Test Details
Estimated Glomerular Filtration Rate (eGFR) / Creatinine
Glomerular filtration rate (GFR) provides a measure of kidney filtering capacity. Total GFR can be used as an index of functioning renal mass. Estimated GFR (eGFR)/Creatinine is calculated based on serum creatinine, age, and gender.
Methodology
Serum creatinine and age are used to calculate eGFR, taking gender into account. The specific equation used is:
eGFR = 142 x min(Scr/κ, 1)α x max(Scr/κ, 1)-1.200 x 0.9938Age x 1.012 [if female]
Scr = serum creatinine in mg/dL
κ = 0.7 if female
κ = 0.9 if male
α = -0.241 if female
α = -0.302 if male
min = The minimum of Scr/κ or 1.0
max = The maximum of Scr/κ or 1.0
