GFR Calculator – Estimated Glomerular Filtration Rate
Estimate kidney function (eGFR) using the modern CKD-EPI formula
Clinical Guidelines: The eGFR evaluates kidney function. Normal eGFR is $\ge 90\text{ mL/min/1.73m}^2$. Stage 2 is 60–89, Stage 3 is 30–59, Stage 4 is 15–29, and Stage 5 (Kidney Failure) is $< 15$. Enter patient details below.
