Kidney Station

What is Kidney GFR and Why is it Important? Kidney function is an expression of how well the kidneys are working. It is measured in terms of the glomerular filtration rate (GFR), which is the amount of blood that is filtered through the kidneys per minute. A Measurement of kidney function is important for several reasons. An abnormally high or low GFR may indicate kidney disease, and kidney function can be a factor in determining fluid balance and nutrition. The GFR can also be a factor in determining hydration status and kidney stone risk. A person's GFR declines gradually with age as the kidneys lose their filtering ability . Kidney GFR Levels in Disease States The GFR is calculated by dividing the glomerular filtration rate (GFR) by the body surface area (BSA). The following are the stages of chronic kidney disease, as established by Kidney Disease Outcomes Quality Initiative (KDOQI) Guidelines: Stage 1: Kidney function is normal but creatinine level is elevated
