Estima tu Tasa de Filtración Glomerular para evaluar la función renal.
The Glomerular Filtration Rate (GFR) measures how well your kidneys filter waste from your blood. This calculator uses the CKD-EPI 2021 race-free equation — the latest standard recommended by KDIGO — to estimate your eGFR from a serum creatinine blood test result. It then classifies your kidney function into the appropriate CKD stage (1–5).
