GFR Calculation Formula

The GFR (Glomerular Filtration Rate) is estimated using the following formula:

eGFR = 141 × min(Serum Creatinine/κ, 1)α × max(Serum Creatinine/κ, 1)-1.209 × 0.993Age × Gender Multiplier

Where:

  • κ is 0.7 for females and 0.9 for males.
  • α is -0.329 for females and -0.411 for males.
  • The Gender Multiplier is 1.018 for females and 1 for males.
  • Serum Creatinine is in mg/dL, converted if necessary.
