Formula

#
Formula principal
eGFR=142×min⁡ ⁣(Scrκ, 1) ⁣α×max⁡ ⁣(Scrκ, 1) ⁣−1.200×  0.9938Age×[1.012 if female]eGFR = 142 \times \min\!\left(\frac{S_{cr}}{\kappa},\, 1\right)^{\!\alpha} \times \max\!\left(\frac{S_{cr}}{\kappa},\, 1\right)^{\!-1.200} \\ \times \; 0.9938^{\text{Age}} \times [1.012 \text{ if female}]

Como funciona: A equacao CKD-EPI usa creatinina serica, idade e sexo para estimar a taxa de filtracao glomerular.

Exemplo Resolvido

Creatinina 1,0 mg/dL, mulher de 50 anos -> TFG estimada ~75 mL/min/1,73m^2.

KDIGO CKD Risk Heat Map

The risk of CKD progression and cardiovascular events based on eGFR (G-Stage) and Albuminuria (A-Stage).

GFR StageeGFR RangeA1 (<30)A2 (30-300)A3 (>300)

Risk classifications are based on KDIGO 2024 Clinical Practice Guidelines. High-risk categories indicate a higher likelihood of progression to kidney failure or cardiovascular complications.
