Calculator for the estimated glomerular filtration rate (eGFR)

The GFR describes how many millilitres of blood the tiny filters (glomeruli) in your kidneys can filter within one minute.

If the glomeruli are not filtering enough blood to keep the body in a healthy state, the kidneys have an impaired or reduced function.

Defined by the level of GFR, there are 5 stages of chronic kidney disease (according to NKF-KDOQI Guidelines [1]). Stage 1 is the earliest, while Stage 5 represents kidney failure or end-stage renal disease (ESRD), respectively.
