Inputs

Patient Name: Room:

Age: Scr:

Race:

Equation:

Program is based on the following:

GFR = 141 x min(Scr/κ,1)^α x max(Scr/κ,1)^-1.209 x 0.993^Age x 1.018 [if female]
x 1.159 [if black]

κ = 0.7 if female.
κ = 0.9 if male.

α = -0.329 if female
α = -0.411 if male

min = the minimum of Scr/κ or 1
max = the maximum of Scr/κ or 1

"BACKGROUND: Equations to estimate glomerular filtration rate (GFR) are routinely used to assess kidney function. Current equations have limited precision and systematically underestimate measured GFR at higher values."¹

"CONCLUSION: The CKD-EPI creatinine equation is more accurate than the Modification of Diet in Renal Disease Study equation and could replace it for routine clinical use."¹
