Detailed explanation-1: -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.
Detailed explanation-2: -Definition. Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood.
Detailed explanation-3: -Normal GFR varies according to age, sex, and body size; in young adults it is approximately 120 ml/min/1.73 m2 and declines in normal individuals with age.
Detailed explanation-4: -A low GFR means your kidneys aren’t filtering your blood as well as they should. A GFR under 60 means you have kidney disease. If the number is below 15, you have kidney failure and will need dialysis or a kidney transplant.
Detailed explanation-5: -In a healthy individual, an average of 1100-1200 ml of blood is filtered by the kidneys per minute.
