Test Code N/Aautomatically calculated when serum creatinine is ordered

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
