GFR stands for Glomerular Filtration Rate.
What does GFR mean?
a measure of how well the kidneys filter blood
GFR stands for glomerular filtration rate, a measure of how much blood the kidneys filter each minute, and the best overall test of kidney function. It reflects how well the tiny filtering units of the kidney, the glomeruli, are working. In practice it is usually estimated from a blood creatinine level along with age and other factors, and reported as eGFR. A normal GFR is about 90 or above, while a value below 60 for three months or more suggests chronic kidney disease, and below 15 indicates kidney failure.
When is GFR used?
GFR is reported on routine blood tests and is used to stage chronic kidney disease across primary care and nephrology.
