Glomerular filtration rate (GFR) calculator
Your glomerular filtration rate (GFR) is a measure of your kidney function. Your GFR can be estimated from a routine measurement of creatinine in your blood. 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. In other words, if your GFR is too low, your kidneys may not be able to remove enough waste and redundant water from your blood.
Stages of chronic kidney disease on the basis of GFR
Defined by the level of GFR, there are 5 stages of chronic kidney disease (according to NKF-KDOQI Guidelines ). Stage 1 is the earliest, while Stage 5 represents kidney failure or end-stage renal disease (ESRD), respectively.
