What is this Online GFR Calculator for?

The GFR Calculator estimates the Glomerular Filtration Rate (eGFR), which is the best test to measure your level of kidney function and determine your stage of kidney disease.

How does it work?

It uses the CKD-EPI Creatinine Equation (2009), which takes into account serum creatinine, age, gender, and race.
