −0.329 for females and −0.411 for males min indicates the minimum of Scr/k or 1, and max indicates the maximum of Scr/k or 1 | |
BIS | eGRF (mL/min/1.73 m2)=3736×(Scr)−0.87×age−0.95×0.82 [if female] |
Age in given in years, serum creatinine in mg/dL.
eGFR, estimated glomerular filtration rate; MDRD, modification of diet in renal disease; IDMS, isotope dilution-mass spectrometry; CKD-EPI, Chronic Kidney Disease Epidemiology Collaboration; Scr, serum creatinine; BIS, Berlin Initiative Study.
