GFR Calculation Formula

The estimated GFR (eGFR) is calculated using the CKD-EPI equation:

eGFR = 141 × min(SCr/κ, 1)^α × max(SCr/κ, 1)^-1.209 × 0.993^Age × GenderFactor
    

• SCr = Serum Creatinine in mg/dL
• κ = 0.7 (female), 0.9 (male)
• α = -0.329 (female), -0.411 (male)
• GenderFactor = 1.018 (female), 1 (male)

eGFR is a key indicator used to assess kidney health and detect chronic kidney disease (CKD).
