What is the formula to calculate gfr

White or otherFemaleGFR = 144 × (Scr/61.9)-0.329 × (0.993)Age

White or otherFemaleGFR = 144 × (Scr/61.9)-1.209 × (0.993)Age

White or otherMaleGFR = 141 × (Scr/79.6)-0.411 × (0.993)Age

White or otherMaleGFR = 141 × (Scr/79.6)-1.209 × (0.993)Age

Expressed as a single equation:

eGFR =

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]

Abbreviations / Units

eGFR (estimated glomerular filtration rate) = mL/min/1.73 m2

SCr (standardized serum creatinine) = mg/dL

κ = 0.7 (females) or 0.9 (males)

α = -0.329 (females) or -0.411 (males)

min = indicates the minimum of SCr/κ or 1

max = indicates the maximum of SCr/κ or 1

age = years

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
