Glomerular Filtration Rate

A glomerular filtration rate (GFR) is the measure of blood that passes through the kidneys per minute, which is used to determine the function of the kidneys. A blood sample is taken, and the creatinine level of your blood is combined with various other factors, and the glomerular filtration rate is estimated. If the GFR is above 90 mL/min, it indicates minimal or no function loss, whereas if it is 15 mL/min or below that, it suggests renal failure.
