Estimated Glomerular Filtration Rate (eGFR) Calculator
This calculator simultaneously computes four estimated glomerular filtration rate (eGFR) formulas.
(※Body weight is only needed for Cockcroft-Gault formula.)
Serum Creatinine (mg/dL) :
Age (year) :
[Optional] Body Weight (kg) :
|
eGFR (1): Cockcroft-Gault formula (mL/min)
eGFR (2): MDRD formula (mL/min/1.73㎡)
eGFR (3): CKD-EPI (2009) creatinine formula (mL/min/1.73㎡)
eGFR (4): CKD-EPI (2021) creatinine formula (mL/min/1.73㎡)
Formulas Used in This Calculator
(1) Cockcroft-Gault Equation (mL/min)
- Male : 1, Female : 0.85
- Scr : mg/dL
(2) MDRD eGFR (mL/min/1.73m²)
- Male : 1, Female : 0.742
- Black : 1.212, Non-black : 1
- Scr : mg/dL
(3) CKD-EPI (2009) eGFR (mL/min/1.73m²)
