Kidney Glomerular Filtration Rate

Kidney Glomerular Filtration Rate (GFR) is one of the most important measurements used to check how well your kidneys are working. It tells doctors how effectively the kidneys are filtering waste products and excess fluids from the blood. If you are concerned about kidney health, understanding GFR can help you detect problems early and take proper action.

Glomerular Filtration Rate (GFR) refers to the amount of blood that passes through the tiny filters in the kidneys, called glomeruli, each minute. The kidneys contain millions of these microscopic filters that remove toxins, waste products, and extra water from the bloodstream.

When the kidneys are healthy, they efficiently filter the blood and maintain the body's balance of fluids and electrolytes. A reduced GFR indicates that kidney function is declining.
