medlineplus.gov/lab-tests/glomerular-filtration-rate-gfr-test/

A glomerular filtration rate (GFR) is a blood test that checks how well your kidneys are working. Your kidneys have tiny filters called glomeruli. These filters help remove waste and excess fluid from the blood. A GFR test estimates how much blood passes through these filters each minute. A GFR can be measured directly, but it is a complicated ...
