Patient Name:    Room:
Age:        Scr 


Program is based on the following:

GFR = 141 x min(Scr/κ,1)α x max(Scr/κ,1)-1.209 x 0.993Age 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
