Is the kidney functional when glomerular filtration rate is zero?

No, the kidney is not functional when the glomerular filtration rate (GFR) is zero.

GFR is a measure of the rate at which blood is filtered by the kidneys. It is an important indicator of kidney function. A GFR of zero means that the kidneys are not filtering any blood and therefore not producing urine. This can be caused by a variety of conditions, including kidney failure, kidney disease, and urinary tract obstruction.

When GFR is zero, the kidneys are unable to perform their essential functions, such as:

- Removing waste products from the blood

- Regulating fluid and electrolyte balance

- Producing hormones such as erythropoietin and renin

Without these functions, the body can become seriously ill and even die. Therefore, it is important to seek medical attention immediately if you have a GFR of zero.
